We look at the division of 16175 by 9 
The aim is to understand the frequency of 9 in 16175.

Step 1:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 9

Step 2:
16 divided by 9 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 9 away from 16, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 9

Going ahead to step 3:
If we divide 71 by 9, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 63 from 71 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 9

Let's proceed to step 4:
The number 9 fits into 87 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 179.0
If we take 81 away from 87, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 9

Let's proceed to step 5:
When dividing 65 by 9, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 1797.0
Deduct 63 from 65 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 6:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1797.2
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
9 can be fit into 20 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 1797.22
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 1797.22 and a remainder of 0.002.
