In division of two-digit by a one-digit numbers are discussed here step by step.
How to divide 2-digit numbers by single-digit numbers?
Let us follow the examples to learn to divide 2-digit numbers by one-digit numbers.
I: Dividing a 2-digit Number by a 1-Digit Number without Remainder:
1. Divide the following and verify the result
(i) 42 ÷ 6
(ii) 85 ÷ 5
Solution:
(i) 42 ÷ 6
Since, 6 sevens are 42, i.e., 6 × 7 = 42
So, 7 will be quotient
6 × 7 + 0 = 42, the dividend
So, quotient 7 is verified
Therefore, 7 is quotient
(ii) 85 ÷ 5
(a) 8 > 5 so first 8 will be divided. 8T ÷ 5 = 1T so quotient will be 1 ten
(b) 8T - 5T = 3T, 3T + 5 = 35 for 35 ÷ 5, 5 × 7 = 35.
So 7 is quotient
(c) 5 × 17 = 85 (dividend)
So, result is verified.
Therefore, Quotient = 17, remainder = 0
2. Divide 77 by 7
We proceed as follows:
Step I: Arrange the two given numbers as shown.
Step II: Divide the tens by 7.
We know 7 × 1 = 7.
Write 1 in tens place of the quotient and 7 below 7.
Subtract 7 from 7 to get 0.
Step III: Bring down 7 ones and divide it by 7.
We know 7 × 1 = 7.
Write 1 in the ones place of the quotient and 7 bellow 7.
Subtract 7 from 7 to get 0.
Thus, 77 ÷ 7 = 11
II: Dividing a 2-digit Number by a 1-Digit Number with Remainder:
1. Divide the following and verify the result
76 ÷ 6
(a) 7 > 6, so 7T will be divided by 6,
6 one is 6, so 1T is quotient
(b) 7 – 6 = 1, 6 is carried down, so 16 will, be divided by 6.
6 twos are 12, 6 threes are 18, so quotient will be 2.
(c) 16 - 12 = 4 is the remainder
(d) 6 × 12 + 4 = 72 + 4 = 76 (dividend)
Therefore, result is verified.
The quotient = 12
Remainder = 4
2. Divide 89 by 4.
We proceed as follows:
Step I: Arrange the two given numbers as shown.
Step II: Divide the tens by 4.
Start by looking at the first number (tens place) in the dividend.
Find a number in the table of 4 less than or equal to 8
4 × 1 = 4,
4 × 2 = 8,
So, 2 is the required number.
4 × 2 = 8, write 2 in tens place of the quotient and 8 below 8.
Subtract the number you got by multiplying the divisor. from the number in the dividend.
Subtract 8 from 8 to get 0.
Step III: Divide the ones by 4.
Bring down the next digit (ones place), from the number in the dividend.
i.e., Bring down 9 ones and divide it by 4.
Repeat the same process again.
Find a number in the table of 4 less than or equal to 9
4 × 1 = 4,
4 × 2 = 8,
So, 2 is the required number.
4 × 2 = 8, write 2 in ones place of the quotient and 8 below 9.
Subtract 8 from 9 to get 1.
So, the quotient = 22 and remainder = 1.
3. Divide 66 by 5 and verify the result.
We proceed as follows:
Step I: Arrange the two given numbers.
Step II: Divide the tens by 5.
Start by looking at the first number (tens place) in the dividend.
Find a number in the table of 5 less than or equal to 6
5 × 1 = 5,
So, 1 is the required number.
5 × 1 = 5, write 1 in tens place of the quotient and 5 below 6.
Subtract the number you got by multiplying the divisor. from the number in the dividend.
Subtract 5 from 6 to get 1.
Step III: Bring down the next digit (ones place), from the number in the dividend.
i.e., Bring down 6 ones
The number is 16
Now and divide 16 by 5.
Repeat the same process again.
Find a number in the table of 5 less than or equal to 16
5 × 1 = 5,
5 × 2 = 10,
5 × 3 = 15,
So, 3 is the required number.
5 × 3 = 15, write 3 in ones place of the quotient and 15 below 16.
Subtract 15 from 16 to get 1.
So, the quotient = 13 and remainder = 1.
So, 66 is dividend,
5 is divisor,
3 is quotient,
1 is remainder.
Check: Dividend = Quotient × Divisor - Remainder
= 13 × 5 + 1
= 65 + 1
= 66 = Dividend
The same method is used when dividing larger numbers.
