245489 ÷ 2 
We want to figure out the number of times 245489 can be divided by 2.

Going ahead to step 1:
2 divided by 2 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Going ahead to step 2:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 4 from 4 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Moving on to step 3:
2 goes into 5 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 4 from 5 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Going ahead to step 4:
The number 2 fits into 14 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 1227.0
Subtracting 14 from 14 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Going ahead to step 5:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 12274.0
If we subtract 8 from 8, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Step 6:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 122744.0
The remainder is 1 after subtracting 8 from 9.
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:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 122744.5
If we subtract 10 from 10, 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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 122744.5
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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 122744.5
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 122744.5 with a remainder of 0.0.
