Let's divide 585559 by 15
We're looking to find how many times 15 goes into 585559.

Let's proceed to step 1:
5 divided by 15 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 15

Let's proceed to step 2:
The number 15 fits into 58 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 45 from 58 and we're left with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 15

Let's proceed to step 3:
135 divided by 15 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 135 from 135 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 15

On to step 4:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 390.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 15

Step 5:
55 divided by 15 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3903.0
If we subtract 45 from 55, we get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 15

Step 6:
15 can be fit into 109 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 39037.0
Subtracting 105 from 109 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 15 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 39037.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 39037.26
Subtracting 90 from 100 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 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 39037.266
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 39037.266, with a leftover of 0.001.
