We look at the division of 509660 by 72 
We want to divide 509660 by 72.

On to step 1:
72 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 72

Let's proceed to step 2:
72 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 72

Advancing to step 3:
72 can be fit into 509 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 504 from 509 and we're left with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 72

Let's proceed to step 4:
The number 72 fits into 56 0 times, leaving a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we take 0 away from 56, we end up with 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 72

Going ahead to step 5:
566 divided by 72 is 7 with a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 707.0
Subtracting 504 from 566 leaves us with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 72

Advancing to step 6:
72 can be fit into 620 8 times, resulting in a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 7078.0
Deduct 576 from 620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
72 goes into 440 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 7078.6
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
72 goes into 80 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 7078.61
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.

Moving on to step 9:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 7078.611
Deduct 72 from 80 and we're left 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 7078.611 with a remaining 0.0008.
