Let's divide 378723 by 2
Let's see how many times 2 fits into 378723.

Going ahead to step 1:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 2 from 3 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

On to step 2:
When dividing 17 by 2, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 16 away from 17, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Step 3:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 189.0
Subtract 18 from 18 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

On to step 4:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1893.0
If we take 6 away from 7, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 18936.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

On to step 6:
2 goes into 3 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 189361.0
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.

Moving on to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 189361.5
The remainder is 0 after subtracting 10 from 10.
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:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 189361.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 189361.5
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.

The quotient of the division is 189361.5, and the remainder is 0.0.
