We look at the division of 83520 by 72 
We're looking to find how many times 72 goes into 83520.

Moving on to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 72

Let's proceed to step 2:
72 can be fit into 83 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 72 from 83 and we're left with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 72

Let's proceed to step 3:
When dividing 115 by 72, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 43 after subtracting 72 from 115.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 72

Let's proceed to step 4:
When dividing 432 by 72, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we take 432 away from 432, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 72

Moving on to step 5:
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: 1160.0
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.

Step 6:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1160.0
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.

Going ahead to step 7:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1160.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1160.0, with a leftover of 0.0.
