We're dividing 172272 by 9 
The aim is to understand the frequency of 9 in 172272.

Advancing to step 1:
When dividing 1 by 9, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 9

Advancing to step 2:
When dividing 17 by 9, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 9 from 17 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 9

Going ahead to step 3:
If we divide 82 by 9, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 81 from 82 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 9

Let's proceed to step 4:
If we divide 12 by 9, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
Subtracting 9 from 12 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 9

Going ahead to step 5:
The number 9 fits into 37 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 1914.0
Subtract 36 from 37 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 9

On to step 6:
12 divided by 9 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 19141.0
Deduct 9 from 12 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 9 fits into 30 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 19141.3
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
If we divide 30 by 9, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 19141.33
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 19141.33 with a balance of 0.003.
