We look at the division of 574284 by 33 
The aim is to understand the frequency of 33 in 574284.

Moving on to step 1:
The number 33 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 33

Step 2:
If we divide 57 by 33, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 33 from 57 to get 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 33

Going ahead to step 3:
33 goes into 244 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 13 after subtracting 231 from 244.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 33

Step 4:
33 can be fit into 132 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 174.0
Subtract 132 from 132 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 33

Advancing to step 5:
33 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 1740.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 33

Step 6:
If we divide 84 by 33, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 17402.0
If we subtract 66 from 84, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
When dividing 180 by 33, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 17402.5
If we subtract 165 from 180, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
33 goes into 150 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 17402.54
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
33 can be fit into 180 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 17402.545
The remainder is 15 after subtracting 165 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
33 goes into 150 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 17402.5454
If we subtract 132 from 150, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
If we divide 180 by 33, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 17402.54545
Deduct 165 from 180 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
33 goes into 150 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 17402.545454
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
180 divided by 33 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 17402.5454545
Subtract 165 from 180 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
33 can be fit into 150 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 17402.54545454
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 17402.54545454 and a remainder of 1.8e-08.
