366490 divided by 30 
The aim is to understand the frequency of 30 in 366490.

Moving on to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 30

Advancing to step 2:
If we divide 36 by 30, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 6 after subtracting 30 from 36.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 30

On to step 3:
When dividing 66 by 30, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 60 from 66 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 30

On to step 4:
When dividing 64 by 30, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 60 from 64 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 30

Let's proceed to step 5:
If we divide 49 by 30, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1221.0
Deduct 30 from 49 and we're left with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 30

Step 6:
The number 30 fits into 190 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 12216.0
If we take 180 away from 190, 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.

Let's proceed to step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 12216.3
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.

On to step 8:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 12216.33
Deduct 90 from 100 and we're left 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 final result is 12216.33 with a remainder of 0.01.
