We look at the division of 419461 by 30 
The aim is to understand the frequency of 30 in 419461.

Let's proceed to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 30

Moving on to step 2:
41 divided by 30 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 30 from 41 leaves us with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 30

Going ahead to step 3:
119 divided by 30 is 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 90 from 119, we get 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 30

Going ahead to step 4:
294 divided by 30 is 9 with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
The remainder is 24 after subtracting 270 from 294.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 30

Let's proceed to step 5:
246 divided by 30 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 1398.0
If we take 240 away from 246, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 30

Moving on to step 6:
30 goes into 61 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 13982.0
The remainder is 1 after subtracting 60 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
30 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13982.0
The remainder is 10 after subtracting 0 from 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 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 13982.03
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.

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: 13982.033
If we take 90 away from 100, we end up 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.

The quotient of the division is 13982.033, and the remainder is 0.001.
