11668649 ÷ 539 
The aim is to understand the frequency of 539 in 11668649.

Let's proceed to step 1:
If we divide 1 by 539, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 539

Advancing to step 2:
When dividing 11 by 539, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 539

Going ahead to step 3:
539 goes into 116 0 times with a remainder of 116.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 116 after subtracting 0 from 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 539

On to step 4:
If we divide 1166 by 539, we get 2 and a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1078 away from 1166, we end up with 88.
Bring next digit (8) of the dividend behind the 88 and repeat the process: 888 / 539

Let's proceed to step 5:
888 divided by 539 is 1 with a remainder of 349.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 539 from 888 and we're left with 349.
Fetch the next digit (6) from the dividend, attach it to 349 and continue: 3496 / 539

Moving on to step 6:
When dividing 3496 by 539, we get 6 with a remainder of 262.
The next digit of our result is 6. 
Result so far: 216.0
Deduct 3234 from 3496 and we're left with 262.
Grab the next digit (4) from the dividend, add it to 262, then carry on: 2624 / 539

Going ahead to step 7:
539 can be fit into 2624 4 times, resulting in a remainder of 468.
The next digit of our result is 4. 
Result so far: 2164.0
Subtracting 2156 from 2624 leaves us with 468.
Append the next digit (9) from the dividend to 468 and continue with: 4689 / 539

Let's proceed to step 8:
If we divide 4689 by 539, we get 8 and a remainder of 377.
The next digit of our result is 8. 
Result so far: 21648.0
If we take 4312 away from 4689, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 9:
When dividing 3770 by 539, we get 6 with a remainder of 536.
The number 6 becomes the next digit in our result. 
Result so far: 21648.6
If we subtract 3234 from 3770, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 10:
If we divide 5360 by 539, we get 9 and a remainder of 509.
The number 9 becomes the next digit in our result. 
Result so far: 21648.69
If we take 4851 away from 5360, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 11:
5090 divided by 539 is 9 with a remainder of 239.
The number 9 becomes the next digit in our result. 
Result so far: 21648.699
Subtracting 4851 from 5090 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The final result is 21648.699 with a remainder of 0.0239.
