We look at the division of 17042 by 9 
The aim is to understand the frequency of 9 in 17042.

Advancing to step 1:
9 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 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.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 9 from 17 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 9

Let's proceed to step 3:
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: 18.0
Subtracting 72 from 80 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 9

Going ahead to step 4:
9 goes into 84 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we subtract 81 from 84, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 9

Going ahead to step 5:
The number 9 fits into 32 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1893.0
The remainder is 5 after subtracting 27 from 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 6:
9 goes into 50 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1893.5
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1893.55
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 1893.55 with a remainder of 0.005.
