We're dividing 86682685 by 312 
We're looking to find how many times 312 goes into 86682685.

Advancing to step 1:
8 divided by 312 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 312

Going ahead to step 2:
312 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 312

Going ahead to step 3:
When dividing 866 by 312, we get 2 with a remainder of 242.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 624 from 866 to get 242.
Take the next digit (8) from the dividend and append it to 242, then repeat: 2428 / 312

Step 4:
If we divide 2428 by 312, we get 7 and a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 2184 from 2428 to get 244.
Bring next digit (2) of the dividend behind the 244 and repeat the process: 2442 / 312

Advancing to step 5:
The number 312 fits into 2442 7 times, leaving a remainder of 258.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
If we take 2184 away from 2442, we end up with 258.
Fetch the next digit (6) from the dividend, attach it to 258 and continue: 2586 / 312

Let's proceed to step 6:
The number 312 fits into 2586 8 times, leaving a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 2778.0
If we subtract 2496 from 2586, we get 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 312

On to step 7:
312 can be fit into 908 2 times, resulting in a remainder of 284.
Record the quotient 2 as the next digit in the result. 
Result so far: 27782.0
Deduct 624 from 908 and we're left with 284.
Grab the next digit (5) from the dividend, add it to 284, then carry on: 2845 / 312

Advancing to step 8:
When dividing 2845 by 312, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 277829.0
Subtracting 2808 from 2845 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
When dividing 370 by 312, we get 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 277829.1
If we subtract 312 from 370, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
The number 312 fits into 580 1 times, leaving a remainder of 268.
Use 1 as the next digit of our solution. 
Result so far: 277829.11
If we take 312 away from 580, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

In conclusion, the division gives 277829.11 with a balance of 0.268.
