We divide 180810 by 66
The aim is to understand the frequency of 66 in 180810.

Let's proceed to step 1:
If we divide 1 by 66, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 66

Step 2:
18 divided by 66 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 66

Step 3:
66 can be fit into 180 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 132 from 180, we get 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 66

On to step 4:
488 divided by 66 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 26 after subtracting 462 from 488.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 66

Moving on to step 5:
66 goes into 261 3 times with a remainder of 63.
The next digit of our result is 3. 
Result so far: 273.0
If we take 198 away from 261, we end up with 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 66

On to step 6:
66 can be fit into 630 9 times, resulting in a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 2739.0
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
When dividing 360 by 66, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2739.5
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 66, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 2739.54
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2739.545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 2739.5454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
If we divide 360 by 66, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 2739.54545
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
66 goes into 300 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 2739.545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
66 goes into 360 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2739.5454545
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
66 goes into 300 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 2739.54545454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 2739.54545454, and the remainder is 3.6e-08.
