Let's divide 86831317 by 680
Our goal is to divide 86831317 by 680.

On to step 1:
8 divided by 680 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 680

Advancing to step 2:
680 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
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 / 680

Step 3:
If we divide 868 by 680, we get 1 and a remainder of 188.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 680 from 868 leaves us with 188.
Bring next digit (3) of the dividend behind the 188 and repeat the process: 1883 / 680

On to step 4:
When dividing 1883 by 680, we get 2 with a remainder of 523.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1360 from 1883 and we're left with 523.
Append the next digit (1) from the dividend to 523 and continue with: 5231 / 680

Step 5:
If we divide 5231 by 680, we get 7 and a remainder of 471.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 4760 from 5231, we get 471.
Take the next digit (3) from the dividend and append it to 471, then repeat: 4713 / 680

Going ahead to step 6:
680 goes into 4713 6 times with a remainder of 633.
Write down 6 as next digit of the result. 
Result so far: 1276.0
The remainder is 633 after subtracting 4080 from 4713.
Take the next digit (1) from the dividend and append it to 633, then repeat: 6331 / 680

On to step 7:
If we divide 6331 by 680, we get 9 and a remainder of 211.
Record the quotient 9 as the next digit in the result. 
Result so far: 12769.0
If we subtract 6120 from 6331, we get 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 680

Step 8:
The number 680 fits into 2117 3 times, leaving a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 127693.0
The remainder is 77 after subtracting 2040 from 2117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
680 can be fit into 770 1 times, resulting in a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 127693.1
If we subtract 680 from 770, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
When dividing 900 by 680, we get 1 with a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 127693.11
Subtracting 680 from 900 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 127693.11, with a leftover of 0.22.
