We look at the division of 527709 by 9 
The aim is to understand the frequency of 9 in 527709.

Advancing to step 1:
When dividing 5 by 9, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 9

Moving on to step 2:
When dividing 52 by 9, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 45 away from 52, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 9

Advancing to step 3:
The number 9 fits into 77 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtract 72 from 77 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 9

Moving on to step 4:
9 can be fit into 57 6 times, resulting in a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 586.0
Subtracting 54 from 57 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Let's proceed to step 5:
When dividing 30 by 9, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 5863.0
If we take 27 away from 30, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 9

Advancing to step 6:
9 can be fit into 39 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 58634.0
Subtract 36 from 39 to 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.

Going ahead to step 7:
30 divided by 9 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 58634.3
If we subtract 27 from 30, 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.

Step 8:
9 goes into 30 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 58634.33
If we take 27 away from 30, we end up 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 58634.33 with a balance of 0.003.
