We're dividing 726323 by 68 
The aim is to understand the frequency of 68 in 726323.

On to step 1:
When dividing 7 by 68, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 68

Step 2:
The number 68 fits into 72 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 68 from 72 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 68

Let's proceed to step 3:
When dividing 46 by 68, we get 0 with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 46 after subtracting 0 from 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 68

Let's proceed to step 4:
When dividing 463 by 68, we get 6 with a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 106.0
The remainder is 55 after subtracting 408 from 463.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 68

On to step 5:
The number 68 fits into 552 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1068.0
Subtract 544 from 552 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 68

Moving on to step 6:
68 goes into 83 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 10681.0
Subtracting 68 from 83 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
68 goes into 150 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 10681.2
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
68 goes into 140 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10681.22
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 10681.22 and a remainder of 0.004.
