We're dividing 999621 by 2 
Let's see how many times 2 fits into 999621.

Going ahead to step 1:
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: 4.0
If we take 8 away from 9, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Let's proceed to step 2:
When dividing 19 by 2, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 18 from 19 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Going ahead to step 3:
2 can be fit into 19 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 499.0
Subtracting 18 from 19 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Step 4:
When dividing 16 by 2, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 4998.0
If we subtract 16 from 16, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Step 5:
2 divided by 2 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 49981.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Advancing to step 6:
If we divide 1 by 2, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 499810.0
Subtracting 0 from 1 leaves us 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.

On to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 499810.5
If we take 10 away from 10, 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.

Step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 499810.5
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.

Let's proceed to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 499810.5
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.

After the division, we end up with 499810.5 and a remainder of 0.0.
