17128208 ÷ 871 
We want to figure out the number of times 17128208 can be divided by 871.

Step 1:
When dividing 1 by 871, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 871

Let's proceed to step 2:
If we divide 17 by 871, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 871

On to step 3:
171 divided by 871 is 0 with a remainder of 171.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 171 to get 171.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 871

Advancing to step 4:
1712 divided by 871 is 1 with a remainder of 841.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 841 after subtracting 871 from 1712.
Take the next digit (8) from the dividend and append it to 841, then repeat: 8418 / 871

Step 5:
871 goes into 8418 9 times with a remainder of 579.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 7839 from 8418 and we're left with 579.
Take the next digit (2) from the dividend and append it to 579, then repeat: 5792 / 871

Moving on to step 6:
If we divide 5792 by 871, we get 6 and a remainder of 566.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
Subtracting 5226 from 5792 leaves us with 566.
Fetch the next digit (0) from the dividend, attach it to 566 and continue: 5660 / 871

On to step 7:
The number 871 fits into 5660 6 times, leaving a remainder of 434.
Record the quotient 6 as the next digit in the result. 
Result so far: 1966.0
Subtracting 5226 from 5660 leaves us with 434.
Take the next digit (8) from the dividend and append it to 434, then repeat: 4348 / 871

Let's proceed to step 8:
4348 divided by 871 is 4 with a remainder of 864.
The number 4 becomes the next digit in our result. 
Result so far: 19664.0
Deduct 3484 from 4348 and we're left with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

On to step 9:
When dividing 8640 by 871, we get 9 with a remainder of 801.
Use 9 as the next digit of our solution. 
Result so far: 19664.9
If we subtract 7839 from 8640, we get 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

On to step 10:
The number 871 fits into 8010 9 times, leaving a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 19664.99
If we take 7839 away from 8010, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

The quotient of the division is 19664.99, and the remainder is 0.171.
