We're dividing 173199 by 2 
We want to figure out the number of times 173199 can be divided by 2.

Advancing to step 1:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

On to step 2:
When dividing 17 by 2, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 1 after subtracting 16 from 17.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Let's proceed to step 3:
13 divided by 2 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 12 from 13 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Going ahead to step 4:
The number 2 fits into 11 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 865.0
Subtract 10 from 11 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Moving on to step 5:
If we divide 19 by 2, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8659.0
Subtract 18 from 19 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Advancing to step 6:
2 goes into 19 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 86599.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 86599.5
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:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 86599.5
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.

On to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 86599.5
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 result is 86599.5 with a remainder of 0.0.
