Okay so the first thing we need to do is clarify the terms so that you know what each part of the division is:

The first number, 420, is called the dividend.
The second number, 21 is called the divisor.

What we'll do here is break down each step of the long division process for 420 divided by 21 and explain each of them so you understand exactly what is going on.

420 divided by 21 step-by-step guide

Step 1

The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:

Step 2

We can work out that the divisor (21) goes into the first digit of the dividend (4), 0 time(s). Now we know that, we can put 0 at the top:

			0
2	1		4	2	0

Step 3

If we multiply the divisor by the result in the previous step (21 x 0 = 0), we can now add that answer below the dividend:

		0
2	1	4	2	0
		0

Step 4

Next, we will subtract the result from the previous step from the second digit of the dividend (4 - 0 = 4) and write that answer below:

			0
2	1		4	2	0
		-	0
			4

Step 5

Move the second digit of the dividend (2) down like so:

			0
2	1		4	2	0
		-	0
			4	2

Step 6

The divisor (21) goes into the bottom number (42), 2 time(s), so we can put 2 on top:

			0	2
2	1		4	2	0
		-	0
			4	2

Step 7

If we multiply the divisor by the result in the previous step (21 x 2 = 42), we can now add that answer below the dividend:

			0	2
2	1		4	2	0
		-	0
			4	2
			4	2

Step 8

Next, we will subtract the result from the previous step from the third digit of the dividend (42 - 42 = 0) and write that answer below:

			0	2
2	1		4	2	0
		-	0
			4	2
		-	4	2
				0

Step 9

Move the third digit of the dividend (0) down like so:

			0	2
2	1		4	2	0
		-	0
			4	2
		-	4	2
					0

Step 10

The divisor (21) goes into the bottom number (0), 0 time(s), so we can put 0 on top:

			0	2	0
2	1		4	2	0
		-	0
			4	2
		-	4	2
					0

Step 11

If we multiply the divisor by the result in the previous step (21 x 0 = 0), we can now add that answer below the dividend:

			0	2	0
2	1		4	2	0
		-	0
			4	2
		-	4	2
					0
					0

Step 12

Next, we will subtract the result from the previous step from the fourth digit of the dividend (0 - 0 = 0) and write that answer below:

			0	2	0
2	1		4	2	0
		-	0
			4	2
		-	4	2
					0
		-			0
					0

So, what is the answer to 420 divided by 21?

If you made it this far into the tutorial, well done! There are no more digits to move down from the dividend, which means we have completed the long division problem.

Your answer is the top number, and any remainder will be the bottom number. So, for 420 divided by 21, the final solution is:

Remainder 0
