Facts about Division
We have already learned division by repeated subtraction, equal sharing/distribution and by short division method. Now, we will read some facts about division to learn long division.
1. If the dividend is ‘zero’ then any number as a divisor will give the quotient as ‘zero’.
Example: If ‘zero’ sweets are to be distributed among 8 children, naturally no one will get any sweets.
2. If the divisor is ‘1’ then any dividend will have the quotient equal to itself.
Example: There are 15 sweets; each child is to get 1 sweet. How many children get the sweets?
3. The product of the divisor and the quotient added to the remainder is always equal to the dividend.
(Divisor × Quotient) + Remainder = Dividend.
(d × q) + r = D
Note:
Always find the product first and then add the remainder. (This helps us to
check whether the division is done correct or not.)
Example: Divide 23 by 7
Checking:
(d × q) + r = D
(7 × 3) + 2 = 23
21 + 2 = 23
23 = 23
So, the division is correct.
4. In a division sum the remainder is always smaller than
the divisor.
Example:
In the last example clearly we can see that the remainder
(2) is less than the divisor (7).
5. Every divisor fact has two multiplication facts to verify
it.
Example:
In division, 12 ÷ 6 = 2, two multiplication facts
are 2 × 6 = 12 and 6 × 2 = 12.
6. The quotient and the divisor are always the factors of
the dividend, if there is no remainder.
Example:
7. The dividend is always a multiple of the quotient and
divisor, if there is no remainder.
Example:
D 30 5 6

÷ × ×

d 5 6 5

= = =

q 6 30 30

Let us have a quick review of what we have
learnt about division. Division is splitting into equal parts or groups. It is
the result of “fair sharing”.
If 5 friends want to share 15 chocolates.
How many chocolates will each of them get? Let us divide the chocolates equally
amongst them.
15 divided by 5 is 3. They get 3 each.
