We're dividing 58108378 by 831 
We want to divide 58108378 by 831.

Advancing to step 1:
When dividing 5 by 831, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 831

Moving on to step 2:
831 can be fit into 58 0 times, resulting in a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 831

Going ahead to step 3:
The number 831 fits into 581 0 times, leaving a remainder of 581.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 581, we get 581.
Include the next digit (0) from the dividend after 581, then repeat: 5810 / 831

Going ahead to step 4:
831 can be fit into 5810 6 times, resulting in a remainder of 824.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 4986 from 5810 leaves us with 824.
Grab the next digit (8) from the dividend, add it to 824, then carry on: 8248 / 831

On to step 5:
831 can be fit into 8248 9 times, resulting in a remainder of 769.
Put 9 as the next digit of the answer. 
Result so far: 69.0
The remainder is 769 after subtracting 7479 from 8248.
Bring next digit (3) of the dividend behind the 769 and repeat the process: 7693 / 831

Moving on to step 6:
831 goes into 7693 9 times with a remainder of 214.
Use 9 as the next digit of our solution. 
Result so far: 699.0
Subtracting 7479 from 7693 leaves us with 214.
Bring next digit (7) of the dividend behind the 214 and repeat the process: 2147 / 831

Moving on to step 7:
2147 divided by 831 is 2 with a remainder of 485.
Write down 2 as next digit of the result. 
Result so far: 6992.0
If we take 1662 away from 2147, we end up with 485.
Include the next digit (8) from the dividend after 485, then repeat: 4858 / 831

Step 8:
When dividing 4858 by 831, we get 5 with a remainder of 703.
Write down 5 as next digit of the result. 
Result so far: 69925.0
Deduct 4155 from 4858 and we're left with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Moving on to step 9:
The number 831 fits into 7030 8 times, leaving a remainder of 382.
The number 8 becomes the next digit in our result. 
Result so far: 69925.8
If we take 6648 away from 7030, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 10:
3820 divided by 831 is 4 with a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 69925.84
Deduct 3324 from 3820 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 11:
831 goes into 4960 5 times with a remainder of 805.
Write down 5 as next digit of the result. 
Result so far: 69925.845
If we subtract 4155 from 4960, we get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 12:
831 goes into 8050 9 times with a remainder of 571.
Put 9 as the next digit of the answer. 
Result so far: 69925.8459
Subtract 7479 from 8050 to get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Going ahead to step 13:
831 goes into 5710 6 times with a remainder of 724.
Record the quotient 6 as the next digit in the result. 
Result so far: 69925.84596
Deduct 4986 from 5710 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 14:
831 can be fit into 7240 8 times, resulting in a remainder of 592.
The number 8 becomes the next digit in our result. 
Result so far: 69925.845968
If we subtract 6648 from 7240, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 15:
831 goes into 5920 7 times with a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 69925.8459687
If we subtract 5817 from 5920, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 16:
When dividing 1030 by 831, we get 1 with a remainder of 199.
The next digit of our result is 1. 
Result so far: 69925.84596871
If we take 831 away from 1030, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

The final outcome is 69925.84596871, with a leftover of 1.99e-07.
