We look at the division of 313681 by 68 
The aim is to understand the frequency of 68 in 313681.

Step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 68

Moving on to step 2:
68 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 68

Going ahead to step 3:
When dividing 313 by 68, we get 4 with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 41 after subtracting 272 from 313.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 68

Step 4:
If we divide 416 by 68, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtract 408 from 416 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 68

Moving on to step 5:
88 divided by 68 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 461.0
Subtract 68 from 88 to get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 68

On to step 6:
68 goes into 201 2 times with a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 4612.0
Subtracting 136 from 201 leaves us 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 next digit of our result is 9. 
Result so far: 4612.9
The remainder is 38 after subtracting 612 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
When dividing 380 by 68, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 4612.95
If we take 340 away from 380, 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.

Step 9:
400 divided by 68 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 4612.955
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 4612.955, with a leftover of 0.006.
