We're dividing 433581 by 30 
The aim is to understand the frequency of 30 in 433581.

Advancing to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 30

Step 2:
43 divided by 30 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 30 from 43 and we're left with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 30

Going ahead to step 3:
30 can be fit into 133 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 120 from 133 leaves us with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 30

Let's proceed to step 4:
When dividing 135 by 30, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 15 after subtracting 120 from 135.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 30

On to step 5:
30 can be fit into 158 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 1445.0
Subtract 150 from 158 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 30

Step 6:
81 divided by 30 is 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 14452.0
Deduct 60 from 81 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
210 divided by 30 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 14452.7
Subtract 210 from 210 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14452.7
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14452.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 14452.7 and a remainder of 0.0.
