Let's divide 23257142 by 831
We want to divide 23257142 by 831.

Going ahead to step 1:
831 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 831

Going ahead to step 2:
The number 831 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 831

On to step 3:
831 goes into 232 0 times with a remainder of 232.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 232 after subtracting 0 from 232.
Take the next digit (5) from the dividend and append it to 232, then repeat: 2325 / 831

Let's proceed to step 4:
When dividing 2325 by 831, we get 2 with a remainder of 663.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1662 from 2325, we get 663.
Take the next digit (7) from the dividend and append it to 663, then repeat: 6637 / 831

Advancing to step 5:
6637 divided by 831 is 7 with a remainder of 820.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 5817 from 6637, we get 820.
Include the next digit (1) from the dividend after 820, then repeat: 8201 / 831

Let's proceed to step 6:
When dividing 8201 by 831, we get 9 with a remainder of 722.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
If we subtract 7479 from 8201, we get 722.
Fetch the next digit (4) from the dividend, attach it to 722 and continue: 7224 / 831

Step 7:
831 goes into 7224 8 times with a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 2798.0
Subtract 6648 from 7224 to get 576.
Fetch the next digit (2) from the dividend, attach it to 576 and continue: 5762 / 831

Going ahead to step 8:
When dividing 5762 by 831, we get 6 with a remainder of 776.
The next digit of our result is 6. 
Result so far: 27986.0
Subtract 4986 from 5762 to get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Let's proceed to step 9:
If we divide 7760 by 831, we get 9 and a remainder of 281.
The next digit of our result is 9. 
Result so far: 27986.9
If we take 7479 away from 7760, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Step 10:
When dividing 2810 by 831, we get 3 with a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 27986.93
Subtracting 2493 from 2810 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 11:
831 can be fit into 3170 3 times, resulting in a remainder of 677.
The number 3 becomes the next digit in our result. 
Result so far: 27986.933
Deduct 2493 from 3170 and we're left with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Our division results in 27986.933 with a remaining 0.0677.
