Let's divide 853789 by 33
The aim is to understand the frequency of 33 in 853789.

Step 1:
8 divided by 33 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 33

Going ahead to step 2:
33 can be fit into 85 2 times, resulting in a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 66 from 85 leaves us with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 33

Let's proceed to step 3:
The number 33 fits into 193 5 times, leaving a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 165 away from 193, we end up with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 33

Going ahead to step 4:
287 divided by 33 is 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
If we subtract 264 from 287, we get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 33

Going ahead to step 5:
When dividing 238 by 33, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 2587.0
If we subtract 231 from 238, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 33

Going ahead to step 6:
If we divide 79 by 33, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 25872.0
If we subtract 66 from 79, we get 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 7:
33 goes into 130 3 times with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 25872.3
Subtract 99 from 130 to get 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 8:
When dividing 310 by 33, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 25872.39
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 9:
33 can be fit into 130 3 times, resulting in a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 25872.393
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.

Step 10:
33 can be fit into 310 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 25872.3939
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.

Going ahead to step 11:
130 divided by 33 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 25872.39393
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.

On to step 12:
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: 25872.393939
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 13:
When dividing 130 by 33, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 25872.3939393
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.

Moving on to step 14:
33 can be fit into 310 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 25872.39393939
If we subtract 297 from 310, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 25872.39393939 and a remainder of 1.3e-08.
