We're dividing 479786 by 30 
The aim is to understand the frequency of 30 in 479786.

Let's proceed to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 30

Advancing to step 2:
47 divided by 30 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 17 after subtracting 30 from 47.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 30

Let's proceed to step 3:
The number 30 fits into 179 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 29 after subtracting 150 from 179.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 30

Let's proceed to step 4:
If we divide 297 by 30, we get 9 and a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we take 270 away from 297, we end up with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 30

Step 5:
The number 30 fits into 278 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 1599.0
The remainder is 8 after subtracting 270 from 278.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 30

On to step 6:
The number 30 fits into 86 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 15992.0
The remainder is 26 after subtracting 60 from 86.
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:
30 goes into 260 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 15992.8
Deduct 240 from 260 and we're left 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.

Going ahead to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 15992.86
Deduct 180 from 200 and we're left 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.

On to step 9:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 15992.866
If we take 180 away from 200, we end up 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.

The final outcome is 15992.866, with a leftover of 0.002.
