We look at the division of 39417 by 68 
The aim is to understand the frequency of 68 in 39417.

Moving on to step 1:
When dividing 3 by 68, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 68

Going ahead to step 2:
68 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 68

Step 3:
68 goes into 394 5 times with a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 340 from 394 leaves us with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 68

Step 4:
541 divided by 68 is 7 with a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 476 from 541 leaves us with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 68

Step 5:
The number 68 fits into 657 9 times, leaving a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 579.0
Subtracting 612 from 657 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 6:
When dividing 450 by 68, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 579.6
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
When dividing 420 by 68, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 579.66
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 579.66 with a remaining 0.012.
