We're dividing 418508 by 30 
We're looking to find how many times 30 goes into 418508.

On to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 30

Moving on to step 2:
41 divided by 30 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 30 away from 41, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 30

Step 3:
When dividing 118 by 30, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 28 after subtracting 90 from 118.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 30

Going ahead to step 4:
When dividing 285 by 30, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 139.0
If we subtract 270 from 285, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 30

Going ahead to step 5:
30 goes into 150 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1395.0
Deduct 150 from 150 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 30

Let's proceed to step 6:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 13950.0
If we subtract 0 from 8, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 30, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 13950.2
The remainder is 20 after subtracting 60 from 80.
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:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 13950.26
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.

Going ahead to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 13950.266
If we subtract 180 from 200, we 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.

The final result is 13950.266 with a remainder of 0.002.
