We're dividing 76068863 by 864 
We want to divide 76068863 by 864.

Going ahead to step 1:
7 divided by 864 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 864

Step 2:
If we divide 76 by 864, we get 0 and a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 864

On to step 3:
If we divide 760 by 864, we get 0 and a remainder of 760.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 760 leaves us with 760.
Append the next digit (6) from the dividend to 760 and continue with: 7606 / 864

Moving on to step 4:
When dividing 7606 by 864, we get 8 with a remainder of 694.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6912 from 7606 leaves us with 694.
Bring next digit (8) of the dividend behind the 694 and repeat the process: 6948 / 864

Step 5:
The number 864 fits into 6948 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 88.0
If we take 6912 away from 6948, we end up with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 864

Let's proceed to step 6:
If we divide 368 by 864, we get 0 and a remainder of 368.
Record the quotient 0 as the next digit in the result. 
Result so far: 880.0
Subtract 0 from 368 to get 368.
Bring next digit (6) of the dividend behind the 368 and repeat the process: 3686 / 864

On to step 7:
864 goes into 3686 4 times with a remainder of 230.
The next digit of our result is 4. 
Result so far: 8804.0
The remainder is 230 after subtracting 3456 from 3686.
Append the next digit (3) from the dividend to 230 and continue with: 2303 / 864

Advancing to step 8:
2303 divided by 864 is 2 with a remainder of 575.
Use 2 as the next digit of our solution. 
Result so far: 88042.0
Subtract 1728 from 2303 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 9:
5750 divided by 864 is 6 with a remainder of 566.
Put 6 as the next digit of the answer. 
Result so far: 88042.6
Subtract 5184 from 5750 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Step 10:
When dividing 5660 by 864, we get 6 with a remainder of 476.
Record the quotient 6 as the next digit in the result. 
Result so far: 88042.66
The remainder is 476 after subtracting 5184 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Our division results in 88042.66 with a remaining 0.476.
