We're dividing 417585 by 30 
Let's see how many times 30 fits into 417585.

Let's proceed to step 1:
30 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 30

On to step 2:
30 goes into 41 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 30 from 41 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 30

On to step 3:
The number 30 fits into 117 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 27 after subtracting 90 from 117.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 30

On to step 4:
When dividing 275 by 30, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we take 270 away from 275, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 30

Let's proceed to step 5:
30 can be fit into 58 1 times, resulting in a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1391.0
Subtract 30 from 58 to get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 30

Moving on to step 6:
If we divide 285 by 30, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 13919.0
Subtract 270 from 285 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
150 divided by 30 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13919.5
Deduct 150 from 150 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13919.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
30 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13919.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 13919.5 with a remaining 0.0.
