Let's divide 164578 by 30
The aim is to understand the frequency of 30 in 164578.

Moving on to step 1:
30 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 30

Advancing to step 2:
30 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 30

Let's proceed to step 3:
30 can be fit into 164 5 times, resulting in a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 150 from 164 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 30

Let's proceed to step 4:
The number 30 fits into 145 4 times, leaving a remainder of 25.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 120 from 145 to get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 30

Step 5:
If we divide 257 by 30, we get 8 and a remainder of 17.
The next digit of our result is 8. 
Result so far: 548.0
Deduct 240 from 257 and we're left with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 30

Advancing to step 6:
The number 30 fits into 178 5 times, leaving a remainder of 28.
The next digit of our result is 5. 
Result so far: 5485.0
If we take 150 away from 178, we end up 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.

On to step 7:
30 can be fit into 280 9 times, resulting in a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 5485.9
Subtracting 270 from 280 leaves us 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:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 5485.93
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.

Going ahead to step 9:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 5485.933
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.

The final result is 5485.933 with a remainder of 0.001.
