**How do you do DivisionĀ on a calculator?**

With multiplication, the order in which you multiply does not matter, but with division, it can often be critical. So if you get stuck in the examples and practice problems, try punching them your calculator buttons in a different order to see if that makes any difference.

**Examples**: These are the ways division can be written. I demonstrate how these examples are put into your calculator with these two different links. **VIDEO Division examples with a regular calculator. VIDEO Division with a graphing calculator**.

16 divided by 4 = | 4 |

3 divided into 9 = | 3 |

10 / 5 = | 2 |

In text I will tend to write division like below

45 = | 9 |

5 |

63 = | 21 |

3 |

28 = | 0.28 |

100 |

**PRACTICE PROBLEMS**: Solve these division problems.

5 divided into 20 = | 4 |

6 divided by 12 = | 0.5 |

30 / 6 = | 5 |

40 divided into 10 = | 0.25 |

3/9 = | 0.33 |

60 / 15 = | 4 |

12 = | 4 |

3 |

74 = | 37 |

2 |

16 = | 0.32 |

50 |
