Let's divide 37003 by 30
The aim is to understand the frequency of 30 in 37003.

Let's proceed to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 30

On to step 2:
The number 30 fits into 37 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 30 away from 37, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 30

Step 3:
When dividing 70 by 30, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 60 from 70 leaves us with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 30

Going ahead to step 4:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we subtract 90 from 100, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 30

Moving on to step 5:
The number 30 fits into 103 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1233.0
Subtract 90 from 103 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 6:
If we divide 130 by 30, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 1233.4
Deduct 120 from 130 and we're left 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.

Let's proceed to step 7:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 1233.43
Subtract 90 from 100 to 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.

On to step 8:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 1233.433
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.

Our division results in 1233.433 with a remaining 0.001.
