As we know that the division is to distribute a given value or quantity into groups having equal values. In long division, values at the individual place (Thousands, Hundreds, Tens, Ones) are dividend one at a time starting with the highest place.
Division of 2 Digit Number by 1 Digit Number:
Division can be shown in two ways. e.g. Short form and Long form.
A. Division by One-Digit Divisor
1. Divide 27 by 9
Solution:
Let us divide.
Step I: Write 27 inside the bracket and 9 on the left side of the bracket. Step II: Start division from left to right, that is, divide 2 by 9. Since, we cannot divide 2 by 9 so, we will divide 27 by 9. Step III: Recall the table of 9. 9 × 3 = 27 Now, write 3 in the quotient and subtract 27 from 27. The result is 0. Thus, 27 ÷ 9 = 3 |
2. Divide 92 by 4
Solution:
Let us divide.
Step I: Write 92 inside the bracket and 4 on the left side of the bracket. Step II: Start division from left to right, that is, divide 9 tens by 4. 4 × 2 = 8 4 × 3 = 12 12 tens is bigger than 9 tens, so we take 4 × 2 = 8 tens. Step III: Write 2 in the quotient. Step IV: Subtract 8 from 9 and get 1 as remainder. Step V: Bring down 2 from ones place and write it to the right of 1. 12 is the new dividend. Step VI: Write 3 in the quotient and subtract 12 from 12. The result is 0. Thus, 92÷4 = 23 |
3. Divide 36 by 3.
3 × 1 = 3 Write 1 as a quotient write 3 under 3 and subtract | |
Bring down 6 ones. Now divide 6 by 3 3 × 2 = 6 Write 2 as a quotient and write 6 under the new dividend and subtract Now, 36 divided by 3 is 12. |
4. Divide 30 by 5.
Notes:
I. Divide the Tens.
II. Then, divide the Ones.
B. Division of 3-Digit Number by One-Digit Number:
1. Divide 324 by 2.
First Divide the Hundreds
Dividing Hundreds Divide 6 H by 2 = 3H write 3 in place of quotient and 6 under 6 and subtract 6 - 6=0 |
Then, Divide the Tens.
Dividing Tens Now, bring down 4 T. Divide 4 T by 2 = 2T write 2 in tens place of the quotient and 4 under 4 then subtract 4 - 4 = 0 |
Finally, Divide the Ones.
Dividing Ones Bring down 8 Ones. Divide 8 ones by 2 = 4 ones write 4 in the ones place of the quotient. write 8 under 8 and subtract 8 - 8 = 0 |
D. Division of 4-Digits Number by 1-Digit Number:
To divide 4-Digit numbers follow these steps -
(i) Divide the Thousands.
(ii) Divide the Hundreds.
(iii) Divide the Tens.
(iv) Divide the Ones.
1. Divide 3693 by 3.
Step I: Dividing Thousands Divide 3 Th by 3 = 1Th write 1 in place of quotient and 3 under 3 and subtract 3 - 3 =0 Step II: Dividing Hundreds Bring down 6 H. Divide 6 H by 3 = 2H write 2 in place of quotient and 6 under 6 and subtract 6 - 6=0 Step III: Dividing Tens Now, bring down 9 T. Divide 9 T by 3 = 3T write 3 in tens place of the quotient and 9 under 9 then subtract 9 - 9 = 0 Step IV: Dividing Ones Bring down 3 Ones. Divide 3 ones by 3 = 1 ones write 1 in the ones place of the quotient. write 3 under 3 and subtract 3 - 3 = 0 |
2. Divide 6428 by 2.
Step I: Dividing Thousands Divide 6 Th by 2 = 3Th write 3 in place of quotient and 6 under 6 and subtract 6 - 6 =0 Step II: Dividing Hundreds Bring down 4 H. Divide 4 H by 2 = 2H write 2 in place of quotient and 4 under 4 and subtract 4 - 4=0 Step III: Dividing Tens Now, bring down 2 T. Divide 2 T by 2 = 1T write 1 in tens place of the quotient and 2 under 2 then subtract 2 - 2 = 0 Step IV: Dividing Ones Bring down 8 Ones. Divide 8 ones by 2 = 4 ones write 4 in the ones place of the quotient. write 8 under 8 and subtract 8 - 8 = 0 |
Division with Remainder:
1. Divide 49 by 4.
T: 4 ÷ 4 = 1. Quotient = 1 O: 9 ÷ 4= ? 4 × 2 = 8 (nearest number) 9 - 8 = 1 So, Quotient = 2 Remainder = 1 |
Divisor - 4, Quotient - 12, Remainder - 1.
