We look at the division of 61839 by 17 
The aim is to understand the frequency of 17 in 61839.

Going ahead to step 1:
If we divide 6 by 17, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 17

Let's proceed to step 2:
When dividing 61 by 17, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 51 from 61 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 17

Step 3:
17 can be fit into 108 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 102 from 108 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 17

Going ahead to step 4:
17 can be fit into 63 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 363.0
Subtract 51 from 63 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 17

Going ahead to step 5:
17 can be fit into 129 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 3637.0
If we take 119 away from 129, we end up 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.

On to step 6:
17 goes into 100 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3637.5
If we take 85 away from 100, we end up 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 7:
When dividing 150 by 17, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 3637.58
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
17 goes into 140 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3637.588
If we take 136 away from 140, we end up 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 outcome is 3637.588, with a leftover of 0.0004.
