We look at the division of 478246 by 17 
The aim is to understand the frequency of 17 in 478246.

Advancing to step 1:
17 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 17

Let's proceed to step 2:
17 goes into 47 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 13 after subtracting 34 from 47.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 17

Moving on to step 3:
138 divided by 17 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 136 from 138 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 17

Moving on to step 4:
If we divide 22 by 17, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
The remainder is 5 after subtracting 17 from 22.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 17

Step 5:
The number 17 fits into 54 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 2813.0
Subtracting 51 from 54 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 17

Let's proceed to step 6:
If we divide 36 by 17, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 28132.0
Subtracting 34 from 36 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.

On to step 7:
The number 17 fits into 20 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 28132.1
Subtracting 17 from 20 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.

Let's proceed to step 8:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 28132.11
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 28132.11 with a remainder of 0.013.
