We look at the division of 432459 by 30 
The aim is to understand the frequency of 30 in 432459.

Going ahead to step 1:
30 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 30

Step 2:
When dividing 43 by 30, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 43 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 30

Step 3:
When dividing 132 by 30, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 120 from 132 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 30

Step 4:
30 can be fit into 124 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we subtract 120 from 124, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 30

Let's proceed to step 5:
30 can be fit into 45 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1441.0
If we subtract 30 from 45, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 30

On to step 6:
If we divide 159 by 30, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 14415.0
If we take 150 away from 159, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
30 can be fit into 90 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 14415.3
If we take 90 away from 90, we end up 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.

Let's proceed to step 8:
30 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14415.3
If we take 0 away from 0, we end up 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.

Let's proceed to step 9:
30 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14415.3
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.

The quotient of the division is 14415.3, and the remainder is 0.0.
