485321 ÷ 2 
We want to figure out the number of times 485321 can be divided by 2.

Advancing to step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Let's proceed to step 2:
2 goes into 8 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Advancing to step 3:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 242.0
If we subtract 4 from 5, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

Step 4:
If we divide 13 by 2, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 2426.0
The remainder is 1 after subtracting 12 from 13.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Let's proceed to step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 24266.0
Subtract 12 from 12 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Let's proceed to step 6:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 242660.0
Deduct 0 from 1 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.

On to step 7:
10 divided by 2 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 242660.5
Deduct 10 from 10 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.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 242660.5
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.

Going ahead to step 9:
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: 242660.5
If we subtract 0 from 0, 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.

The final outcome is 242660.5, with a leftover of 0.0.
