We divide 812084 by 30
The aim is to understand the frequency of 30 in 812084.

On to step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 30

Let's proceed to step 2:
The number 30 fits into 81 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 60 from 81 leaves us with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 30

Moving on to step 3:
When dividing 212 by 30, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 210 from 212 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 30

Step 4:
The number 30 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 270.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 30

On to step 5:
When dividing 208 by 30, we get 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 2706.0
The remainder is 28 after subtracting 180 from 208.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 30

On to step 6:
When dividing 284 by 30, we get 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 27069.0
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:
The number 30 fits into 140 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 27069.4
If we take 120 away from 140, 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.

Moving on to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 27069.46
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:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 27069.466
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.

After the division, we end up with 27069.466 and a remainder of 0.002.
