803520 ÷ 72 
We want to divide 803520 by 72.

Step 1:
72 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 72

Going ahead to step 2:
72 can be fit into 80 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 80 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 72

Let's proceed to step 3:
83 divided by 72 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 72 from 83 leaves us with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 72

Advancing to step 4:
The number 72 fits into 115 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 111.0
Subtracting 72 from 115 leaves us with 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 72

Going ahead to step 5:
432 divided by 72 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1116.0
If we subtract 432 from 432, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 72

Moving on to step 6:
72 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11160.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 72, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11160.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 72, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11160.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 11160.0 and a remainder of 0.0.
