A: Dividing a 2-digit Number by a 1-Digit Number without Remainder:

Division of Smaller Numbers

1. Let us divide 12 by 2.

Write 12 and 2 at the correct places as shown here.

Step I: Recall the table of the divisor 2 till you get the dividend 12.

1 × 2 = 2

2 × 2 = 4

3 × 2 = 6

4 × 2 = 8

5 × 2 = 10

6 × 2 = 12

Step II: Since 6 × 2 = 12 write 6 at the top and 12 below the dividend as shown.

Step III: Subtract 12 from 12. You will get 0.

So, 6 is the quotient.

2. 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

Note: Unlike in addition, subtraction or multiplication, we start from the tens place in division.

3. 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

B: Dividing a 2-digit Number by a 1-Digit Number with Remainder:

Division of Smaller Numbers

1. Let us now divide 14 by 3.

Write 14 and 3 at the correct places as shown.

Step I: Recall the table of the divisor 3, till you get the dividend 14.

1 × 3 = 3

2 × 3 = 6

3 × 3 = 9

4 × 3 = 12

5 × 3 = 15

Step II: We can see that 14 is not there in the table of 3. So, look for the number just smaller than 14 in the table. It is 12.

Step III: Since 4 × 3 = 12, write 4 at the top and 12 below the dividend.

Step IV: Subtract 12 from 14, you get 2.

Since 2 < 3 we cannot divide further.

So, 4 is the quotient and 2 is the remainder.

2. 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

3. 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.

4. 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.

Division of Greater Numbers:

In all the divisions of the previous section, the tens digit of the dividend is smaller than the divisor.

In this section, the tens digit of the dividend will either be equal to or greater than the divisor.

5. Let us divide 56 by 3.

Solution:

We see that the tens digit of the dividend '5' is greater than the divisor '3'.

Write 56 and 3 at the correct places.

Step I: Divide 5 tens by 3.

Recall the table of the divisor '3'. 1 × 3 = 3

5 tens ÷ 3 = 1 ten and 2 tens are left over.

Step II: Write 1 at the tens place of the quotient and 3 below 5 as shown.

Step III: Subtract 3 from 5, you get 2.

Step IV: Bring down the ones digit of the dividend '6'.

Divide 26 ones by 3.

Recall the table of the divisor 3'. 8 × 3 = 24

26 ones ÷ 3 = 8 ones and 2 ones are left over.

Step V: Write 8 at the ones place of the quotient and 24 below 26 as shown.

Step VI: Subtract 24 from 26, you get 2.

The quotient is 18 and the remainder is 2.

C. Word Problems on Dividing 2-Digit Number by 1-Digit Number 

1. Nairitee's father buys 68 hibiscus plants. She plants them in 2 equal rows. How many plants are there in each row?

Solution:

First, we arrange the numbers as shown.

Divisor →    2 $\overline{) 68 }$  ←  Dividend

Step I: If the first digit of the dividend is bigger than the divisor, then start dividing tens.

6 tens ÷ 2 = 3 tens.

Write 3 in the tens place of the quotient and subtract 2 × 3 = 6 from 6.

6 - 6 = 0.

Step II: Bring down the ones digit, 8 and then divide ones.

8 ones ÷ 2 = 4 ones,

Write 4 in the ones place of the quotient and subtract 2 × 4 = 8 from 8.

8 - 8 = 0.

So, she plants 34 hibiscus plants in each row.
