Numbers: Getting to grips with division

1 Ways of expressing division

Division is the opposite of multiplication. If you say:

  • What do I get if I divide 20 by 4?

It is equivalent to saying:

  • What do I have to multiply 4 by to get 20?

Division can be expressed in various ways. You can say:

  • divided by – as in ‘8 divided by 4’
  • over – as in ‘8 over 4’
  • divided between – as in ‘8 apples divided equally between 4 people’.

It can also be expressed as how many times one number ‘goes into’ another. As you will see below, this is similar to wording the division as if it were a multiplication.

So the following expressions all mean the same thing:

  • What do I get if I divide 20 by 4?
  • What is 20 over 4?
  • What do I have to multiply 4 by to get 20?
  • How many times does 4 go into 20?

Division calculations can also be represented in several different ways. All of the following mean 20 divided by 4:
