Exercise 4B

1. Find the quotient and the remainder. Check your answer.
a. 204 ÷ 4 b. 108 ÷ 5 c. 568 ÷ 2 d. 736 ÷ 9
e. 465 ÷ 5 f. 665 ÷ 7 g. 477 ÷ 9 h. 816 ÷ 6

2. Divide and check your answer.
a. 308 ÷ 3 b. 724 ÷ 8 c. 654 ÷ 5 d. 478 ÷ 9
e. 841 ÷ 4 f. 423 ÷ 5 g. 760 ÷ 7 h. 536 ÷ 5
i. 7536 ÷ 6 j. 5476 ÷ 8 k. 2396 ÷ 7 l. 2095 ÷ 2
m. 8303 ÷ 4 n. 1597 ÷ 6 o. 7649 ÷ 9 p. 8311 ÷ 5
3. Divide the following:

a. 7548 ÷ 4 b. 2416 ÷ 6 c. 1957 ÷ 6 d. 8437 ÷ 8
e. 2059 ÷ 3 f. 2648 ÷ 4 g. 3153 ÷ 3 h. 7585 ÷ 6
4. Find the remainder for the following: Use Remainder = Dividend - (Quotient × Divisor).

a. Quotient = 124, Divisor = 8, Dividend = 999
b. Quotient = 809, Divisor = 6, Dividend = 4858
c. Quotient = 568, Divisor = 5, Dividend = 2843
d. Quotient = 914, Divisor = 9, Dividend = 8234

Division by a 2-Digit DivisoR

Dividing a 2-digit number

Division by a 2-digit divisor can be done in the same way as division by a 1-digit
divisor. However, in this kind of division, multiplication tables help us.

Example 1. Find 72 ÷ 16. 4 Q

solution. 16 7 2
step 1. 7 < 16, so take 72 as the dividend and divide it by 16. – 6 4

step 2. Recite the multiplication table of 16. 8 R
4 × 16 = 64 and 5 × 16 = 80

As 80 > 72 > 64, write 4 in the ones place of the quotient and 64 below 72.
step 3. Subtract 64 from 72. We have 72 – 64 = 8 as the remainder.
So, Q = 4, R = 8.

Checking: Quotient × Divisor + Remainder = Dividend
4 × 16 + 8 = 72
64 + 8 = 72
Therefore, the division is correct.
