We're dividing 300587 by 1 
We want to divide 300587 by 1.

On to step 1:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Moving on to step 3:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 300.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

On to step 4:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3005.0
Deduct 5 from 5 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Going ahead to step 5:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 30058.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Going ahead to step 6:
1 goes into 7 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 300587.0
If we take 7 away from 7, 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.

Advancing to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 300587.0
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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 300587.0
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.

After the division, we end up with 300587.0 and a remainder of 0.0.
