We look at the division of 959818 by 17 
The aim is to understand the frequency of 17 in 959818.

Let's proceed to step 1:
If we divide 9 by 17, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 17

Going ahead to step 2:
When dividing 95 by 17, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 10 after subtracting 85 from 95.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 17

Moving on to step 3:
The number 17 fits into 109 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
The remainder is 7 after subtracting 102 from 109.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 17

Let's proceed to step 4:
The number 17 fits into 78 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 564.0
The remainder is 10 after subtracting 68 from 78.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 17

Advancing to step 5:
The number 17 fits into 101 5 times, leaving a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 5645.0
If we subtract 85 from 101, we get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 17

Advancing to step 6:
The number 17 fits into 168 9 times, leaving a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 56459.0
Deduct 153 from 168 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
17 can be fit into 150 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 56459.8
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
17 goes into 140 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 56459.88
Subtracting 136 from 140 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 56459.88 with a remainder of 0.004.
