The videos in this lesson will teach you how to do division with multiple digits. This process is applicable for numbers that divide evenly, and those with decimal answers. The videos in this lesson demonstrate one way to do division. If you are familiar with another algorithm or pattern, you are welcome to use it. The important thing is to understand what you are doing and why so you can apply it to real-world situations.
Steps for Division:
- Put the number being divided (the dividend) under the box and the other number (the divisor) to the left of the box.
- Starting on the left, determine how many times the divisor can go into the first digit of the dividend.
- Write that number above the digit and subtract the product of that number and the divisor from the dividend.
- Repeat steps 2 and 3, moving to the right.
The following video will walk through these steps in a couple of examples.

The same process of division is used, even when we get a decimal answer. Remember, we can always add 0’s after the decimal place on a number (for example: 2 = 2.0 = 2.00). The following video will show how to divide with decimals.

Once again, you may find yourself going slowly through this process. That’s alright. To help yourself speed up, try studying and memorizing your 1-digit multiplication facts. Knowing these will help you as you follow the division steps.
