We're dividing 811200 by 72 
We're looking to find how many times 72 goes into 811200.

Advancing to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 72

Going ahead to step 2:
If we divide 81 by 72, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 72 from 81, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 72

Moving on to step 3:
If we divide 91 by 72, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 72 from 91 to get 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 72

On to step 4:
72 goes into 192 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtracting 144 from 192 leaves us with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 72

Step 5:
72 can be fit into 480 6 times, resulting in a remainder of 48.
The next digit of our result is 6. 
Result so far: 1126.0
Subtracting 432 from 480 leaves us with 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 72

Let's proceed to step 6:
72 can be fit into 480 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 11266.0
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 11266.6
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 11266.66
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 11266.66, and the remainder is 0.048.
