We're dividing 415823 by 30 
We want to figure out the number of times 415823 can be divided by 30.

Step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 30

On to step 2:
30 can be fit into 41 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 41, we end up with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 30

Step 3:
The number 30 fits into 115 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 90 from 115 leaves us with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 30

Step 4:
258 divided by 30 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Deduct 240 from 258 and we're left with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 30

Let's proceed to step 5:
30 goes into 182 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1386.0
If we take 180 away from 182, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 30

Step 6:
30 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 13860.0
The remainder is 23 after subtracting 0 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
30 can be fit into 230 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 13860.7
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.

Advancing to step 8:
200 divided by 30 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 13860.76
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.

Let's proceed to step 9:
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: 13860.766
If we take 180 away from 200, we end up 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.

The final outcome is 13860.766, with a leftover of 0.002.
