We look at the division of 188041 by 66 
The aim is to understand the frequency of 66 in 188041.

Let's proceed to step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 66

On to step 2:
The number 66 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 66

Step 3:
66 goes into 188 2 times with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 132 from 188 to get 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 66

Advancing to step 4:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 528 from 560, we get 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 66

On to step 5:
66 goes into 324 4 times with a remainder of 60.
The next digit of our result is 4. 
Result so far: 284.0
The remainder is 60 after subtracting 264 from 324.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 66

On to step 6:
If we divide 601 by 66, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2849.0
The remainder is 7 after subtracting 594 from 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
66 can be fit into 70 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 2849.1
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 66 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2849.1
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 66, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 2849.106
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 66, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2849.106
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 66, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2849.10606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 66, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2849.10606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
If we divide 400 by 66, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2849.1060606
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 2849.1060606
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 2849.1060606 with a remainder of 4e-08.
