Let's divide 256563 by 2
Let's see how many times 2 fits into 256563.

Step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Step 2:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 4 from 5 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Let's proceed to step 3:
If we divide 16 by 2, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we subtract 16 from 16, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Moving on to step 4:
If we divide 5 by 2, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 1282.0
Subtract 4 from 5 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Moving on to step 5:
If we divide 16 by 2, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 12828.0
Subtracting 16 from 16 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Let's proceed to step 6:
If we divide 3 by 2, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 128281.0
Deduct 2 from 3 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 128281.5
If we subtract 10 from 10, 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 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 128281.5
The remainder is 0 after subtracting 0 from 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 9:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 128281.5
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 128281.5 with a remaining 0.0.
