We're dividing 66485541 by 271 
The aim is to understand the frequency of 271 in 66485541.

Let's proceed to step 1:
The number 271 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 271

Step 2:
271 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 271

Going ahead to step 3:
271 goes into 664 2 times with a remainder of 122.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 122 after subtracting 542 from 664.
Bring next digit (8) of the dividend behind the 122 and repeat the process: 1228 / 271

Going ahead to step 4:
271 can be fit into 1228 4 times, resulting in a remainder of 144.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 1084 from 1228, we get 144.
Take the next digit (5) from the dividend and append it to 144, then repeat: 1445 / 271

Advancing to step 5:
271 can be fit into 1445 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 245.0
If we take 1355 away from 1445, we end up with 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 271

Step 6:
905 divided by 271 is 3 with a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 2453.0
The remainder is 92 after subtracting 813 from 905.
Fetch the next digit (4) from the dividend, attach it to 92 and continue: 924 / 271

Let's proceed to step 7:
271 can be fit into 924 3 times, resulting in a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 24533.0
The remainder is 111 after subtracting 813 from 924.
Take the next digit (1) from the dividend and append it to 111, then repeat: 1111 / 271

Step 8:
1111 divided by 271 is 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 245334.0
The remainder is 27 after subtracting 1084 from 1111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
The number 271 fits into 270 0 times, leaving a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 245334.0
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
When dividing 2700 by 271, we get 9 with a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 245334.09
Deduct 2439 from 2700 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 11:
2610 divided by 271 is 9 with a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 245334.099
If we subtract 2439 from 2610, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

The final result is 245334.099 with a remainder of 0.0171.
