We look at the division of 326329 by 68 
The aim is to understand the frequency of 68 in 326329.

On to step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 68

Advancing to step 2:
68 goes into 32 0 times with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 68

Step 3:
326 divided by 68 is 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 272 away from 326, we end up with 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 68

Let's proceed to step 4:
When dividing 543 by 68, we get 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 476 from 543 leaves us with 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 68

Advancing to step 5:
68 goes into 672 9 times with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 479.0
Subtracting 612 from 672 leaves us with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 68

Let's proceed to step 6:
68 goes into 609 8 times with a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 4798.0
Deduct 544 from 609 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
650 divided by 68 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4798.9
Deduct 612 from 650 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
If we divide 380 by 68, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 4798.95
Subtracting 340 from 380 leaves us 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.

On to step 9:
The number 68 fits into 400 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 4798.955
If we take 340 away from 400, we end up 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.

After the division, we end up with 4798.955 and a remainder of 0.006.
