We divide 253265 by 30
The aim is to understand the frequency of 30 in 253265.

Step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 30

Advancing to step 2:
30 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 30

Going ahead 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: 8.0
If we subtract 240 from 253, we get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 30

On to step 4:
When dividing 132 by 30, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 120 from 132 leaves us with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 30

Advancing to step 5:
30 goes into 126 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 844.0
Deduct 120 from 126 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 30

Going ahead to step 6:
30 goes into 65 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 8442.0
If we subtract 60 from 65, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
30 can be fit into 50 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 8442.1
Deduct 30 from 50 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 8:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 8442.16
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.

Let's proceed to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8442.166
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.

The final outcome is 8442.166, with a leftover of 0.002.
