We're dividing 57271929 by 831 
Let's see how many times 831 fits into 57271929.

Step 1:
If we divide 5 by 831, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 831

Moving on to step 2:
If we divide 57 by 831, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 831

Let's proceed to step 3:
If we divide 572 by 831, we get 0 and a remainder of 572.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 572 leaves us with 572.
Take the next digit (7) from the dividend and append it to 572, then repeat: 5727 / 831

Going ahead to step 4:
831 can be fit into 5727 6 times, resulting in a remainder of 741.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 4986 away from 5727, we end up with 741.
Append the next digit (1) from the dividend to 741 and continue with: 7411 / 831

On to step 5:
831 goes into 7411 8 times with a remainder of 763.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Subtract 6648 from 7411 to get 763.
Include the next digit (9) from the dividend after 763, then repeat: 7639 / 831

Step 6:
831 can be fit into 7639 9 times, resulting in a remainder of 160.
The number 9 becomes the next digit in our result. 
Result so far: 689.0
If we subtract 7479 from 7639, we get 160.
Bring next digit (2) of the dividend behind the 160 and repeat the process: 1602 / 831

Step 7:
831 goes into 1602 1 times with a remainder of 771.
Put 1 as the next digit of the answer. 
Result so far: 6891.0
Deduct 831 from 1602 and we're left with 771.
Bring next digit (9) of the dividend behind the 771 and repeat the process: 7719 / 831

Moving on to step 8:
If we divide 7719 by 831, we get 9 and a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 68919.0
The remainder is 240 after subtracting 7479 from 7719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 9:
The number 831 fits into 2400 2 times, leaving a remainder of 738.
The next digit of our result is 2. 
Result so far: 68919.2
Deduct 1662 from 2400 and we're left with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

On to step 10:
831 goes into 7380 8 times with a remainder of 732.
Write down 8 as next digit of the result. 
Result so far: 68919.28
Subtract 6648 from 7380 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Moving on to step 11:
831 can be fit into 7320 8 times, resulting in a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 68919.288
Deduct 6648 from 7320 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

After the division, we end up with 68919.288 and a remainder of 0.0672.
