We're dividing 570661 by 33 
The aim is to understand the frequency of 33 in 570661.

Let's proceed to step 1:
33 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 33

Moving on to step 2:
The number 33 fits into 57 1 times, leaving a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 33 from 57, we get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 33

Step 3:
When dividing 240 by 33, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 231 from 240 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 33

Advancing to step 4:
If we divide 96 by 33, we get 2 and a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 172.0
Deduct 66 from 96 and we're left with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 33

Moving on to step 5:
33 goes into 306 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 1729.0
Deduct 297 from 306 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 33

Step 6:
33 goes into 91 2 times with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 17292.0
Subtracting 66 from 91 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
When dividing 250 by 33, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 17292.7
Subtracting 231 from 250 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
33 can be fit into 190 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 17292.75
Deduct 165 from 190 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
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: 17292.757
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
190 divided by 33 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 17292.7575
Subtract 165 from 190 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
250 divided by 33 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 17292.75757
If we subtract 231 from 250, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
33 goes into 190 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 17292.757575
The remainder is 25 after subtracting 165 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
33 goes into 250 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 17292.7575757
Subtracting 231 from 250 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
When dividing 190 by 33, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 17292.75757575
Subtracting 165 from 190 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 17292.75757575 with a remaining 2.5e-08.
