In this exercise, we will look at
the **long-division** method. The long-division method is used when we wish to divide a big number, say 2145 by a smaller number, say 5.

**Note, you should have mastered the multiplication tables before you attempt this exercise.**

The long-division method is done in several steps:

- Divide a portion of the dividend by the divisor, as detailed in the example below.
- Multiply.
- Subtract.
- Bring down the remaining digit and repeat from the first step until we have finished all the digits of the divident.

Let us see the long-division method in an example. Let us say we want to divide 81 candies into 3 friends. We would write the problem as:

Now, since the first digit of the divident (81) is smaller than the divisor (3), we would calculate 8 ÷ 3. Think of this as if you had 8 candies and you want to divide them amongst 3 friends. So, each friend would get 2 candies. This is the first step:

Step 1.Find the largest number that will divide the first digit of the divident. | |

Step 2. Next, we multiply the quotient from the previous step with the divisor and write it like this. | |

Step 3. Subtract | |

Step 4. Bring next digit of the dividend down | |

Step 5. Repeat all the steps above until you cant divide any more. If we combine all the steps into one step, we have: | |

Step 6. So, the final answer is 27 |

So, the final answer of 81 ÷ 3 is 27.
