We look at the division of 516250 by 72 
We want to figure out the number of times 516250 can be divided by 72.

Step 1:
When dividing 5 by 72, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 72

Advancing to step 2:
72 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 72

Let's proceed to step 3:
516 divided by 72 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 12 after subtracting 504 from 516.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 72

Moving on to step 4:
72 goes into 122 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 50 after subtracting 72 from 122.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 72

On to step 5:
505 divided by 72 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 717.0
Subtracting 504 from 505 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 72

On to step 6:
The number 72 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7170.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 72, we get 1 and a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 7170.1
Subtract 72 from 100 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
If we divide 280 by 72, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 7170.13
Deduct 216 from 280 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
If we divide 640 by 72, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 7170.138
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 7170.1388
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 7170.1388, with a leftover of 0.00064.
