975228 ÷ 72 
The aim is to understand the frequency of 72 in 975228.

Step 1:
72 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 72

Going ahead to step 2:
97 divided by 72 is 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 25 after subtracting 72 from 97.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 72

Advancing to step 3:
The number 72 fits into 255 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 216 from 255 to get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 72

Moving on to step 4:
If we divide 392 by 72, we get 5 and a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we subtract 360 from 392, we get 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 72

Moving on to step 5:
The number 72 fits into 322 4 times, leaving a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1354.0
Subtract 288 from 322 to get 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 72

Moving on to step 6:
If we divide 348 by 72, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 13544.0
Deduct 288 from 348 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
72 can be fit into 600 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 13544.8
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
72 goes into 240 3 times with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 13544.83
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
If we divide 240 by 72, we get 3 and a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 13544.833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 13544.833 with a balance of 0.0024.
