We look at the division of 77812665 by 33 
The aim is to understand the frequency of 33 in 77812665.

Advancing to step 1:
If we divide 7 by 33, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 33

Step 2:
33 can be fit into 77 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 66 away from 77, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 33

Let's proceed to step 3:
33 can be fit into 118 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 99 from 118 and we're left with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 33

On to step 4:
If we divide 191 by 33, we get 5 and a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 235.0
If we subtract 165 from 191, we get 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 33

Step 5:
When dividing 262 by 33, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 2357.0
If we take 231 away from 262, we end up with 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 33

On to step 6:
If we divide 316 by 33, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 23579.0
Deduct 297 from 316 and we're left with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 33

Step 7:
If we divide 196 by 33, we get 5 and a remainder of 31.
The next digit of our result is 5. 
Result so far: 235795.0
The remainder is 31 after subtracting 165 from 196.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 33

Let's proceed to step 8:
315 divided by 33 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 2357959.0
The remainder is 18 after subtracting 297 from 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
33 can be fit into 180 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2357959.5
If we take 165 away from 180, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
If we divide 150 by 33, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 2357959.54
If we take 132 away from 150, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
33 goes into 180 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2357959.545
If we take 165 away from 180, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
The number 33 fits into 150 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 2357959.5454
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
The number 33 fits into 180 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2357959.54545
Deduct 165 from 180 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
The number 33 fits into 150 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 2357959.545454
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 15:
33 goes into 180 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 2357959.5454545
If we take 165 away from 180, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 16:
If we divide 150 by 33, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 2357959.54545454
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 2357959.54545454 with a balance of 1.8e-08.
