We divide 223973 by 30
The aim is to understand the frequency of 30 in 223973.

Moving on to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 30

Let's proceed to step 2:
If we divide 22 by 30, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 30

Step 3:
30 can be fit into 223 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 13 after subtracting 210 from 223.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 30

Moving on to step 4:
The number 30 fits into 139 4 times, leaving a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 120 from 139 to get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 30

On to step 5:
The number 30 fits into 197 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 746.0
Deduct 180 from 197 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 30

On to step 6:
If we divide 173 by 30, we get 5 and a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 7465.0
If we take 150 away from 173, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
When dividing 230 by 30, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 7465.7
Subtracting 210 from 230 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 7465.76
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 7465.766
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 7465.766 with a remaining 0.002.
