We look at the division of 939512 by 17 
The aim is to understand the frequency of 17 in 939512.

Moving on to step 1:
The number 17 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 17

Moving on to step 2:
When dividing 93 by 17, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
If we take 85 away from 93, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 17

Let's proceed to step 3:
When dividing 89 by 17, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtracting 85 from 89 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 17

Advancing to step 4:
If we divide 45 by 17, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 552.0
Subtract 34 from 45 to get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 17

Going ahead to step 5:
111 divided by 17 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 5526.0
If we subtract 102 from 111, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 17

Moving on to step 6:
92 divided by 17 is 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 55265.0
Subtracting 85 from 92 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 55265.4
If we subtract 68 from 70, we get 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 8:
If we divide 20 by 17, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 55265.41
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
30 divided by 17 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 55265.411
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.

After the division, we end up with 55265.411 and a remainder of 0.0013.
