We're dividing 853340 by 30 
The aim is to understand the frequency of 30 in 853340.

Going ahead to step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 30

Advancing to step 2:
85 divided by 30 is 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 60 from 85 leaves us with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 30

Advancing to step 3:
30 can be fit into 253 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 240 from 253 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 30

Advancing to step 4:
The number 30 fits into 133 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 284.0
If we take 120 away from 133, we end up with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 30

Advancing to step 5:
134 divided by 30 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 2844.0
Deduct 120 from 134 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 30

Let's proceed to step 6:
30 goes into 140 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 28444.0
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.

Moving on to step 7:
When dividing 200 by 30, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 28444.6
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.

Going ahead to step 8:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 28444.66
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.

The final outcome is 28444.66, with a leftover of 0.02.
