We look at the division of 131955 by 33 
The aim is to understand the frequency of 33 in 131955.

Moving on to step 1:
When dividing 1 by 33, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 33

Going ahead to step 2:
33 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 33

Moving on to step 3:
If we divide 131 by 33, we get 3 and a remainder of 32.
The next digit of our result is 3. 
Result so far: 3.0
If we take 99 away from 131, we end up with 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 33

Going ahead to step 4:
33 can be fit into 329 9 times, resulting in a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 297 from 329 leaves us with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 33

Going ahead to step 5:
When dividing 325 by 33, we get 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 399.0
Subtract 297 from 325 to get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 33

Advancing to step 6:
285 divided by 33 is 8 with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 3998.0
Subtract 264 from 285 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
210 divided by 33 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3998.6
Subtracting 198 from 210 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
33 can be fit into 120 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3998.63
Subtract 99 from 120 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 33, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3998.636
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 33, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3998.6363
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
33 goes into 210 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 3998.63636
Deduct 198 from 210 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
33 goes into 120 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3998.636363
Subtract 99 from 120 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
33 goes into 210 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 3998.6363636
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
The number 33 fits into 120 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3998.63636363
Deduct 99 from 120 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 3998.63636363 with a remaining 2.1e-08.
