804608 ÷ 30 
The aim is to understand the frequency of 30 in 804608.

Advancing to step 1:
If we divide 8 by 30, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 30

Let's proceed to step 2:
30 goes into 80 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 60 from 80 and we're left with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 30

Let's proceed to step 3:
204 divided by 30 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 24 after subtracting 180 from 204.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 30

Going ahead to step 4:
When dividing 246 by 30, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
Deduct 240 from 246 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 30

Moving on to step 5:
60 divided by 30 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2682.0
Subtracting 60 from 60 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 30

On to step 6:
30 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 26820.0
Deduct 0 from 8 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
If we divide 80 by 30, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 26820.2
If we take 60 away from 80, we end up 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.

Advancing to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 26820.26
If we subtract 180 from 200, we 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.

Moving on to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 26820.266
If we take 180 away from 200, we end up 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.

In conclusion, the division gives 26820.266 with a balance of 0.002.
