EXERCISE 6.3

1. Divide using the short division method.

(a) 7,894 ÷ 9 (b) 9,684 ÷ 12 (c) 2,075 ÷ 8 (d) 3,120 ÷ 10
2. Divide using both long and short division methods.

(a) 7,642 ÷ 8 (b) 6,873 ÷ 9 (c) 5,486 ÷ 13 (d) 7,048 ÷ 11

Division of a Number by 10, 100 and 1,000

• To divide a number by 10, write the ones digit of the number as remainder and the
other remaining digits as quotient.
For example, 8 2 6 ÷ 10

Quotient Remainder (ones digit)
(remaining digits)
Thus, the quotient is 82 and the remainder is 6.

• To divide a number by 100, write the number formed by the tens and ones digits as
remainder and the other remaining digits as quotient.
For example, 2 7 1 4 ÷ 100

Quotient Remainder (tens and ones digits)
(remaining digits)

Thus, the quotient is 27 and the remainder is 14.
