Let's divide 810321 by 33
The aim is to understand the frequency of 33 in 810321.

Moving on to step 1:
33 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
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

Step 2:
When dividing 81 by 33, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 66 away from 81, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 33

Step 3:
33 goes into 150 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 132 from 150 to get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 33

Advancing to step 4:
The number 33 fits into 183 5 times, leaving a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 245.0
The remainder is 18 after subtracting 165 from 183.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 33

Step 5:
33 goes into 182 5 times with a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 2455.0
Subtracting 165 from 182 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 33

Moving on to step 6:
33 goes into 171 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 24555.0
The remainder is 6 after subtracting 165 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 33 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 24555.1
The remainder is 27 after subtracting 33 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
33 goes into 270 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 24555.18
The remainder is 6 after subtracting 264 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
33 can be fit into 60 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 24555.181
If we subtract 33 from 60, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
33 goes into 270 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 24555.1818
If we subtract 264 from 270, we get 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 11:
The number 33 fits into 60 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 24555.18181
If we subtract 33 from 60, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
When dividing 270 by 33, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 24555.181818
Subtract 264 from 270 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
33 can be fit into 60 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 24555.1818181
Subtract 33 from 60 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 14:
33 can be fit into 270 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 24555.18181818
Subtract 264 from 270 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 24555.18181818, with a leftover of 6e-09.
