We divide 66453739 by 33
The aim is to understand the frequency of 33 in 66453739.

Step 1:
The number 33 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 33

On to step 2:
The number 33 fits into 66 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 66 from 66 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 33

Let's proceed to step 3:
33 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 33

On to step 4:
45 divided by 33 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Subtracting 33 from 45 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 33

Let's proceed to step 5:
33 goes into 123 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 2013.0
If we subtract 99 from 123, we get 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 33

Step 6:
If we divide 247 by 33, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 20137.0
Subtract 231 from 247 to get 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 33

Going ahead to step 7:
33 can be fit into 163 4 times, resulting in a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 201374.0
The remainder is 31 after subtracting 132 from 163.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 33

On to step 8:
33 can be fit into 319 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 2013749.0
Subtract 297 from 319 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
When dividing 220 by 33, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 2013749.6
Subtract 198 from 220 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 33, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 2013749.66
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 2013749.66 with a balance of 0.022.
