We're dividing 635289 by 17 
The aim is to understand the frequency of 17 in 635289.

Moving on to step 1:
If we divide 6 by 17, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 17

Step 2:
When dividing 63 by 17, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 51 away from 63, we end up with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 17

Step 3:
17 goes into 125 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 119 from 125 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 17

Going ahead to step 4:
The number 17 fits into 62 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
Subtract 51 from 62 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 17

On to step 5:
If we divide 118 by 17, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3736.0
Subtracting 102 from 118 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 17

Going ahead to step 6:
If we divide 169 by 17, we get 9 and a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 37369.0
Deduct 153 from 169 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 17 fits into 160 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 37369.9
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
70 divided by 17 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 37369.94
Subtract 68 from 70 to 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.

Step 9:
20 divided by 17 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 37369.941
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.

Let's proceed to step 10:
When dividing 30 by 17, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 37369.9411
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.

The final outcome is 37369.9411, with a leftover of 0.00013.
