We divide 845223 by 2
We're looking to find how many times 2 goes into 845223.

Moving on to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Step 2:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Let's proceed to step 3:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 422.0
If we subtract 4 from 5, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Moving on to step 4:
The number 2 fits into 12 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 4226.0
If we take 12 away from 12, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

On to step 5:
2 divided by 2 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 42261.0
If we take 2 away from 2, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Moving on to step 6:
3 divided by 2 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 422611.0
If we subtract 2 from 3, we get 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:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 422611.5
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.

Advancing to step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 422611.5
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 422611.5
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.

The final result is 422611.5 with a remainder of 0.0.
