Example : 85 sweets were distributed among 15 children. How many
sweets did each child get ? How many sweets were left over ?

Solution : 85 ÷ 15 = ?

Step 1 : First estimate the quotient.

15 85 rounds to 20 100

To solve this we think of 10 ÷ 2

The estimated quotient is 5.

Step 2 : Let us try the estimated quotient.

15 × 6 = 90

90 > 85

So, try another smaller number.

15 × 5 = 75

75 < 85, so take 5 as the quotient because it is smaller and

closest to the dividend.

Step 3 : Divide :

5 Checking :

15 85 15 × 5 + 10 = 85
– 75

10 Quotient = 5, Remainder = 10

Thus, each child got 5 sweets. There were 10 sweets left over.
