We look at the division of 178752 by 72 
The aim is to understand the frequency of 72 in 178752.

Let's proceed to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 72

Let's proceed to step 2:
72 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 72

Going ahead to step 3:
72 goes into 178 2 times with a remainder of 34.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 144 from 178, we get 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 72

Moving on to step 4:
The number 72 fits into 347 4 times, leaving a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 288 from 347 and we're left with 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 72

Moving on to step 5:
If we divide 595 by 72, we get 8 and a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 248.0
Subtracting 576 from 595 leaves us with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 72

Let's proceed to step 6:
72 goes into 192 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 2482.0
Subtracting 144 from 192 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.

On to step 7:
480 divided by 72 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 2482.6
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.

Let's proceed to step 8:
When dividing 480 by 72, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 2482.66
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.

After the division, we end up with 2482.66 and a remainder of 0.048.
