378563 ÷ 2 
We're looking to find how many times 2 goes into 378563.

Going ahead to step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 2 away from 3, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

On to step 2:
2 goes into 17 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 16 from 17 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Going ahead to step 3:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 189.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Advancing to step 4:
When dividing 5 by 2, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 1892.0
If we subtract 4 from 5, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Going ahead to step 5:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18928.0
The remainder is 0 after subtracting 16 from 16.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Let's proceed to step 6:
3 divided by 2 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 189281.0
If we take 2 away from 3, we end up 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.

Let's proceed to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 189281.5
If we take 10 away from 10, 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.

Going ahead to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 189281.5
Subtract 0 from 0 to 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.

Moving on to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 189281.5
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 189281.5 with a remainder of 0.0.
