Let's divide 25208993 by 831
We want to divide 25208993 by 831.

Advancing to step 1:
831 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 831

Step 2:
The number 831 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 831

Step 3:
252 divided by 831 is 0 with a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 252, we get 252.
Grab the next digit (0) from the dividend, add it to 252, then carry on: 2520 / 831

Going ahead to step 4:
If we divide 2520 by 831, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2493 from 2520 and we're left with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 831

Going ahead to step 5:
The number 831 fits into 278 0 times, leaving a remainder of 278.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 278 and we're left with 278.
Take the next digit (9) from the dividend and append it to 278, then repeat: 2789 / 831

Going ahead to step 6:
831 goes into 2789 3 times with a remainder of 296.
Use 3 as the next digit of our solution. 
Result so far: 303.0
Subtracting 2493 from 2789 leaves us with 296.
Fetch the next digit (9) from the dividend, attach it to 296 and continue: 2969 / 831

Step 7:
831 goes into 2969 3 times with a remainder of 476.
The number 3 becomes the next digit in our result. 
Result so far: 3033.0
The remainder is 476 after subtracting 2493 from 2969.
Bring next digit (3) of the dividend behind the 476 and repeat the process: 4763 / 831

Going ahead to step 8:
831 can be fit into 4763 5 times, resulting in a remainder of 608.
The number 5 becomes the next digit in our result. 
Result so far: 30335.0
If we take 4155 away from 4763, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 9:
6080 divided by 831 is 7 with a remainder of 263.
Put 7 as the next digit of the answer. 
Result so far: 30335.7
If we take 5817 away from 6080, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 10:
When dividing 2630 by 831, we get 3 with a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 30335.73
Subtract 2493 from 2630 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 11:
If we divide 1370 by 831, we get 1 and a remainder of 539.
Write down 1 as next digit of the result. 
Result so far: 30335.731
Subtracting 831 from 1370 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Going ahead to step 12:
831 goes into 5390 6 times with a remainder of 404.
Record the quotient 6 as the next digit in the result. 
Result so far: 30335.7316
If we subtract 4986 from 5390, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 13:
If we divide 4040 by 831, we get 4 and a remainder of 716.
Put 4 as the next digit of the answer. 
Result so far: 30335.73164
Subtracting 3324 from 4040 leaves us with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Step 14:
The number 831 fits into 7160 8 times, leaving a remainder of 512.
Put 8 as the next digit of the answer. 
Result so far: 30335.731648
Deduct 6648 from 7160 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 15:
If we divide 5120 by 831, we get 6 and a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 30335.7316486
If we take 4986 away from 5120, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 16:
831 goes into 1340 1 times with a remainder of 509.
Write down 1 as next digit of the result. 
Result so far: 30335.73164861
Deduct 831 from 1340 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Our division results in 30335.73164861 with a remaining 5.09e-07.
