We're dividing 908389 by 2 
Let's see how many times 2 fits into 908389.

Advancing to step 1:
2 goes into 9 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Advancing to step 2:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 10 away from 10, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Let's proceed to step 3:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 454.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Let's proceed to step 4:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 4541.0
Deduct 2 from 3 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Moving on to step 5:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 45419.0
Deduct 18 from 18 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Advancing to step 6:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 454194.0
Subtract 8 from 9 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.

Moving on to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 454194.5
Subtracting 10 from 10 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.

On to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 454194.5
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.

Moving on to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 454194.5
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 outcome is 454194.5, with a leftover of 0.0.
