86772879 divided by 256 
We're looking to find how many times 256 goes into 86772879.

On to step 1:
256 goes into 8 0 times with 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.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 256

Moving on to step 2:
The number 256 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 256

Advancing to step 3:
256 can be fit into 867 3 times, resulting in a remainder of 99.
The next digit of our result is 3. 
Result so far: 3.0
If we take 768 away from 867, we end up with 99.
Grab the next digit (7) from the dividend, add it to 99, then carry on: 997 / 256

Step 4:
256 goes into 997 3 times with a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 768 from 997 leaves us with 229.
Append the next digit (2) from the dividend to 229 and continue with: 2292 / 256

Advancing to step 5:
When dividing 2292 by 256, we get 8 with a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 338.0
If we subtract 2048 from 2292, we get 244.
Fetch the next digit (8) from the dividend, attach it to 244 and continue: 2448 / 256

Advancing to step 6:
2448 divided by 256 is 9 with a remainder of 144.
The next digit of our result is 9. 
Result so far: 3389.0
Subtracting 2304 from 2448 leaves us with 144.
Append the next digit (7) from the dividend to 144 and continue with: 1447 / 256

Let's proceed to step 7:
1447 divided by 256 is 5 with a remainder of 167.
The number 5 becomes the next digit in our result. 
Result so far: 33895.0
Deduct 1280 from 1447 and we're left with 167.
Bring next digit (9) of the dividend behind the 167 and repeat the process: 1679 / 256

Step 8:
256 can be fit into 1679 6 times, resulting in a remainder of 143.
The next digit of our result is 6. 
Result so far: 338956.0
The remainder is 143 after subtracting 1536 from 1679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 9:
When dividing 1430 by 256, we get 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 338956.5
If we take 1280 away from 1430, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
256 can be fit into 1500 5 times, resulting in a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 338956.55
If we subtract 1280 from 1500, we get 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 result is 338956.55 with a remainder of 0.22.
