We're dividing 831949 by 86 
We're looking to find how many times 86 goes into 831949.

Going ahead to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 86

Advancing to step 2:
If we divide 83 by 86, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 86

On to step 3:
The number 86 fits into 831 9 times, leaving a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 774 from 831 to get 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 86

Let's proceed to step 4:
86 can be fit into 579 6 times, resulting in a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 96.0
If we subtract 516 from 579, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 86

Let's proceed to step 5:
86 can be fit into 634 7 times, resulting in a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 967.0
Subtracting 602 from 634 leaves us with 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 86

Advancing to step 6:
329 divided by 86 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 9673.0
Subtracting 258 from 329 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
If we divide 710 by 86, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 9673.8
The remainder is 22 after subtracting 688 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
If we divide 220 by 86, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 9673.82
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
86 goes into 480 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 9673.825
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 9673.8255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 9673.8255, with a leftover of 0.0007.
