We're dividing 317684 by 66 
The aim is to understand the frequency of 66 in 317684.

Advancing to step 1:
If we divide 3 by 66, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 66

Going ahead to step 2:
If we divide 31 by 66, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 66

Let's proceed to step 3:
When dividing 317 by 66, we get 4 with a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 264 away from 317, we end up with 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 66

Advancing to step 4:
66 goes into 536 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 528 from 536 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 66

Moving on to step 5:
66 goes into 88 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 481.0
Subtract 66 from 88 to get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 66

Step 6:
66 can be fit into 224 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 4813.0
Subtract 198 from 224 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 4813.3
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 66, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 4813.39
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
If we divide 260 by 66, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 4813.393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
620 divided by 66 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 4813.3939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
260 divided by 66 is 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 4813.39393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
If we divide 620 by 66, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 4813.393939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
66 goes into 260 3 times with a remainder of 62.
The next digit of our result is 3. 
Result so far: 4813.3939393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
66 goes into 620 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 4813.39393939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 4813.39393939 with a balance of 2.6e-08.