2. Find the quotient and remainder of 649 ÷ 9.
Solution:
Step I: We start dividing the hundreds first. Since 6 hundreds cannot be divided into 9 groups of hundreds, the quotient at hundreds column is zero. Step II: 6 Hundreds are now changed into 60 tens and added to 4 tens, making 64 tens. Step III: 64 tens give 9 groups of 7 tens each and 1 ten is left over. Step IV: 1 ten give 10 ones, 10 ones + 9 ones = 19 ones Step V: 19 ones can be put into 2 groups of 9 and 1 one is left over. |
q = 72; r = 1 |
3. Divide 697 by 3.
H: 6 ÷ 3 = 2. T: 9 ÷ 3 = 3. O: 7 ÷ 3 = ? 3 × 2 = 6 (nearest number) 7 - 6 = 1 So, in O Quotient = 2 Remainder = 1 |
Divisor - 3, Quotient - 232, Remainder 1.
4. Divide 8643 by 2.
Th: 8 ÷ 2 = 4 H: 6 ÷ 2 = 3 T: 4 ÷ 2 = 2 O: 3 ÷ 2 = ? 2 × 1 = 2 3 - 2 = 1 So. in O Quotient = 2 Remainder = 1 |
Divisor - 2, Quotient - 4321, Remainder 1.
5. Divide 6609 by 6.
Th: 6 ÷ 6 = 1 H: 6 ÷ 6 = 1 T: 0 ÷ 6 = 0 O: 9 ÷ 6 = ? 6 × 1 = 6 9 - 6 = 3 So, in Quotient = 1 Remainder = 3 |
Divisor - 6, Quotient - 1101, Remainder 3.
E. Division with Regrouping:
1. Divide 96 by 4.
Step I: Dividing Tens Divide 9 ÷ 4 = ? 4 × 2 = 8 8 < 9 4 × 3 = 12 12 > 9 we use 4 × 2 = 8. write 2 in tens place of the quotient and 8 below 9 then subtract 9 - 8 = 1 |
Step II: Dividing Ones Bring down 6 Ones, we have 16 ones 1 ten+ 6 ones. Divide 16 ones ÷ 4 4 × 4 = 16 write 4 in ones place of the quotient and 16 below 16 Now, 16 - 16 = 0 |
2. Divide 736 by 3.
H: 7 ÷ 3 = ?. So, 3 × 2 =6 Q: 2; R: 7 - 6 = 1 or 1 hundreds Regroup - 1 hundreds and 3 tens = 13 tens T: 13 + 3 = ?. So, 3 × 4 = 12 Q: 4; R: 13 - 12 = 1 or 1 tens Regroup - 1 tens and 5 ones = 15 ones O: 16 ÷ 3 = ?. So, 3 × 5 = 15 Q: 5; R: 16 - 15 = 1 Remainder - 1 |
Here 3 is divisor, 736 is dividend, 245 is quotient and 1 is remainder.
3. Divide 3373 by 4.
Th: 3 < 4 so 3 + 4 is not possible. Regroup - 3 thousands and 3 hundreds = 33 hundreds H:33 ÷ 4 = ? Q: 8; R: 33 - 32 = 1 Remainder - 1 hundreds Regroup - 1 hundreds and 7 tens = 17 tens T: 17 ÷ 4 = 4 Q: 4 R: 17 - 16 = 1 Remainder - 1 tens Regroup - 1 tens and 3 ones = 13 ones O:13 ÷ 4 = 3 Q: 3 R: 13 - 12 = 1 Remainder - 1 |
Here 4 is divisor, 3373 is dividend, 845 is quotient and 1 is remainder.
Keep in Mind
Division by Two-Digit Divisors
1. Divide 2698 by 21.
Solution:
Recall the process of long division.
Step I: 2 thousands cannot be divided into 21 groups of thousand. So, 0 is placed as quotient in the thousands column. Step II: 2 thousands give 20 hundreds. 20 hundreds + 6 hundreds give 26 hundreds. 26 hundreds make 1 group of 21 hundreds. 5 hundreds are left. Step III: 5 hundreds give 50 tens. |
q = 128; r = 10 |
So, 50 tens + 9 tens = 59 tens
59 tens are to be divided into 21 groups of tens
59 tens ÷ 21 makes 2 groups with 17 tens left.
2 is placed in the quotient in the tens column.
Step IV: 17 tens = 170 ones
170 ones + 8 ones = 178 ones
178 ones ÷ 21 makes 8 groups with 10 ones left.
Thus, in division of 2,698 by 21, we get 128 as quotient and 10 as remainder.
Word Problems on Long Division:
To solve any word problem, we need to read each word carefully and select numbers carefully from the question to solve it.
1. If 60 cookies to be put in 5 packets, how many cookies will be packed in one packet?
Solution: Number of cookies = 60 cookies Equally distributed in 5 packets Number of cookies in one packet = 60 ÷ 5 |
Thus, 12 cookies will be packed in one packet.
