We look at the division of 748387 by 68 
The aim is to understand the frequency of 68 in 748387.

Advancing to step 1:
When dividing 7 by 68, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 68

Let's proceed to step 2:
68 can be fit into 74 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 68 from 74, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 68

Advancing to step 3:
If we divide 68 by 68, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 68 from 68 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 68

Step 4:
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: 110.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 68

On to step 5:
68 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 1100.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 68

On to step 6:
If we divide 387 by 68, we get 5 and a remainder of 47.
The number 5 becomes the next digit in our result. 
Result so far: 11005.0
Deduct 340 from 387 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
470 divided by 68 is 6 with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 11005.6
The remainder is 62 after subtracting 408 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
The number 68 fits into 620 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 11005.69
Subtracting 612 from 620 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
68 can be fit into 80 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 11005.691
Subtracting 68 from 80 leaves us 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.

Moving on to step 10:
If we divide 120 by 68, we get 1 and a remainder of 52.
The next digit of our result is 1. 
Result so far: 11005.6911
Subtracting 68 from 120 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 11005.6911, with a leftover of 0.00052.
