We're dividing 539469 by 17 
The aim is to understand the frequency of 17 in 539469.

Step 1:
When dividing 5 by 17, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 17

Going ahead to step 2:
17 goes into 53 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 51 away from 53, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 17

Step 3:
17 can be fit into 29 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 12 after subtracting 17 from 29.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 17

On to step 4:
17 goes into 124 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 317.0
If we subtract 119 from 124, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 17

Advancing to step 5:
If we divide 56 by 17, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3173.0
Deduct 51 from 56 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 17

Let's proceed to step 6:
If we divide 59 by 17, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 31733.0
The remainder is 8 after subtracting 51 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
17 can be fit into 80 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 31733.4
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 17 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 31733.47
Deduct 119 from 120 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 17 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 31733.47
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 17 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 31733.4705
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
When dividing 150 by 17, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 31733.47058
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 12:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 31733.470588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 31733.470588 with a remaining 4e-07.
