## Dividing by 10

A decimal point comes after a whole number e.g. 2.1 - the number two is a whole number.

Move the decimal point one place to the left.

## Example 1

2 ÷ 10 = ?

Before | ||||
---|---|---|---|---|

Th | H | T | U | 1/10 |

2 |

After | ||||
---|---|---|---|---|

Th | H | T | U | 1/10 |

2 |

Answer= 0.2

## Example 2

30 ÷ 10 = ?

Before | ||||
---|---|---|---|---|

Th | H | T | U | 1/10 |

3 | 0 |

After | ||||
---|---|---|---|---|

Th | H | T | U | 1/10 |

3 | 0 |

Answer= 3

## Dividing by 100

Move the decimal point two places to the left.

## Example 1

750 ÷ 100 = ?

Before | |||||
---|---|---|---|---|---|

Th | H | T | U | 1/10 | 1/100 |

7 | 5 | 0 |

After | |||||
---|---|---|---|---|---|

Th | H | T | U | 1/10 | 1/100 |

7 | 5 | 0 |

Answer= 7.5

## Dividing by 1000

Move the decimal point three places to the left.

4000 ÷ 1000 = ?

Before | ||||||
---|---|---|---|---|---|---|

Th | H | T | U | 1/10 | 1/100 | 1/1000 |

4 | 0 | 0 | 0 |

After | ||||||
---|---|---|---|---|---|---|

Th | H | T | U | 1/10 | 1/100 | 1/1000 |

4 | 0 | 0 | 0 |

Answer= 4

# Dividing Numbers

If you know your times tables the following divisions will be easy for you to calculate:

## Example 1

42 ÷ 7 = ?

We know 6 x 7 = 42.

Therefore 42 ÷ 7 = 6.

## Example 2

32 ÷ 8 = ?

We know 4 x 8 = 32.

Therefore 32 ÷ 8 = 4.

## Example 3

25 ÷ 5 = ?

We know 5 x 5 = 25.

Therefore 25 ÷ 5 = 5.

# Graphical Items

Let's have a look at graphical items.

## Example 1

If you have nine balls and three people. How many balls would

each person have?

## Example 2

If you have 4 presents and two people. How many presents would each person have?

# Division with Remainders

In division you have one or more remainders left.

## Example 1

42 ÷ 3 = ?

- 4 ÷ 3 = 1 plus 1 remainder
- Carry the remainder 1.
- 12 ÷ 3 = 4

Answer:14

## Example 2

95 ÷ 5= ?

- 9 ÷ 5 = 1 plus 4 remainders
- Carry the 4 remainders.
- 45 ÷ 5 = 9

Answer:19

You could use the long division method to calculate your answer.

## Example 3

66 ÷ 12 = ?

- You know 12 x 5= 60 so 66 ÷ 12 = 5 plus 6 remainders.
- Add a decimal point after the 5.
- After the 6 remainders add a 0.
- 60 ÷ 12 = 5

Answer: 5.5
