We're dividing 813907 by 33 
The aim is to understand the frequency of 33 in 813907.

Let's proceed 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
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 33

On to step 2:
33 can be fit into 81 2 times, resulting in a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 66 from 81 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 33

Moving on to step 3:
33 goes into 153 4 times with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 132 from 153 to get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 33

On to step 4:
219 divided by 33 is 6 with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 246.0
Subtracting 198 from 219 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 33

On to step 5:
33 can be fit into 210 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 2466.0
If we subtract 198 from 210, we get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 33

On to step 6:
127 divided by 33 is 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 24663.0
If we subtract 99 from 127, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
The number 33 fits into 280 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 24663.8
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
33 goes into 160 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 24663.84
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
33 can be fit into 280 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 24663.848
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 33 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 24663.8484
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
33 can be fit into 280 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 24663.84848
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
33 can be fit into 160 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 24663.848484
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
33 goes into 280 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 24663.8484848
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
When dividing 160 by 33, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 24663.84848484
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 24663.84848484 with a balance of 2.8e-08.
