99690 ÷ 2 
Let's see how many times 2 fits into 99690.

Going ahead to step 1:
2 goes into 9 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 8 from 9 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Let's proceed to step 2:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtracting 18 from 19 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Going ahead to step 3:
16 divided by 2 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 498.0
The remainder is 0 after subtracting 16 from 16.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Moving on to step 4:
9 divided by 2 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4984.0
Subtract 8 from 9 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Let's proceed to step 5:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 49845.0
Subtract 10 from 10 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.

On to step 6:
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: 49845.0
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 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49845.0
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 result is 49845.0 with a remainder of 0.0.
