We look at the division of 407519 by 30 
We want to figure out the number of times 407519 can be divided by 30.

Going ahead to step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 30

Moving on to step 2:
If we divide 40 by 30, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 30 from 40 to get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 30

Advancing to step 3:
30 can be fit into 107 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 90 from 107 and we're left with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 30

On to step 4:
175 divided by 30 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 135.0
If we take 150 away from 175, we end up with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 30

Advancing to step 5:
The number 30 fits into 251 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 1358.0
The remainder is 11 after subtracting 240 from 251.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 30

Let's proceed to step 6:
When dividing 119 by 30, we get 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 13583.0
Subtract 90 from 119 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 13583.9
The remainder is 20 after subtracting 270 from 290.
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.
Put 6 as the next digit of the answer. 
Result so far: 13583.96
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.

On to step 9:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 13583.966
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 13583.966 with a remainder of 0.002.
