We're dividing 305384 by 30 
The aim is to understand the frequency of 30 in 305384.

On to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

On to step 2:
When dividing 30 by 30, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 30 from 30 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 30

Moving on to step 3:
30 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 30

Let's proceed to step 4:
If we divide 53 by 30, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 30 from 53 and we're left with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 30

Advancing to step 5:
When dividing 238 by 30, we get 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
Subtract 210 from 238 to get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 30

Going ahead to step 6:
If we divide 284 by 30, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 10179.0
Subtracting 270 from 284 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
140 divided by 30 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 10179.4
Deduct 120 from 140 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.

Let's proceed to step 8:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 10179.46
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.

Moving on to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 10179.466
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.

In conclusion, the division gives 10179.466 with a balance of 0.002.
