Let's divide 75384880 by 831
We want to divide 75384880 by 831.

On to step 1:
The number 831 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 831

Let's proceed to step 2:
If we divide 75 by 831, we get 0 and a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 831

Step 3:
831 goes into 753 0 times with a remainder of 753.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 753, we get 753.
Append the next digit (8) from the dividend to 753 and continue with: 7538 / 831

Let's proceed to step 4:
7538 divided by 831 is 9 with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7479 from 7538 to get 59.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 831

Step 5:
831 goes into 594 0 times with a remainder of 594.
Put 0 as the next digit of the answer. 
Result so far: 90.0
If we subtract 0 from 594, we get 594.
Append the next digit (8) from the dividend to 594 and continue with: 5948 / 831

Step 6:
The number 831 fits into 5948 7 times, leaving a remainder of 131.
Put 7 as the next digit of the answer. 
Result so far: 907.0
The remainder is 131 after subtracting 5817 from 5948.
Bring next digit (8) of the dividend behind the 131 and repeat the process: 1318 / 831

Let's proceed to step 7:
1318 divided by 831 is 1 with a remainder of 487.
The next digit of our result is 1. 
Result so far: 9071.0
If we take 831 away from 1318, we end up with 487.
Take the next digit (0) from the dividend and append it to 487, then repeat: 4870 / 831

On to step 8:
If we divide 4870 by 831, we get 5 and a remainder of 715.
The next digit of our result is 5. 
Result so far: 90715.0
The remainder is 715 after subtracting 4155 from 4870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Moving on to step 9:
If we divide 7150 by 831, we get 8 and a remainder of 502.
The next digit of our result is 8. 
Result so far: 90715.8
Subtract 6648 from 7150 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 10:
If we divide 5020 by 831, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 90715.86
Subtracting 4986 from 5020 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
When dividing 340 by 831, we get 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 90715.86
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 12:
831 can be fit into 3400 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 90715.8604
The remainder is 76 after subtracting 3324 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
The number 831 fits into 760 0 times, leaving a remainder of 760.
The next digit of our result is 0. 
Result so far: 90715.8604
If we subtract 0 from 760, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 14:
7600 divided by 831 is 9 with a remainder of 121.
Record the quotient 9 as the next digit in the result. 
Result so far: 90715.860409
Subtract 7479 from 7600 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 15:
The number 831 fits into 1210 1 times, leaving a remainder of 379.
Put 1 as the next digit of the answer. 
Result so far: 90715.8604091
Deduct 831 from 1210 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 16:
The number 831 fits into 3790 4 times, leaving a remainder of 466.
Write down 4 as next digit of the result. 
Result so far: 90715.86040914
If we take 3324 away from 3790, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

The final outcome is 90715.86040914, with a leftover of 4.66e-07.
