We divide 90436 by 2
We want to divide 90436 by 2.

Let's proceed to step 1:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our 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

Going ahead to step 2:
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: 45.0
Deduct 10 from 10 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Going ahead to step 3:
2 goes into 4 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 452.0
If we subtract 4 from 4, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Going ahead to step 4:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4521.0
Subtract 2 from 3 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Let's proceed to step 5:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 45218.0
If we take 16 away from 16, 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.

Moving on to step 6:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45218.0
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.

Step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45218.0
If we take 0 away from 0, 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.

After the division, we end up with 45218.0 and a remainder of 0.0.
