580305 ÷ 33 
The aim is to understand the frequency of 33 in 580305.

Let's proceed to step 1:
The number 33 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 33

Let's proceed to step 2:
58 divided by 33 is 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 25 after subtracting 33 from 58.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 33

Going ahead to step 3:
If we divide 250 by 33, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 231 from 250 and we're left with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 33

On to step 4:
33 can be fit into 193 5 times, resulting in a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 175.0
Subtract 165 from 193 to get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 33

Moving on to step 5:
33 can be fit into 280 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1758.0
Subtracting 264 from 280 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 33

Going ahead to step 6:
165 divided by 33 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 17585.0
Subtract 165 from 165 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 33 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 17585.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
33 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17585.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 17585.0 and a remainder of 0.0.
