We look at the division of 723994 by 93 
The aim is to understand the frequency of 93 in 723994.

Let's proceed to step 1:
When dividing 7 by 93, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 93

Advancing to step 2:
When dividing 72 by 93, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 93

Step 3:
93 goes into 723 7 times with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 651 from 723, we get 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 93

Moving on to step 4:
93 can be fit into 729 7 times, resulting in a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 651 from 729 to get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 93

Advancing to step 5:
789 divided by 93 is 8 with a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 778.0
Subtracting 744 from 789 leaves us with 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 93

Advancing to step 6:
454 divided by 93 is 4 with a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 7784.0
If we take 372 away from 454, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 7:
93 goes into 820 8 times with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 7784.8
The remainder is 76 after subtracting 744 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
The number 93 fits into 760 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 7784.88
Deduct 744 from 760 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 7784.88 with a remaining 0.016.
