We're dividing 572880 by 72 
The aim is to understand the frequency of 72 in 572880.

Let's proceed to step 1:
5 divided by 72 is 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.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 72

Going ahead to step 2:
72 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 72

Advancing to step 3:
If we divide 572 by 72, we get 7 and a remainder of 68.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 504 from 572 leaves us with 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 72

Advancing to step 4:
688 divided by 72 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 648 from 688, we get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 72

Moving on to step 5:
The number 72 fits into 408 5 times, leaving a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 795.0
Deduct 360 from 408 and we're left with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 72

On to step 6:
When dividing 480 by 72, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 7956.0
If we take 432 away from 480, we end up 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.

On to step 7:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7956.6
Subtracting 432 from 480 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 8:
If we divide 480 by 72, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7956.66
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 7956.66 and a remainder of 0.048.
