We're dividing 87056764 by 863 
We want to divide 87056764 by 863.

Going ahead to step 1:
If we divide 8 by 863, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 863

Advancing to step 2:
If we divide 87 by 863, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 863

Advancing to step 3:
863 goes into 870 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 863 from 870 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 863

Step 4:
The number 863 fits into 75 0 times, leaving a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 75 leaves us with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 863

Going ahead to step 5:
863 can be fit into 756 0 times, resulting in a remainder of 756.
The next digit of our result is 0. 
Result so far: 100.0
The remainder is 756 after subtracting 0 from 756.
Take the next digit (7) from the dividend and append it to 756, then repeat: 7567 / 863

Step 6:
The number 863 fits into 7567 8 times, leaving a remainder of 663.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
Subtracting 6904 from 7567 leaves us with 663.
Fetch the next digit (6) from the dividend, attach it to 663 and continue: 6636 / 863

Step 7:
863 goes into 6636 7 times with a remainder of 595.
Record the quotient 7 as the next digit in the result. 
Result so far: 10087.0
Subtract 6041 from 6636 to get 595.
Append the next digit (4) from the dividend to 595 and continue with: 5954 / 863

Going ahead to step 8:
863 goes into 5954 6 times with a remainder of 776.
Use 6 as the next digit of our solution. 
Result so far: 100876.0
Deduct 5178 from 5954 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Moving on to step 9:
The number 863 fits into 7760 8 times, leaving a remainder of 856.
Use 8 as the next digit of our solution. 
Result so far: 100876.8
If we subtract 6904 from 7760, we get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Going ahead to step 10:
If we divide 8560 by 863, we get 9 and a remainder of 793.
Put 9 as the next digit of the answer. 
Result so far: 100876.89
Deduct 7767 from 8560 and we're left with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Moving on to step 11:
863 goes into 7930 9 times with a remainder of 163.
Put 9 as the next digit of the answer. 
Result so far: 100876.899
If we take 7767 away from 7930, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Our division results in 100876.899 with a remaining 0.0163.
