We look at the division of 815692 by 33 
The aim is to understand the frequency of 33 in 815692.

Going ahead to step 1:
33 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 33

Moving on to step 2:
81 divided by 33 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 66 from 81 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 33

Let's proceed to step 3:
33 can be fit into 155 4 times, resulting in a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 132 from 155, we get 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 33

On to step 4:
The number 33 fits into 236 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 247.0
Deduct 231 from 236 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 33

Moving on to step 5:
If we divide 59 by 33, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 2471.0
Deduct 33 from 59 and we're left with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 33

Advancing to step 6:
33 can be fit into 262 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 24717.0
If we take 231 away from 262, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
If we divide 310 by 33, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 24717.9
Subtracting 297 from 310 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
When dividing 130 by 33, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 24717.93
The remainder is 31 after subtracting 99 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
When dividing 310 by 33, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 24717.939
Deduct 297 from 310 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
130 divided by 33 is 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 24717.9393
Subtracting 99 from 130 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
33 goes into 310 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 24717.93939
Subtracting 297 from 310 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
When dividing 130 by 33, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 24717.939393
If we take 99 away from 130, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
33 goes into 310 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 24717.9393939
Deduct 297 from 310 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
130 divided by 33 is 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 24717.93939393
Deduct 99 from 130 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 24717.93939393 with a remaining 3.1e-08.
