We look at the division of 818396 by 33 
The aim is to understand the frequency of 33 in 818396.

On to step 1:
The number 33 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 33

On to step 2:
When dividing 81 by 33, we get 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 66 from 81 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 33

Advancing to step 3:
33 goes into 158 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 132 from 158 and we're left with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 33

Step 4:
33 goes into 263 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 247.0
If we subtract 231 from 263, we get 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 33

Let's proceed to step 5:
33 goes into 329 9 times with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 2479.0
Subtracting 297 from 329 leaves us with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 33

Step 6:
If we divide 326 by 33, we get 9 and a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 24799.0
If we subtract 297 from 326, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 33 is 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 24799.8
The remainder is 26 after subtracting 264 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
33 can be fit into 260 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 24799.87
Subtract 231 from 260 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
33 goes into 290 8 times with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 24799.878
Subtracting 264 from 290 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.

On to step 10:
If we divide 260 by 33, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 24799.8787
Deduct 231 from 260 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
33 can be fit into 290 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 24799.87878
The remainder is 26 after subtracting 264 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 33 is 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 24799.878787
Deduct 231 from 260 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
If we divide 290 by 33, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 24799.8787878
The remainder is 26 after subtracting 264 from 290.
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 14:
When dividing 260 by 33, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 24799.87878787
Subtracting 231 from 260 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 24799.87878787 with a remainder of 2.9e-08.
