520176 ÷ 72 
We want to figure out the number of times 520176 can be divided by 72.

Let's proceed to step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 72

Let's proceed to step 2:
52 divided by 72 is 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 72

Step 3:
The number 72 fits into 520 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 16 after subtracting 504 from 520.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 72

Moving on to step 4:
The number 72 fits into 161 2 times, leaving a remainder of 17.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 144 from 161 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 72

On to step 5:
When dividing 177 by 72, we get 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 722.0
Subtracting 144 from 177 leaves us with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 72

On to step 6:
The number 72 fits into 336 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 7224.0
Subtracting 288 from 336 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 72 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7224.6
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 7224.66
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 7224.66 and a remainder of 0.048.
