We're dividing 633637 by 30 
The aim is to understand the frequency of 30 in 633637.

Advancing to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 30

Step 2:
The number 30 fits into 63 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 60 from 63 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 30

Step 3:
30 can be fit into 33 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 30 from 33, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 30

Let's proceed to step 4:
30 goes into 36 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Deduct 30 from 36 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 30

Moving on to step 5:
30 goes into 63 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2112.0
The remainder is 3 after subtracting 60 from 63.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 30

Advancing to step 6:
30 goes into 37 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 21121.0
The remainder is 7 after subtracting 30 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 30 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 21121.2
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 21121.23
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 21121.233
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 21121.233 with a remaining 0.001.
