448578 ÷ 2 
We're looking to find how many times 2 goes into 448578.

Moving on to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Let's proceed to step 2:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 4 from 4, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

On to step 3:
When dividing 8 by 2, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 224.0
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

Let's proceed to step 4:
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: 2242.0
The remainder is 1 after subtracting 4 from 5.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Moving on to step 5:
If we divide 17 by 2, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 22428.0
The remainder is 1 after subtracting 16 from 17.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Let's proceed to step 6:
If we divide 18 by 2, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 224289.0
The remainder is 0 after subtracting 18 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 224289.0
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.

Let's proceed 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: 224289.0
Subtracting 0 from 0 leaves us 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 224289.0 with a remainder of 0.0.
