So, in the above process where we divided 16 balls into 4 equal groups;
The dividend is 16, the divisor is 4 and thus the quotient is 4.
Introduction to the remainder
The remainder is the portion of the dividend that is left over after division. For
example, on dividing 83 by 2, there is a leftover of 1.
It means, 83 ÷ 2 = 41 and r =1,
Here, ‘r’ is remainder.
One more way of explaining given problem is that if there are 6 groups each
having equal number of items and the total number of items is 42, then number
of items in each group is given by;
42 ÷ 6 = 7
For every group of three numbers, there will be two multiplication facts and two
division facts.
Memorizing such math facts and multiplication tables helps in solving division
and multiplication problems.
For example the multiplication and division facts for numbers 40, 5 and 8 are as
follows:
5 × 8 = 40
8 × 5 = 40
40 ÷ 8 = 5
40 ÷ 5 = 8
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.
0 ÷ 8 = 0
0 ÷ any no. = 0
Division by 0 is undefined. Any number ÷ 0 = not defined
The division of the same dividend and divisor is always 1. For example: 4 ÷ 4 =
1.
If the divisor is ‘1’ then any dividend will have the quotient equal to itself.
There are 15 sweets; each child is to get 1 sweet. How many children get the
sweets?
