We divide 478277 by 30
The aim is to understand the frequency of 30 in 478277.

Going ahead to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 30

Step 2:
The number 30 fits into 47 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 30 from 47.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 30

Let's proceed to step 3:
30 goes into 178 5 times with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 28 after subtracting 150 from 178.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 30

Going ahead to step 4:
If we divide 282 by 30, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Deduct 270 from 282 and we're left with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 30

Advancing to step 5:
The number 30 fits into 127 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 1594.0
If we take 120 away from 127, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 30

Let's proceed to step 6:
30 can be fit into 77 2 times, resulting in a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 15942.0
The remainder is 17 after subtracting 60 from 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 30 fits into 170 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 15942.5
If we subtract 150 from 170, 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.

Let's proceed to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 15942.56
Subtract 180 from 200 to 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.

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: 15942.566
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.

The final result is 15942.566 with a remainder of 0.002.
