We divide 512864 by 1
Let's see how many times 1 fits into 512864.

Moving on to step 1:
1 goes into 5 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 5 from 5 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 2:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 1 from 1, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Step 3:
When dividing 2 by 1, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 512.0
If we take 2 away from 2, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 5128.0
If we take 8 away from 8, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Advancing to step 5:
When dividing 6 by 1, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 51286.0
Subtract 6 from 6 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Let's proceed to step 6:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 512864.0
Subtracting 4 from 4 leaves us 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.

On to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 512864.0
Subtracting 0 from 0 leaves us 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.
Put 0 as the next digit of the answer. 
Result so far: 512864.0
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.

Our division results in 512864.0 with a remaining 0.0.
