580777 divided by 15 
We want to figure out the number of times 580777 can be divided by 15.

Moving on to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 15

Let's proceed to step 2:
58 divided by 15 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 45 from 58 and we're left with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 15

Going ahead to step 3:
15 goes into 130 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Deduct 120 from 130 and we're left with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 15

Let's proceed to step 4:
107 divided by 15 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 387.0
Deduct 105 from 107 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 15

Going ahead to step 5:
15 can be fit into 27 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 3871.0
If we take 15 away from 27, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 15

Moving on to step 6:
If we divide 127 by 15, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 38718.0
Subtracting 120 from 127 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 15 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 38718.4
If we subtract 60 from 70, 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.

Advancing to step 8:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 38718.46
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.

Let's proceed to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 38718.466
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 result is 38718.466 with a remainder of 0.001.
