We look at the division of 388864 by 68 
The aim is to understand the frequency of 68 in 388864.

Moving on to step 1:
3 divided by 68 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 68

Let's proceed to step 2:
When dividing 38 by 68, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 68

Moving on to step 3:
The number 68 fits into 388 5 times, leaving a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 340 from 388 and we're left with 48.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 68

Advancing to step 4:
If we divide 488 by 68, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we subtract 476 from 488, we get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 68

Step 5:
68 can be fit into 126 1 times, resulting in a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 571.0
Subtracting 68 from 126 leaves us with 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 68

Moving on to step 6:
68 can be fit into 584 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 5718.0
If we take 544 away from 584, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
68 goes into 400 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 5718.5
Subtracting 340 from 400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 68 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 5718.58
Subtract 544 from 600 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
68 can be fit into 560 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 5718.588
Deduct 544 from 560 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 5718.588 with a remaining 0.0016.
