800728 divided by 30 
The aim is to understand the frequency of 30 in 800728.

On to step 1:
8 divided by 30 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 30

Moving on to step 2:
The number 30 fits into 80 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 60 from 80 leaves us with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 30

Going ahead to step 3:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 180 from 200, we get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 30

Step 4:
30 goes into 207 6 times with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 266.0
Deduct 180 from 207 and we're left with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 30

Moving on to step 5:
If we divide 272 by 30, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 2669.0
If we subtract 270 from 272, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 30

On to step 6:
30 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 26690.0
The remainder is 28 after subtracting 0 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
When dividing 280 by 30, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 26690.9
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 26690.93
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 26690.933
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 26690.933 with a balance of 0.001.
