69639 ÷ 17 
The aim is to understand the frequency of 17 in 69639.

Moving on to step 1:
When dividing 6 by 17, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 17

Going ahead to step 2:
17 can be fit into 69 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 68 from 69 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 17

Moving on to step 3:
16 divided by 17 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 17

Going ahead to step 4:
If we divide 163 by 17, we get 9 and a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
Subtract 153 from 163 to get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 17

Let's proceed to step 5:
When dividing 109 by 17, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 4096.0
The remainder is 7 after subtracting 102 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 6:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4096.4
Subtracting 68 from 70 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 17, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4096.41
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 8:
30 divided by 17 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 4096.411
If we take 17 away from 30, we end up 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.

Our division results in 4096.411 with a remaining 0.0013.
