We're dividing 86917 by 2 
Our goal is to divide 86917 by 2.

Advancing to step 1:
8 divided by 2 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Let's proceed to step 2:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Moving on to step 3:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 434.0
Subtracting 8 from 9 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Let's proceed to step 4:
When dividing 11 by 2, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 4345.0
Subtracting 10 from 11 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Let's proceed to step 5:
When dividing 17 by 2, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 43458.0
Subtracting 16 from 17 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.

Moving on to step 6:
10 divided by 2 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 43458.5
If we subtract 10 from 10, we 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.

Going ahead to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43458.5
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.

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: 43458.5
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.

The final outcome is 43458.5, with a leftover of 0.0.
