Let's divide 72085611 by 863
We want to divide 72085611 by 863.

On to step 1:
863 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 863

Step 2:
863 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 863

Let's proceed to step 3:
863 can be fit into 720 0 times, resulting in a remainder of 720.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 720 after subtracting 0 from 720.
Take the next digit (8) from the dividend and append it to 720, then repeat: 7208 / 863

On to step 4:
If we divide 7208 by 863, we get 8 and a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6904 away from 7208, we end up with 304.
Grab the next digit (5) from the dividend, add it to 304, then carry on: 3045 / 863

On to step 5:
863 can be fit into 3045 3 times, resulting in a remainder of 456.
Write down 3 as next digit of the result. 
Result so far: 83.0
The remainder is 456 after subtracting 2589 from 3045.
Append the next digit (6) from the dividend to 456 and continue with: 4566 / 863

Going ahead to step 6:
If we divide 4566 by 863, we get 5 and a remainder of 251.
The number 5 becomes the next digit in our result. 
Result so far: 835.0
If we take 4315 away from 4566, we end up with 251.
Fetch the next digit (1) from the dividend, attach it to 251 and continue: 2511 / 863

Moving on to step 7:
If we divide 2511 by 863, we get 2 and a remainder of 785.
Use 2 as the next digit of our solution. 
Result so far: 8352.0
Subtract 1726 from 2511 to get 785.
Append the next digit (1) from the dividend to 785 and continue with: 7851 / 863

On to step 8:
If we divide 7851 by 863, we get 9 and a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 83529.0
Subtracting 7767 from 7851 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 9:
840 divided by 863 is 0 with a remainder of 840.
The next digit of our result is 0. 
Result so far: 83529.0
Deduct 0 from 840 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 10:
863 can be fit into 8400 9 times, resulting in a remainder of 633.
Write down 9 as next digit of the result. 
Result so far: 83529.09
If we subtract 7767 from 8400, we get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

On to step 11:
The number 863 fits into 6330 7 times, leaving a remainder of 289.
Put 7 as the next digit of the answer. 
Result so far: 83529.097
Subtract 6041 from 6330 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 12:
863 can be fit into 2890 3 times, resulting in a remainder of 301.
Use 3 as the next digit of our solution. 
Result so far: 83529.0973
Subtract 2589 from 2890 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 13:
863 goes into 3010 3 times with a remainder of 421.
The next digit of our result is 3. 
Result so far: 83529.09733
Subtract 2589 from 3010 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

The quotient of the division is 83529.09733, and the remainder is 0.000421.
