75182215 ÷ 871 
We want to figure out the number of times 75182215 can be divided by 871.

On to step 1:
871 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 871

Step 2:
75 divided by 871 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 871

Advancing to step 3:
751 divided by 871 is 0 with a remainder of 751.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 751, we get 751.
Bring next digit (8) of the dividend behind the 751 and repeat the process: 7518 / 871

Moving on to step 4:
7518 divided by 871 is 8 with a remainder of 550.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 6968 from 7518, we get 550.
Grab the next digit (2) from the dividend, add it to 550, then carry on: 5502 / 871

Moving on to step 5:
If we divide 5502 by 871, we get 6 and a remainder of 276.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 276 after subtracting 5226 from 5502.
Bring next digit (2) of the dividend behind the 276 and repeat the process: 2762 / 871

Advancing to step 6:
When dividing 2762 by 871, we get 3 with a remainder of 149.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
Subtract 2613 from 2762 to get 149.
Append the next digit (1) from the dividend to 149 and continue with: 1491 / 871

On to step 7:
The number 871 fits into 1491 1 times, leaving a remainder of 620.
Write down 1 as next digit of the result. 
Result so far: 8631.0
Subtract 871 from 1491 to get 620.
Take the next digit (5) from the dividend and append it to 620, then repeat: 6205 / 871

Let's proceed to step 8:
When dividing 6205 by 871, we get 7 with a remainder of 108.
Record the quotient 7 as the next digit in the result. 
Result so far: 86317.0
Deduct 6097 from 6205 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
871 goes into 1080 1 times with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 86317.1
If we subtract 871 from 1080, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 10:
871 can be fit into 2090 2 times, resulting in a remainder of 348.
Write down 2 as next digit of the result. 
Result so far: 86317.12
Deduct 1742 from 2090 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 11:
871 can be fit into 3480 3 times, resulting in a remainder of 867.
Put 3 as the next digit of the answer. 
Result so far: 86317.123
The remainder is 867 after subtracting 2613 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8670, and continue the process.

Moving on to step 12:
If we divide 8670 by 871, we get 9 and a remainder of 831.
The next digit of our result is 9. 
Result so far: 86317.1239
The remainder is 831 after subtracting 7839 from 8670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8310, and continue the process.

Step 13:
The number 871 fits into 8310 9 times, leaving a remainder of 471.
Record the quotient 9 as the next digit in the result. 
Result so far: 86317.12399
If we subtract 7839 from 8310, we get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

The quotient of the division is 86317.12399, and the remainder is 0.000471.
