We look at the division of 865252 by 72 
The aim is to understand the frequency of 72 in 865252.

Going ahead to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 72

Moving on to step 2:
When dividing 86 by 72, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 72 from 86 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 72

Moving on to step 3:
If we divide 145 by 72, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 144 from 145 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 72

Going ahead to step 4:
12 divided by 72 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 120.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 72

On to step 5:
125 divided by 72 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1201.0
Deduct 72 from 125 and we're left with 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 72

Let's proceed to step 6:
72 can be fit into 532 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 12017.0
Subtracting 504 from 532 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
280 divided by 72 is 3 with a remainder of 64.
The next digit of our result is 3. 
Result so far: 12017.3
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 12017.38
Deduct 576 from 640 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:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 12017.388
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.

In conclusion, the division gives 12017.388 with a balance of 0.0064.
