We're dividing 21728865 by 871 
We want to figure out the number of times 21728865 can be divided by 871.

Going ahead to step 1:
871 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 871

Advancing to step 2:
The number 871 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 871

On to step 3:
The number 871 fits into 217 0 times, leaving a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 217, we end up with 217.
Fetch the next digit (2) from the dividend, attach it to 217 and continue: 2172 / 871

Step 4:
871 can be fit into 2172 2 times, resulting in a remainder of 430.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1742 away from 2172, we end up with 430.
Fetch the next digit (8) from the dividend, attach it to 430 and continue: 4308 / 871

Let's proceed to step 5:
If we divide 4308 by 871, we get 4 and a remainder of 824.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 824 after subtracting 3484 from 4308.
Grab the next digit (8) from the dividend, add it to 824, then carry on: 8248 / 871

Going ahead to step 6:
When dividing 8248 by 871, we get 9 with a remainder of 409.
Use 9 as the next digit of our solution. 
Result so far: 249.0
Deduct 7839 from 8248 and we're left with 409.
Take the next digit (6) from the dividend and append it to 409, then repeat: 4096 / 871

Step 7:
4096 divided by 871 is 4 with a remainder of 612.
The number 4 becomes the next digit in our result. 
Result so far: 2494.0
If we subtract 3484 from 4096, we get 612.
Append the next digit (5) from the dividend to 612 and continue with: 6125 / 871

Step 8:
The number 871 fits into 6125 7 times, leaving a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 24947.0
Subtracting 6097 from 6125 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 871 is 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 24947.0
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 10:
2800 divided by 871 is 3 with a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 24947.03
If we take 2613 away from 2800, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 11:
The number 871 fits into 1870 2 times, leaving a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 24947.032
Subtracting 1742 from 1870 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 12:
1280 divided by 871 is 1 with a remainder of 409.
Record the quotient 1 as the next digit in the result. 
Result so far: 24947.0321
Deduct 871 from 1280 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 13:
4090 divided by 871 is 4 with a remainder of 606.
Use 4 as the next digit of our solution. 
Result so far: 24947.03214
The remainder is 606 after subtracting 3484 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 14:
871 can be fit into 6060 6 times, resulting in a remainder of 834.
Write down 6 as next digit of the result. 
Result so far: 24947.032146
If we take 5226 away from 6060, we end up with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Let's proceed to step 15:
The number 871 fits into 8340 9 times, leaving a remainder of 501.
Write down 9 as next digit of the result. 
Result so far: 24947.0321469
If we subtract 7839 from 8340, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 16:
When dividing 5010 by 871, we get 5 with a remainder of 655.
Record the quotient 5 as the next digit in the result. 
Result so far: 24947.03214695
If we take 4355 away from 5010, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

The quotient of the division is 24947.03214695, and the remainder is 6.55e-07.
