We look at the division of 584490 by 15 
We want to figure out the number of times 584490 can be divided by 15.

Moving on to step 1:
If we divide 5 by 15, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 15

Going ahead to step 2:
If we divide 58 by 15, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
If we take 45 away from 58, we end up with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 15

Let's proceed to step 3:
If we divide 134 by 15, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 120 from 134 to get 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 15

Going ahead to step 4:
15 goes into 144 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 389.0
If we subtract 135 from 144, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 15

Going ahead to step 5:
15 can be fit into 99 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 3896.0
If we subtract 90 from 99, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 15

Step 6:
When dividing 90 by 15, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 38966.0
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 38966.0
Subtracting 0 from 0 leaves us 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:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38966.0
Deduct 0 from 0 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.

The final result is 38966.0 with a remainder of 0.0.
