We divide 863002 by 30
The aim is to understand the frequency of 30 in 863002.

On to step 1:
30 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 30

Step 2:
86 divided by 30 is 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 60 from 86 to get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 30

Moving on to step 3:
The number 30 fits into 263 8 times, leaving a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 23 after subtracting 240 from 263.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 30

Moving on to step 4:
230 divided by 30 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 287.0
Subtracting 210 from 230 leaves us with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 30

On to step 5:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 2876.0
Deduct 180 from 200 and we're left with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 30

Step 6:
30 can be fit into 202 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 28766.0
If we subtract 180 from 202, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
30 goes into 220 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 28766.7
Subtract 210 from 220 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.

Going ahead to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 28766.73
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.

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: 28766.733
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 28766.733 with a remaining 0.001.
