We look at the division of 66409923 by 270 
The aim is to understand the frequency of 270 in 66409923.

Let's proceed to step 1:
If we divide 6 by 270, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 270

Advancing to step 2:
270 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 270

On to step 3:
The number 270 fits into 664 2 times, leaving a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 540 from 664 to get 124.
Take the next digit (0) from the dividend and append it to 124, then repeat: 1240 / 270

Advancing to step 4:
The number 270 fits into 1240 4 times, leaving a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtracting 1080 from 1240 leaves us with 160.
Include the next digit (9) from the dividend after 160, then repeat: 1609 / 270

Step 5:
The number 270 fits into 1609 5 times, leaving a remainder of 259.
Write down 5 as next digit of the result. 
Result so far: 245.0
If we take 1350 away from 1609, we end up with 259.
Fetch the next digit (9) from the dividend, attach it to 259 and continue: 2599 / 270

Let's proceed to step 6:
2599 divided by 270 is 9 with a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 2459.0
Subtract 2430 from 2599 to get 169.
Include the next digit (2) from the dividend after 169, then repeat: 1692 / 270

Moving on to step 7:
The number 270 fits into 1692 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 24596.0
If we take 1620 away from 1692, we end up with 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 270

Advancing to step 8:
723 divided by 270 is 2 with a remainder of 183.
The next digit of our result is 2. 
Result so far: 245962.0
The remainder is 183 after subtracting 540 from 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
The number 270 fits into 1830 6 times, leaving a remainder of 210.
Record the quotient 6 as the next digit in the result. 
Result so far: 245962.6
The remainder is 210 after subtracting 1620 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
The number 270 fits into 2100 7 times, leaving a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 245962.67
Subtracting 1890 from 2100 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 11:
2100 divided by 270 is 7 with a remainder of 210.
The next digit of our result is 7. 
Result so far: 245962.677
The remainder is 210 after subtracting 1890 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 245962.677 with a remainder of 0.021.
