149908 divided by 30 
The aim is to understand the frequency of 30 in 149908.

Advancing to step 1:
If we divide 1 by 30, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 30

Step 2:
30 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 30

Moving on to step 3:
30 goes into 149 4 times with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 120 from 149 and we're left with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 30

On to step 4:
If we divide 299 by 30, we get 9 and a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 270 from 299, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 30

Step 5:
When dividing 290 by 30, we get 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 499.0
Subtract 270 from 290 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 30

On to step 6:
30 can be fit into 208 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 4996.0
If we take 180 away from 208, 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.

Advancing 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: 4996.9
If we subtract 270 from 280, 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.

Moving on to step 8:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 4996.93
Subtracting 90 from 100 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.

Let's proceed to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 4996.933
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.

Our division results in 4996.933 with a remaining 0.001.
