894478 ÷ 30 
The aim is to understand the frequency of 30 in 894478.

Moving 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
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 30

On to step 2:
30 goes into 89 2 times with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 60 away from 89, we end up with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 30

Going ahead to step 3:
294 divided by 30 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 270 away from 294, we end up with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 30

Advancing to step 4:
244 divided by 30 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 298.0
Subtract 240 from 244 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 30

On to step 5:
If we divide 47 by 30, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 2981.0
If we subtract 30 from 47, we get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 30

Advancing to step 6:
When dividing 178 by 30, we get 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 29815.0
Subtracting 150 from 178 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
280 divided by 30 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 29815.9
Subtract 270 from 280 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.

On to step 8:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 29815.93
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
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: 29815.933
If we subtract 90 from 100, we 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.

After the division, we end up with 29815.933 and a remainder of 0.001.
