We're dividing 285810 by 1 
We want to figure out the number of times 285810 can be divided by 1.

Advancing to step 1:
2 divided by 1 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 2 from 2, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Let's proceed to step 2:
1 goes into 8 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 3:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 285.0
If we subtract 5 from 5, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Advancing to step 4:
8 divided by 1 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 2858.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 5:
If we divide 1 by 1, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 28581.0
If we subtract 1 from 1, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

On to step 6:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 285810.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 285810.0
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.

Moving on to step 8:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 285810.0
If we take 0 away from 0, we end up 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 285810.0 with a remainder of 0.0.
