55700591 ÷ 831 
We want to divide 55700591 by 831.

Step 1:
831 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 831

Going ahead to step 2:
831 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 831

Moving on to step 3:
831 goes into 557 0 times with a remainder of 557.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 557, we get 557.
Include the next digit (0) from the dividend after 557, then repeat: 5570 / 831

Advancing to step 4:
831 can be fit into 5570 6 times, resulting in a remainder of 584.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 4986 away from 5570, we end up with 584.
Fetch the next digit (0) from the dividend, attach it to 584 and continue: 5840 / 831

Going ahead to step 5:
If we divide 5840 by 831, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we take 5817 away from 5840, we end up with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 831

Moving on to step 6:
If we divide 235 by 831, we get 0 and a remainder of 235.
Record the quotient 0 as the next digit in the result. 
Result so far: 670.0
Subtract 0 from 235 to get 235.
Fetch the next digit (9) from the dividend, attach it to 235 and continue: 2359 / 831

Moving on to step 7:
If we divide 2359 by 831, we get 2 and a remainder of 697.
Use 2 as the next digit of our solution. 
Result so far: 6702.0
Deduct 1662 from 2359 and we're left with 697.
Fetch the next digit (1) from the dividend, attach it to 697 and continue: 6971 / 831

Moving on to step 8:
831 goes into 6971 8 times with a remainder of 323.
The next digit of our result is 8. 
Result so far: 67028.0
If we take 6648 away from 6971, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 9:
When dividing 3230 by 831, we get 3 with a remainder of 737.
The number 3 becomes the next digit in our result. 
Result so far: 67028.3
Subtracting 2493 from 3230 leaves us with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Advancing to step 10:
831 can be fit into 7370 8 times, resulting in a remainder of 722.
Put 8 as the next digit of the answer. 
Result so far: 67028.38
Subtracting 6648 from 7370 leaves us with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

On to step 11:
7220 divided by 831 is 8 with a remainder of 572.
The next digit of our result is 8. 
Result so far: 67028.388
If we subtract 6648 from 7220, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The final result is 67028.388 with a remainder of 0.0572.
