We divide 175859 by 9
The aim is to understand the frequency of 9 in 175859.

Moving on to step 1:
When dividing 1 by 9, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 9

On to step 2:
The number 9 fits into 17 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 9 away from 17, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 9

Let's proceed to step 3:
If we divide 85 by 9, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 81 from 85, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 9

Step 4:
9 can be fit into 48 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 195.0
The remainder is 3 after subtracting 45 from 48.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Advancing to step 5:
9 goes into 35 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 1953.0
Deduct 27 from 35 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 9

Advancing to step 6:
If we divide 89 by 9, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 19539.0
The remainder is 8 after subtracting 81 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 9 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 19539.8
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
If we divide 80 by 9, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 19539.88
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 19539.88, with a leftover of 0.008.
