Let's divide 730255 by 66
The aim is to understand the frequency of 66 in 730255.

Advancing to step 1:
When dividing 7 by 66, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 66

Step 2:
The number 66 fits into 73 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 73 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 66

Step 3:
66 can be fit into 70 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 66 from 70 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 66

Moving on to step 4:
66 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 66

Moving on to step 5:
425 divided by 66 is 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 1106.0
If we subtract 396 from 425, we get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 66

Going ahead to step 6:
The number 66 fits into 295 4 times, leaving a remainder of 31.
The next digit of our result is 4. 
Result so far: 11064.0
If we take 264 away from 295, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
The number 66 fits into 310 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 11064.4
Deduct 264 from 310 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
If we divide 460 by 66, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 11064.46
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
66 goes into 640 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 11064.469
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
When dividing 460 by 66, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 11064.4696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 11064.46969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 11064.469696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
66 goes into 640 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 11064.4696969
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 11064.46969696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 11064.46969696 with a remaining 6.4e-08.
