We divide 909958 by 2
Let's see how many times 2 fits into 909958.

On to step 1:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 8 from 9, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Moving on to step 2:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 10 from 10 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Moving on to step 3:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 454.0
Subtracting 8 from 9 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

On to step 4:
If we divide 19 by 2, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4549.0
If we take 18 away from 19, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Step 5:
When dividing 15 by 2, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 45497.0
If we subtract 14 from 15, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Moving on to step 6:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 454979.0
If we take 18 away from 18, 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.

On to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 454979.0
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.

Let's proceed to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 454979.0
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.

The final outcome is 454979.0, with a leftover of 0.0.
