We're dividing 300385 by 66 
The aim is to understand the frequency of 66 in 300385.

Let's proceed to step 1:
3 divided by 66 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 66

Moving on to step 2:
The number 66 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 66

Step 3:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 36 after subtracting 264 from 300.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 66

Going ahead to step 4:
66 can be fit into 363 5 times, resulting in a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 330 from 363, we get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 66

On to step 5:
338 divided by 66 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 455.0
If we subtract 330 from 338, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 66

On to step 6:
When dividing 85 by 66, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 4551.0
Subtract 66 from 85 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
66 goes into 190 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 4551.2
Deduct 132 from 190 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
66 goes into 580 8 times with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 4551.28
Subtract 528 from 580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
520 divided by 66 is 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 4551.287
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
If we divide 580 by 66, we get 8 and a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 4551.2878
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
When dividing 520 by 66, we get 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 4551.28787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
66 goes into 580 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 4551.287878
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
66 goes into 520 7 times with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 4551.2878787
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
When dividing 580 by 66, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 4551.28787878
Subtract 528 from 580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 4551.28787878 with a remainder of 5.2e-08.
