@halo572I don't know how it works, but when the game cannot do the math, they use if statements and replace zero by 1.
If K = x and D = 0, then D = 1.
Therefore 1/0 is replaced by 1/1, the result is 1, which is 100% success.
In theory, the lower the number you divide something by, the higher the result.
10/10 = 1
10/5 = 2
10/1 = 10
10/0.1 = 100
Then the closer to zero, the closer you would get to infinity. Computers can't handle these numbers
Although a K/D of 1 would be unfair for someone who does 10/0, the game cannot attribute a random value, so I believe the game would replace it to 10/1 which is the closest value, and even though, it is not the real number.
