Let's divide 253280 by 30
The aim is to understand the frequency of 30 in 253280.

Going ahead to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 30

Advancing to step 2:
If we divide 25 by 30, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 30

On to step 3:
The number 30 fits into 253 8 times, leaving a remainder of 13.
The next digit of our result is 8. 
Result so far: 8.0
If we take 240 away from 253, we end up with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 30

Let's proceed to step 4:
The number 30 fits into 132 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 120 from 132, we get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 30

Going ahead to step 5:
The number 30 fits into 128 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 844.0
Deduct 120 from 128 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 30

Advancing to step 6:
The number 30 fits into 80 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 8442.0
The remainder is 20 after subtracting 60 from 80.
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 7:
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: 8442.6
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.

Going ahead to step 8:
200 divided by 30 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 8442.66
Subtracting 180 from 200 leaves us 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.

Our division results in 8442.66 with a remaining 0.02.
