We look at the division of 801129 by 9 
The aim is to understand the frequency of 9 in 801129.

Step 1:
9 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 9

Going ahead to step 2:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 8 after subtracting 72 from 80.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 9

Let's proceed to step 3:
The number 9 fits into 81 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we take 81 away from 81, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 9

On to step 4:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 890.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 9

Moving on to step 5:
12 divided by 9 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 8901.0
Subtracting 9 from 12 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 9

Advancing to step 6:
If we divide 39 by 9, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 89014.0
If we subtract 36 from 39, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
9 goes into 30 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 89014.3
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.

Step 8:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 89014.33
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.

In conclusion, the division gives 89014.33 with a balance of 0.003.
