57216666 divided by 831 
We want to divide 57216666 by 831.

Step 1:
5 divided by 831 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 831

Let's proceed to step 2:
57 divided by 831 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 831

Moving on to step 3:
572 divided by 831 is 0 with a remainder of 572.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 572 and we're left with 572.
Include the next digit (1) from the dividend after 572, then repeat: 5721 / 831

Going ahead to step 4:
If we divide 5721 by 831, we get 6 and a remainder of 735.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 735 after subtracting 4986 from 5721.
Append the next digit (6) from the dividend to 735 and continue with: 7356 / 831

Going ahead to step 5:
831 goes into 7356 8 times with a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtract 6648 from 7356 to get 708.
Grab the next digit (6) from the dividend, add it to 708, then carry on: 7086 / 831

Moving on to step 6:
The number 831 fits into 7086 8 times, leaving a remainder of 438.
Record the quotient 8 as the next digit in the result. 
Result so far: 688.0
Deduct 6648 from 7086 and we're left with 438.
Bring next digit (6) of the dividend behind the 438 and repeat the process: 4386 / 831

Going ahead to step 7:
The number 831 fits into 4386 5 times, leaving a remainder of 231.
The number 5 becomes the next digit in our result. 
Result so far: 6885.0
Deduct 4155 from 4386 and we're left with 231.
Grab the next digit (6) from the dividend, add it to 231, then carry on: 2316 / 831

Moving on to step 8:
If we divide 2316 by 831, we get 2 and a remainder of 654.
The number 2 becomes the next digit in our result. 
Result so far: 68852.0
If we take 1662 away from 2316, we end up with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 9:
831 goes into 6540 7 times with a remainder of 723.
Write down 7 as next digit of the result. 
Result so far: 68852.7
Deduct 5817 from 6540 and we're left with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 10:
831 goes into 7230 8 times with a remainder of 582.
Put 8 as the next digit of the answer. 
Result so far: 68852.78
The remainder is 582 after subtracting 6648 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 11:
If we divide 5820 by 831, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 68852.787
The remainder is 3 after subtracting 5817 from 5820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
When dividing 30 by 831, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 68852.787
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
831 goes into 300 0 times with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 68852.787
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 68852.787 with a balance of 0.0003.
