Example 4: Delhi Jal Board supplied 978795 litres of water in a colony which had 375
families. How much water did each family get if each family got same amount of water and
how much water was left?
Solution: Total quantity of water supplied = 978795 litres 2 6 1 0 Q

9 7 8 7 9 5
Total number of families = 375 375 7 5 0
Quantity of water each family got = (978795 ÷ 375) litres 2 2 8 7

Thus, each family of the colony got 2610 litres of water 2 2 5 0

and 45 litres of water was left. 3 7 5

Example 5: The cost of 125 radio sets is `104500. What is the cost of one radio?

Solution: Cost of 125 radio sets = `104500 8 3 6 Q
1 0 4 5 0 0
Cost of 1 radio set = `104500 ÷ 125 = `836 125 1 0 0 0
Thus, the cost of one radio set is `836. 4 5 0
– 3 7 5

Properties of Division

1. When a number is divided by itself, the quotient is 1.

Example: (a) 36 ÷ 36 = 1 (b) 239 ÷ 239 = 1
2. When a number is divided by 1, the quotient is the number itself.
Example: (a) 37 ÷ 1 = 37 (b) 325 ÷ 1 = 325

3. When 0 is divided by a non-zero number, the quotient is zero.
Example: (a) 0 ÷ 44 = 0 (b) 0 ÷ 365 = 0
4. Division by 0 is meaningless.

1. Find the quotient and remainder and check your answer.
(a) 275736 ÷ 9 (b) 876048 ÷ 7 (c) 683396 ÷ 15 (d) 436263 ÷ 23

(e) 804009 ÷ 78 (f) 183648 ÷ 143 (g) 728804 ÷ 192 (h) 355444 ÷ 222
2. Find the dividend, if

(a) divisor = 136, quotient = 75 and remainder = 31
(b) divisor = 403, quotient = 801 and remainder = 325
