Let's divide 33981 by 33
The aim is to understand the frequency of 33 in 33981.

On to step 1:
3 divided by 33 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 33

Moving on to step 2:
If we divide 33 by 33, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 33 from 33 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 33

Going ahead to step 3:
If we divide 9 by 33, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 33

Step 4:
33 goes into 98 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we take 66 away from 98, we end up with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 33

Advancing to step 5:
When dividing 321 by 33, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 1029.0
Deduct 297 from 321 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 6:
33 can be fit into 240 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1029.7
Deduct 231 from 240 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 33 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1029.72
If we subtract 66 from 90, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
When dividing 240 by 33, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 1029.727
Subtract 231 from 240 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 33, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1029.7272
The remainder is 24 after subtracting 66 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
The number 33 fits into 240 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 1029.72727
If we take 231 away from 240, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
The number 33 fits into 90 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1029.727272
The remainder is 24 after subtracting 66 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 33, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 1029.7272727
The remainder is 9 after subtracting 231 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
The number 33 fits into 90 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1029.72727272
Subtracting 66 from 90 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1029.72727272 and a remainder of 2.4e-08.
