List Trouble

Hi folks

I have a really weird problem on my hands. Im trying to do a very very basic division, which keeps going wrong and I was hoping someone could tell me where I've missed something.

Here's what I am trying to:

I'm creating a card game, and am trying to write a script to reposition the cards in a person's hand when they draw a new one. Because theoretically the player can have as many cards as they want in their hand, and those cards need to be readable, I have decided that every time a card gets added to the hand they should bunch together a little tighter, and then when the player mouses over a card, that card comes to the front. Currently though, the problem is strictly to do with the cards getting more closely bunched together.

To do this I have got two empty gameObjects to act as transform markers for the furthest points on either end of the hand a card could go. Then I have written a script to work out where each card should go between those two points. (for now ignore cards being on top of one another and just focus on their side-to-sideness). I have a list that contains each of my cards objects.

In the Debug Lines below it gets lines 15, 16 & 17 correct, but then lines 18 & 19 always goes funny. With 3 cards in the list, it usually creates a result of 0% for cards0&1, and then gives a value of 1(100%) for card2.

Any help with this basic division would be much appreciated. Thankyou.

 public List<GameObject> HandCards;        // holds instantiated card gameobjects
 public Transform farLeftPoint;            // the hand is resized dynamically as cards are added to the hand. This is the furthest left a card can be.
 public Transform farRightPoint;            // the hand is resized dynamically as cards are added to the hand. This is the furthest right a card can be.
 public float spaceBetweenCards = 0.1f;        // the amount of space thickness between each card
 
 private int handSize;                        // how many cards are in the players hand?
 
 void ResizeHand(int listNumber)
 {
         for (int t = 0; t < handSize; t++)
         {
             int temp = Mathf.Abs (listNumber + t); //calculate number of cards this card is from the focus card
 
             float percent = (t+1) / handSize; //how far along in a 0-1 should this card be between the farLeft&farRight points
             Debug.Log (t);
             Debug.Log (t + 1);
             Debug.Log (handSize);
             Debug.Log ((t + 1)/handSize);
             Debug.Log ("Card Number " + t + " is " + (percent * 100) + "% along the line.");
 
             HandCards[t].transform.position = new Vector3(Mathf.Lerp(farLeftPoint.position.x, farRightPoint.position.x, percent), farLeftPoint.position.y - (temp * spaceBetweenCards), farLeftPoint.position.z);
         }
 }
