We're dividing 792399 by 30 
The aim is to understand the frequency of 30 in 792399.

Moving on to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 30

Let's proceed to step 2:
The number 30 fits into 79 2 times, leaving a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 60 from 79, we get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 30

On to step 3:
192 divided by 30 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 180 from 192 and we're left with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 30

Step 4:
30 goes into 123 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 264.0
If we take 120 away from 123, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 30

Advancing to step 5:
When dividing 39 by 30, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2641.0
Subtract 30 from 39 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 30

Moving on to step 6:
The number 30 fits into 99 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 26413.0
If we subtract 90 from 99, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
30 goes into 90 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 26413.3
Subtracting 90 from 90 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26413.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26413.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 26413.3 with a remaining 0.0.
