324627 ÷ 66 
The aim is to understand the frequency of 66 in 324627.

On to step 1:
3 divided by 66 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 66

Advancing to step 2:
The number 66 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 66

Step 3:
When dividing 324 by 66, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 264 from 324 and we're left with 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 66

Step 4:
If we divide 606 by 66, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 594 from 606 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 66

On to step 5:
66 goes into 122 1 times with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 491.0
If we take 66 away from 122, we end up with 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 66

Step 6:
The number 66 fits into 567 8 times, leaving a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 4918.0
If we subtract 528 from 567, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
66 can be fit into 390 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 4918.5
Subtract 330 from 390 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
If we divide 600 by 66, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 4918.59
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 66, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4918.59
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 4918.5909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 4918.5909
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 66 fits into 600 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 4918.590909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4918.590909
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
600 divided by 66 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4918.59090909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 4918.59090909 with a remaining 6e-09.
