We look at the division of 517716 by 72 
We want to figure out the number of times 517716 can be divided by 72.

On to step 1:
The number 72 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 72

Advancing to step 2:
51 divided by 72 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 72

Advancing to step 3:
517 divided by 72 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 504 from 517, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 72

Moving on to step 4:
137 divided by 72 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtracting 72 from 137 leaves us with 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 72

On to step 5:
651 divided by 72 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 719.0
Deduct 648 from 651 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 72

Step 6:
36 divided by 72 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 7190.0
Subtracting 0 from 36 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
When dividing 360 by 72, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7190.5
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
72 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7190.5
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.

Advancing to step 9:
0 divided by 72 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7190.5
Deduct 0 from 0 and we're left 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.

Our division results in 7190.5 with a remaining 0.0.
