905889 ÷ 2 
Let's see how many times 2 fits into 905889.

Going ahead to step 1:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 8 away from 9, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

On to step 2:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 45.0
If we take 10 away from 10, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Moving on to step 3:
When dividing 5 by 2, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
If we take 4 away from 5, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Advancing to step 4:
If we divide 18 by 2, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 4529.0
Subtracting 18 from 18 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

On to step 5:
If we divide 8 by 2, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 45294.0
Subtract 8 from 8 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Moving on to step 6:
If we divide 9 by 2, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 452944.0
If we take 8 away from 9, we end up 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.

Moving on to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 452944.5
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.

Advancing to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 452944.5
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.

Advancing to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 452944.5
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 result is 452944.5 with a remainder of 0.0.
