223033 divided by 66 
The aim is to understand the frequency of 66 in 223033.

Going ahead to step 1:
When dividing 2 by 66, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 66

Advancing to step 2:
If we divide 22 by 66, we get 0 and a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 66

Let's proceed to step 3:
The number 66 fits into 223 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 198 away from 223, we end up with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 66

On to step 4:
If we divide 250 by 66, we get 3 and a remainder of 52.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 52 after subtracting 198 from 250.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 66

On to step 5:
66 goes into 523 7 times with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 337.0
Subtract 462 from 523 to get 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 66

On to step 6:
66 goes into 613 9 times with a remainder of 19.
The next digit of our result is 9. 
Result so far: 3379.0
The remainder is 19 after subtracting 594 from 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
66 goes into 190 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 3379.2
Subtract 132 from 190 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.

Advancing to step 8:
66 can be fit into 580 8 times, resulting in a remainder of 52.
The next digit of our result is 8. 
Result so far: 3379.28
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.

Going ahead to step 9:
If we divide 520 by 66, we get 7 and a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 3379.287
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.

Moving on to step 10:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 3379.2878
If we subtract 528 from 580, we 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.

Advancing to step 11:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 3379.28787
Subtracting 462 from 520 leaves us 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.

Moving on to step 12:
When dividing 580 by 66, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 3379.287878
If we subtract 528 from 580, we 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 13:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 3379.2878787
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.

Let's proceed to step 14:
66 can be fit into 580 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 3379.28787878
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 outcome is 3379.28787878, with a leftover of 5.2e-08.
