1. Divide the following and check your answers.

(a) 3092 ÷ 11 (b) 2974 ÷ 14 (c) 6501 ÷ 12 (d) 1564 ÷ 23
(e) 3039 ÷ 32 (f) 23709 ÷ 18 (g) 3274 ÷ 29 (h) 7756 ÷ 20

2. Find the quotient and the remainder.

(a) 7256 ÷ 12 (b) 5872 ÷ 18 (c) 3897 ÷ 63 (d) 8775 ÷ 21
(e) 25284 ÷ 14 (f) 29045 ÷ 28 (g) 13207 ÷ 17 (h) 28700 ÷ 26

3. Which number will give the smallest quotient when divided by 17?

Division by 10, 100 anD 1000

Division by 10

Example 1: Divide the following.

(a) 92 ÷ 10 (b) 573 ÷ 10 (c) 2438 ÷ 10

Solution:
(a) 10 92 9 (b) 10 573 57 (c) 10 2438 243
– 90 – 50 – 20

2 73 43
– 70 – 40
Q = 9, R = 2
3 38
– 30
Q = 57, R = 3
8

Q = 243, R = 8
Alternatively,

(a) (b) (c)
t O H t O th H t O
9 2 ÷ 10 = 9 R 2 5 7 3 ÷ 10 = 57 R 3 2 4 3 8 ÷ 10 = 243 R 8

Therefore, when a number is divided by 10, the digit in the ones place is the remainder
and the remaining digit(s) form the quotient.

Division by 100

Example 2: Divide the following.
(a) 876 ÷ 100 (b) 3438 ÷ 100 (c) 65032 ÷ 100
