Let's divide 20972239 by 871
We want to figure out the number of times 20972239 can be divided by 871.

Let's proceed to step 1:
2 divided by 871 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 871

Moving on to step 2:
871 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 871

On to step 3:
When dividing 209 by 871, we get 0 with a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 209 after subtracting 0 from 209.
Grab the next digit (7) from the dividend, add it to 209, then carry on: 2097 / 871

Step 4:
2097 divided by 871 is 2 with a remainder of 355.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1742 from 2097 leaves us with 355.
Grab the next digit (2) from the dividend, add it to 355, then carry on: 3552 / 871

Going ahead to step 5:
The number 871 fits into 3552 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 3484 from 3552 and we're left with 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 871

Let's proceed to step 6:
871 goes into 682 0 times with a remainder of 682.
The number 0 becomes the next digit in our result. 
Result so far: 240.0
Subtracting 0 from 682 leaves us with 682.
Fetch the next digit (3) from the dividend, attach it to 682 and continue: 6823 / 871

Step 7:
871 can be fit into 6823 7 times, resulting in a remainder of 726.
The number 7 becomes the next digit in our result. 
Result so far: 2407.0
Deduct 6097 from 6823 and we're left with 726.
Fetch the next digit (9) from the dividend, attach it to 726 and continue: 7269 / 871

Let's proceed to step 8:
871 can be fit into 7269 8 times, resulting in a remainder of 301.
Write down 8 as next digit of the result. 
Result so far: 24078.0
The remainder is 301 after subtracting 6968 from 7269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 9:
The number 871 fits into 3010 3 times, leaving a remainder of 397.
The next digit of our result is 3. 
Result so far: 24078.3
Subtracting 2613 from 3010 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 10:
If we divide 3970 by 871, we get 4 and a remainder of 486.
The number 4 becomes the next digit in our result. 
Result so far: 24078.34
If we subtract 3484 from 3970, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 11:
If we divide 4860 by 871, we get 5 and a remainder of 505.
The next digit of our result is 5. 
Result so far: 24078.345
Subtract 4355 from 4860 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 12:
871 can be fit into 5050 5 times, resulting in a remainder of 695.
Use 5 as the next digit of our solution. 
Result so far: 24078.3455
Subtracting 4355 from 5050 leaves us with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

The final result is 24078.3455 with a remainder of 0.00695.
