We look at the division of 935257 by 17 
The aim is to understand the frequency of 17 in 935257.

On to step 1:
17 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 17

Advancing to step 2:
The number 17 fits into 93 5 times, leaving a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 85 from 93 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 17

Moving on to step 3:
17 can be fit into 85 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 85 from 85 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 17

Let's proceed to step 4:
The number 17 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 550.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 17

Advancing to step 5:
17 goes into 25 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 5501.0
If we take 17 away from 25, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 17

Step 6:
When dividing 87 by 17, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 55015.0
If we take 85 away from 87, we end up 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 7:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 55015.1
If we subtract 17 from 20, 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.

Going ahead to step 8:
If we divide 30 by 17, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 55015.11
Deduct 17 from 30 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 55015.11 with a remaining 0.013.
