We look at the division of 170993 by 2 
Our goal is to divide 170993 by 2.

On to step 1:
When dividing 1 by 2, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Advancing to step 2:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 16 away from 17, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Moving on to step 3:
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: 85.0
If we subtract 10 from 10, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Advancing to step 4:
When dividing 9 by 2, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 854.0
Subtract 8 from 9 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

On to step 5:
If we divide 19 by 2, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 8549.0
Subtract 18 from 19 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Let's proceed to step 6:
13 divided by 2 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 85496.0
Subtracting 12 from 13 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.

Advancing to step 7:
2 goes into 10 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 85496.5
Subtracting 10 from 10 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:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 85496.5
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.

Step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 85496.5
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.

In conclusion, the division gives 85496.5 with a balance of 0.0.
