We look at the division of 518581 by 72 
Let's see how many times 72 fits into 518581.

Advancing to step 1:
The number 72 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 72

Going ahead to step 2:
72 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 72

Let's proceed to step 3:
72 goes into 518 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 504 away from 518, we end up with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 72

Let's proceed to step 4:
If we divide 145 by 72, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 144 from 145, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 72

Step 5:
72 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 720.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 72

On to step 6:
The number 72 fits into 181 2 times, leaving a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 7202.0
If we subtract 144 from 181, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
72 goes into 370 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7202.5
Subtract 360 from 370 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.

Moving on to step 8:
72 can be fit into 100 1 times, resulting in a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 7202.51
The remainder is 28 after subtracting 72 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
280 divided by 72 is 3 with a remainder of 64.
The next digit of our result is 3. 
Result so far: 7202.513
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.

Step 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 7202.5138
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.

Step 11:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 7202.51388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 7202.51388 and a remainder of 6.4e-05.
