Here we will show you step-by-step with detailed explanation how to calculate 312 divided by 3 using long division.

Before you continue, note that in the problem 312 divided by 3, the numbers are defined as follows:

**312 = dividend**

**3 = divisor**

**Step 1:**

Start by setting it up with the divisor 3 on the left side and the dividend 312 on the right side like this:

3 | ⟌ | 3 | 1 | 2 |

**Step 2:**

The divisor (3) goes into the first digit of the dividend (3), 1 time(s). Therefore, put 1 on top:

1 | ||||||

3 | ⟌ | 3 | 1 | 2 |

**Step 3:**

Multiply the divisor by the result in the previous step (3 x 1 = 3) and write that answer below the dividend.

1 | ||||||

3 | ⟌ | 3 | 1 | 2 | ||

3 |

**Step 4:**

Subtract the result in the previous step from the first digit of the dividend (3 - 3 = 0) and write the answer below.

1 | ||||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 |

**Step 5:**

Move down the 2nd digit of the dividend (1) like this:

1 | ||||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 |

**Step 6:**

The divisor (3) goes into the bottom number (1), 0 time(s). Therefore, put 0 on top:

1 | 0 | |||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 |

**Step 7:**

Multiply the divisor by the result in the previous step (3 x 0 = 0) and write that answer at the bottom:

1 | 0 | |||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 | |||||

0 |

**Step 8:**

Subtract the result in the previous step from the number written above it. (1 - 0 = 1) and write the answer at the bottom.

1 | 0 | |||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 | |||||

- | 0 | |||||

1 |

**Step 9:**

Move down the last digit of the dividend (2) like this:

1 | 0 | |||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 | |||||

- | 0 | |||||

1 | 2 |

**Step 10:**

The divisor (3) goes into the bottom number (12), 4 time(s). Therefore put 4 on top:

1 | 0 | 4 | ||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 | |||||

- | 0 | |||||

1 | 2 |

**Step 11:**

Multiply the divisor by the result in the previous step (3 x 4 = 12) and write the answer at the bottom:

1 | 0 | 4 | ||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 | |||||

- | 0 | |||||

1 | 2 | |||||

1 | 2 |

**Step 12:**

Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.

1 | 0 | 4 | ||||

3 | ⟌ | 3 | 1 | 2 | ||

- | 3 | |||||

0 | 1 | |||||

- | 0 | |||||

1 | 2 | |||||

- | 1 | 2 | ||||

0 |

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.
