478046 divided by 30 
The aim is to understand the frequency of 30 in 478046.

Step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 30

Let's proceed to step 2:
The number 30 fits into 47 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 30 from 47 leaves us with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 30

Step 3:
30 can be fit into 178 5 times, resulting in a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 150 away from 178, we end up with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 30

On to step 4:
The number 30 fits into 280 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 159.0
Deduct 270 from 280 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 30

Moving on to step 5:
When dividing 104 by 30, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 1593.0
If we take 90 away from 104, we end up with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 30

Advancing to step 6:
When dividing 146 by 30, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 15934.0
Subtracting 120 from 146 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
The number 30 fits into 260 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 15934.8
Subtracting 240 from 260 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 15934.86
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 15934.866
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 15934.866 with a remaining 0.002.
