We look at the division of 85986230 by 831 
Our goal is to divide 85986230 by 831.

Going ahead to step 1:
831 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 831

On to step 2:
When dividing 85 by 831, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 831

Going ahead to step 3:
831 can be fit into 859 1 times, resulting in a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 831 from 859 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 831

Going ahead to step 4:
288 divided by 831 is 0 with a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 288, we end up with 288.
Fetch the next digit (6) from the dividend, attach it to 288 and continue: 2886 / 831

Moving on to step 5:
When dividing 2886 by 831, we get 3 with a remainder of 393.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtracting 2493 from 2886 leaves us with 393.
Append the next digit (2) from the dividend to 393 and continue with: 3932 / 831

Moving on to step 6:
831 can be fit into 3932 4 times, resulting in a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 1034.0
The remainder is 608 after subtracting 3324 from 3932.
Take the next digit (3) from the dividend and append it to 608, then repeat: 6083 / 831

Step 7:
831 can be fit into 6083 7 times, resulting in a remainder of 266.
Use 7 as the next digit of our solution. 
Result so far: 10347.0
If we subtract 5817 from 6083, we get 266.
Fetch the next digit (0) from the dividend, attach it to 266 and continue: 2660 / 831

Let's proceed to step 8:
2660 divided by 831 is 3 with a remainder of 167.
Write down 3 as next digit of the result. 
Result so far: 103473.0
Subtracting 2493 from 2660 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 9:
When dividing 1670 by 831, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 103473.2
Subtract 1662 from 1670 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 831, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 103473.2
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
The number 831 fits into 800 0 times, leaving a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 103473.2
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 103473.2, and the remainder is 0.08.
