We look at the division of 51570785 by 831 
We want to figure out the number of times 51570785 can be divided by 831.

Step 1:
The number 831 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 831

Let's proceed to step 2:
831 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 831

Let's proceed to step 3:
831 can be fit into 515 0 times, resulting in a remainder of 515.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 515 to get 515.
Fetch the next digit (7) from the dividend, attach it to 515 and continue: 5157 / 831

Moving on to step 4:
5157 divided by 831 is 6 with a remainder of 171.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 4986 away from 5157, we end up with 171.
Take the next digit (0) from the dividend and append it to 171, then repeat: 1710 / 831

Going ahead to step 5:
The number 831 fits into 1710 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtracting 1662 from 1710 leaves us with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 831

Advancing to step 6:
831 goes into 487 0 times with a remainder of 487.
The number 0 becomes the next digit in our result. 
Result so far: 620.0
Subtract 0 from 487 to get 487.
Bring next digit (8) of the dividend behind the 487 and repeat the process: 4878 / 831

Moving on to step 7:
4878 divided by 831 is 5 with a remainder of 723.
Record the quotient 5 as the next digit in the result. 
Result so far: 6205.0
The remainder is 723 after subtracting 4155 from 4878.
Append the next digit (5) from the dividend to 723 and continue with: 7235 / 831

Advancing to step 8:
831 goes into 7235 8 times with a remainder of 587.
Put 8 as the next digit of the answer. 
Result so far: 62058.0
Deduct 6648 from 7235 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Advancing to step 9:
When dividing 5870 by 831, we get 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 62058.7
If we take 5817 away from 5870, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 10:
831 goes into 530 0 times with a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 62058.7
The remainder is 530 after subtracting 0 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 11:
The number 831 fits into 5300 6 times, leaving a remainder of 314.
Use 6 as the next digit of our solution. 
Result so far: 62058.706
Subtracting 4986 from 5300 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 12:
3140 divided by 831 is 3 with a remainder of 647.
Write down 3 as next digit of the result. 
Result so far: 62058.7063
Subtract 2493 from 3140 to get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Let's proceed to step 13:
When dividing 6470 by 831, we get 7 with a remainder of 653.
The number 7 becomes the next digit in our result. 
Result so far: 62058.70637
If we take 5817 away from 6470, we end up with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 14:
When dividing 6530 by 831, we get 7 with a remainder of 713.
Put 7 as the next digit of the answer. 
Result so far: 62058.706377
If we take 5817 away from 6530, we end up with 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

The final outcome is 62058.706377, with a leftover of 7.13e-05.
