We're dividing 363863 by 30 
We want to figure out the number of times 363863 can be divided by 30.

Moving on to step 1:
3 divided by 30 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 30

Step 2:
36 divided by 30 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 30 from 36 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 30

Moving on to step 3:
The number 30 fits into 63 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 60 from 63, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 30

Moving on to step 4:
30 can be fit into 38 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 121.0
Subtract 30 from 38 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 30

On to step 5:
When dividing 86 by 30, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1212.0
Subtracting 60 from 86 leaves us with 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 30

Moving on to step 6:
The number 30 fits into 263 8 times, leaving a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 12128.0
If we subtract 240 from 263, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
30 can be fit into 230 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 12128.7
The remainder is 20 after subtracting 210 from 230.
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 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 12128.76
Deduct 180 from 200 and we're left 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.

Going ahead to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 12128.766
Subtracting 180 from 200 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.

After the division, we end up with 12128.766 and a remainder of 0.002.
