603587 ÷ 33 
The aim is to understand the frequency of 33 in 603587.

Moving on to step 1:
33 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 33

Moving on to step 2:
33 goes into 60 1 times with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 33 away from 60, we end up with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 33

Moving on to step 3:
33 goes into 273 8 times with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 264 from 273 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 33

Moving on to step 4:
If we divide 95 by 33, we get 2 and a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 182.0
Subtracting 66 from 95 leaves us with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 33

Going ahead to step 5:
If we divide 298 by 33, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1829.0
Subtract 297 from 298 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 33

Advancing to step 6:
If we divide 17 by 33, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 18290.0
Subtracting 0 from 17 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
33 can be fit into 170 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18290.5
If we subtract 165 from 170, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 33, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 18290.51
If we subtract 33 from 50, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
When dividing 170 by 33, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18290.515
The remainder is 5 after subtracting 165 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
33 goes into 50 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 18290.5151
Subtracting 33 from 50 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
33 goes into 170 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 18290.51515
Subtracting 165 from 170 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
50 divided by 33 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 18290.515151
Subtract 33 from 50 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
33 can be fit into 170 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 18290.5151515
Subtract 165 from 170 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
The number 33 fits into 50 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 18290.51515151
Subtract 33 from 50 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 18290.51515151, with a leftover of 1.7e-08.
