899921 divided by 2 
We want to figure out the number of times 899921 can be divided by 2.

On to step 1:
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: 4.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Advancing to step 2:
If we divide 9 by 2, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 8 from 9, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Step 3:
2 goes into 19 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 449.0
Deduct 18 from 19 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Advancing to step 4:
19 divided by 2 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4499.0
Subtract 18 from 19 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Going ahead to step 5:
2 can be fit into 12 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 44996.0
If we subtract 12 from 12, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Advancing to step 6:
1 divided by 2 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 449960.0
Subtract 0 from 1 to 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.

Step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 449960.5
If we take 10 away from 10, 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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 449960.5
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.

Let's proceed to step 9:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 449960.5
Deduct 0 from 0 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.

In conclusion, the division gives 449960.5 with a balance of 0.0.
