Let's divide 873722 by 21
Let's see how many times 21 fits into 873722.

Advancing to step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 21

On to step 2:
21 can be fit into 87 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 84 from 87, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 21

Going ahead to step 3:
When dividing 33 by 21, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we subtract 21 from 33, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 21

Step 4:
21 goes into 127 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 416.0
If we subtract 126 from 127, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 21

Going ahead to step 5:
21 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 4160.0
Subtract 0 from 12 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 21

On to step 6:
21 goes into 122 5 times with a remainder of 17.
The next digit of our result is 5. 
Result so far: 41605.0
Subtract 105 from 122 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 41605.8
Subtract 168 from 170 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.

Moving on to step 8:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 41605.8
Deduct 0 from 20 and we're left 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.

Going ahead to step 9:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 41605.809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 21 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 41605.8095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
21 goes into 50 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 41605.80952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 41605.809523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 41605.8095238
Subtracting 168 from 170 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.

Step 14:
21 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 41605.8095238
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.

The final result is 41605.8095238 with a remainder of 2e-08.
