We divide 86155 by 2
Let's see how many times 2 fits into 86155.

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
If we take 8 away from 8, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Step 2:
6 divided by 2 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 6 away from 6, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Let's proceed to step 3:
If we divide 1 by 2, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 430.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Advancing to step 4:
If we divide 15 by 2, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 4307.0
The remainder is 1 after subtracting 14 from 15.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 5:
2 can be fit into 15 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 43077.0
Subtracting 14 from 15 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 6:
2 goes into 10 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 43077.5
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.

Moving on to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43077.5
If we subtract 0 from 0, 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.

Moving on to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43077.5
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 43077.5 and a remainder of 0.0.
