We're dividing 52138 by 33 
The aim is to understand the frequency of 33 in 52138.

Advancing to step 1:
5 divided by 33 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 33

Going ahead to step 2:
33 can be fit into 52 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 33 from 52 to get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 33

Step 3:
The number 33 fits into 191 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 165 from 191, we get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 33

Let's proceed to step 4:
33 goes into 263 7 times with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
If we subtract 231 from 263, we get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 33

Moving on to step 5:
When dividing 328 by 33, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 1579.0
The remainder is 31 after subtracting 297 from 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 6:
If we divide 310 by 33, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1579.9
The remainder is 13 after subtracting 297 from 310.
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 7:
33 can be fit into 130 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1579.93
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.

Going ahead to step 8:
33 can be fit into 310 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1579.939
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.

On to step 9:
130 divided by 33 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1579.9393
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.

Let's proceed to step 10:
33 goes into 310 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1579.93939
The remainder is 13 after subtracting 297 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
33 can be fit into 130 3 times, resulting in a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 1579.939393
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.

On to step 12:
If we divide 310 by 33, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 1579.9393939
The remainder is 13 after subtracting 297 from 310.
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 13:
33 goes into 130 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 1579.93939393
If we subtract 99 from 130, we 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.

The final result is 1579.93939393 with a remainder of 3.1e-08.
