730349 ÷ 30 
The aim is to understand the frequency of 30 in 730349.

Step 1:
7 divided by 30 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 30

Step 2:
The number 30 fits into 73 2 times, leaving a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 60 from 73 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 30

On to step 3:
30 can be fit into 130 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 120 away from 130, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 30

On to step 4:
30 goes into 103 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 243.0
Subtracting 90 from 103 leaves us with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 30

Advancing to step 5:
30 can be fit into 134 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 2434.0
Subtract 120 from 134 to get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 30

Moving on to step 6:
The number 30 fits into 149 4 times, leaving a remainder of 29.
The next digit of our result is 4. 
Result so far: 24344.0
If we subtract 120 from 149, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 24344.9
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 24344.96
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 24344.966
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 24344.966, and the remainder is 0.002.
