We look at the division of 86432681 by 831 
Our goal is to divide 86432681 by 831.

Let's proceed to step 1:
831 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 831

Advancing to step 2:
831 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 831

Moving on to step 3:
When dividing 864 by 831, we get 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 831 from 864 to get 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 831

On to step 4:
831 can be fit into 333 0 times, resulting in a remainder of 333.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 333 to get 333.
Bring next digit (2) of the dividend behind the 333 and repeat the process: 3332 / 831

Moving on to step 5:
If we divide 3332 by 831, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtract 3324 from 3332 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 831

Going ahead to step 6:
The number 831 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 831

Advancing to step 7:
The number 831 fits into 868 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 10401.0
If we take 831 away from 868, we end up with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 831

On to step 8:
831 goes into 371 0 times with a remainder of 371.
Use 0 as the next digit of our solution. 
Result so far: 104010.0
Deduct 0 from 371 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 9:
3710 divided by 831 is 4 with a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 104010.4
If we subtract 3324 from 3710, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 10:
When dividing 3860 by 831, we get 4 with a remainder of 536.
The next digit of our result is 4. 
Result so far: 104010.44
If we subtract 3324 from 3860, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Our division results in 104010.44 with a remaining 0.536.
