We look at the division of 127120 by 9 
The aim is to understand the frequency of 9 in 127120.

Going ahead to step 1:
When dividing 1 by 9, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 9

Advancing to step 2:
9 goes into 12 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 9 from 12, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 9

On to step 3:
The number 9 fits into 37 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 36 from 37 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

Going ahead to step 4:
If we divide 11 by 9, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtract 9 from 11 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 9

Let's proceed to step 5:
9 goes into 22 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 1412.0
If we subtract 18 from 22, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 9

Going ahead to step 6:
If we divide 40 by 9, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 14124.0
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 14124.4
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 14124.44
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 14124.44 with a remainder of 0.004.
