863864 divided by 72 
We want to divide 863864 by 72.

Let's proceed to step 1:
When dividing 8 by 72, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
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 / 72

Step 2:
The number 72 fits into 86 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 72 from 86 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 72

Advancing to step 3:
If we divide 143 by 72, we get 1 and a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 71 after subtracting 72 from 143.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 72

Let's proceed to step 4:
If we divide 718 by 72, we get 9 and a remainder of 70.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 648 from 718 leaves us with 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 72

Going ahead to step 5:
72 goes into 706 9 times with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 1199.0
Subtract 648 from 706 to get 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 72

On to step 6:
72 can be fit into 584 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 11998.0
The remainder is 8 after subtracting 576 from 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
72 goes into 80 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 11998.1
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 72 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 11998.11
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 11998.11, with a leftover of 0.008.
