Let's divide 338539 by 17
The aim is to understand the frequency of 17 in 338539.

Advancing to step 1:
17 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 17

Moving on to step 2:
The number 17 fits into 33 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 17 from 33, we get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 17

On to step 3:
When dividing 168 by 17, we get 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 153 from 168, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 17

Step 4:
155 divided by 17 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 199.0
Deduct 153 from 155 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 17

Advancing to step 5:
If we divide 23 by 17, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1991.0
Deduct 17 from 23 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 17

Moving on to step 6:
The number 17 fits into 69 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 19914.0
If we subtract 68 from 69, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 17, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 19914.0
Deduct 0 from 10 and we're left 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.

Advancing to step 8:
The number 17 fits into 100 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 19914.05
Subtracting 85 from 100 leaves us 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.

Step 9:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 19914.058
Deduct 136 from 150 and we're left with 14.
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 10:
The number 17 fits into 140 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 19914.0588
If we subtract 136 from 140, we get 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 quotient of the division is 19914.0588, and the remainder is 4e-05.
