Let's divide 307403 by 66
The aim is to understand the frequency of 66 in 307403.

Moving on to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 66

Moving on to step 2:
66 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 66

Step 3:
66 goes into 307 4 times with a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 264 from 307 and we're left with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 66

Advancing to step 4:
434 divided by 66 is 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 396 away from 434, we end up with 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 66

Going ahead to step 5:
66 goes into 380 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 465.0
If we subtract 330 from 380, we get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 66

On to step 6:
If we divide 503 by 66, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 4657.0
If we take 462 away from 503, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
66 goes into 410 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 4657.6
Subtract 396 from 410 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
When dividing 140 by 66, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4657.62
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 4657.621
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
66 goes into 140 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 4657.6212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
80 divided by 66 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 4657.62121
Subtract 66 from 80 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 66, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4657.621212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
If we divide 80 by 66, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 4657.6212121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
When dividing 140 by 66, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4657.62121212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 4657.62121212 with a remainder of 8e-09.
