After division, all groups will have equal numbers of objects.
For example: Suppose we are given 15 squares and we need to make groups of 5 squares each.
Let's see how many groups can we make.
For this, we divide them in groups of 5 squares each.
There are 3 groups of 5.
So, the given 15 squares can be arranged in 3 groups of 5 squares each.
