The number 72 fits into 440 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10408.6
Subtracting 432 from 440 leaves us 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.

Advancing to step 8:
80 divided by 72 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 10408.61
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 72, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 10408.611
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.

Our division results in 10408.611 with a remaining 0.0008.
