Let's divide 31618491 by 875
We want to figure out the number of times 31618491 can be divided by 875.

On to step 1:
875 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 875

Moving on to step 2:
The number 875 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 875

On to step 3:
If we divide 316 by 875, we get 0 and a remainder of 316.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 316, we end up with 316.
Fetch the next digit (1) from the dividend, attach it to 316 and continue: 3161 / 875

Going ahead to step 4:
If we divide 3161 by 875, we get 3 and a remainder of 536.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 2625 from 3161 to get 536.
Include the next digit (8) from the dividend after 536, then repeat: 5368 / 875

Step 5:
When dividing 5368 by 875, we get 6 with a remainder of 118.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 5250 from 5368 leaves us with 118.
Take the next digit (4) from the dividend and append it to 118, then repeat: 1184 / 875

Going ahead to step 6:
If we divide 1184 by 875, we get 1 and a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
The remainder is 309 after subtracting 875 from 1184.
Include the next digit (9) from the dividend after 309, then repeat: 3099 / 875

On to step 7:
875 goes into 3099 3 times with a remainder of 474.
Write down 3 as next digit of the result. 
Result so far: 3613.0
Subtracting 2625 from 3099 leaves us with 474.
Append the next digit (1) from the dividend to 474 and continue with: 4741 / 875

Going ahead to step 8:
When dividing 4741 by 875, we get 5 with a remainder of 366.
The number 5 becomes the next digit in our result. 
Result so far: 36135.0
If we subtract 4375 from 4741, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 9:
875 goes into 3660 4 times with a remainder of 160.
The next digit of our result is 4. 
Result so far: 36135.4
If we subtract 3500 from 3660, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
1600 divided by 875 is 1 with a remainder of 725.
Use 1 as the next digit of our solution. 
Result so far: 36135.41
Subtract 875 from 1600 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Going ahead to step 11:
875 goes into 7250 8 times with a remainder of 250.
The next digit of our result is 8. 
Result so far: 36135.418
Subtract 7000 from 7250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
2500 divided by 875 is 2 with a remainder of 750.
Write down 2 as next digit of the result. 
Result so far: 36135.4182
Subtract 1750 from 2500 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 13:
The number 875 fits into 7500 8 times, leaving a remainder of 500.
The number 8 becomes the next digit in our result. 
Result so far: 36135.41828
If we take 7000 away from 7500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 14:
875 goes into 5000 5 times with a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 36135.418285
If we subtract 4375 from 5000, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Step 15:
6250 divided by 875 is 7 with a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 36135.4182857
Subtract 6125 from 6250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 16:
875 goes into 1250 1 times with a remainder of 375.
The number 1 becomes the next digit in our result. 
Result so far: 36135.41828571
Deduct 875 from 1250 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

After the division, we end up with 36135.41828571 and a remainder of 3.75e-07.
