We divide 820003 by 30
The aim is to understand the frequency of 30 in 820003.

Moving on to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 30

Let's proceed to step 2:
The number 30 fits into 82 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 2.0
If we take 60 away from 82, we end up with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 30

Let's proceed to step 3:
220 divided by 30 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 210 from 220 leaves us with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 30

Step 4:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 273.0
The remainder is 10 after subtracting 90 from 100.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 30

Step 5:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 2733.0
If we take 90 away from 100, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 30

Advancing to step 6:
If we divide 103 by 30, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 27333.0
If we subtract 90 from 103, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 30 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 27333.4
Subtracting 120 from 130 leaves us 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 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 27333.43
If we subtract 90 from 100, we get 10.
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 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 27333.433
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 27333.433 with a remainder of 0.001.
