584386 ÷ 15 
Let's see how many times 15 fits into 584386.

Going ahead to step 1:
5 divided by 15 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 15

Step 2:
15 can be fit into 58 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 45 from 58 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 15

Moving on to step 3:
15 goes into 134 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 120 from 134 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 15

Moving on to step 4:
The number 15 fits into 143 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 389.0
If we take 135 away from 143, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 15

Going ahead to step 5:
15 goes into 88 5 times with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 3895.0
If we take 75 away from 88, we end up with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 15

Let's proceed to step 6:
If we divide 136 by 15, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 38959.0
Subtract 135 from 136 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
15 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 38959.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 38959.06
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 38959.066
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 38959.066 and a remainder of 0.001.
