8721 divided by 22 
We're looking to find how many times 22 goes into 8721.

On to step 1:
The number 22 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 22

Moving on to step 2:
If we divide 87 by 22, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 21 after subtracting 66 from 87.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 22

Moving on to step 3:
When dividing 212 by 22, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 198 away from 212, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 22

Let's proceed to step 4:
22 goes into 141 6 times with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 396.0
The remainder is 9 after subtracting 132 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 5:
If we divide 90 by 22, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 396.4
Subtracting 88 from 90 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
If we divide 20 by 22, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 396.4
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 22, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 396.409
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
22 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 396.409
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 22 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 396.40909
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
The number 22 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 396.40909
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 396.4090909
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
22 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 396.4090909
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 396.4090909 with a remaining 2e-08.
