If you use an Integer, you cannot expect 3.3333333 or something like that.
Try to use a "REAL":


var
  a,b,c: real;
begin
  a := 10;
  b := 3;
  c := a / b;
end;

Here, b will get 3.33333 as its value.

Good luck!

You can use the Val procedure or Format function to convert from real to string.

Declare the variables this way:

var
  f :real;
  x, y, q ,z :integer;


and perform the computation this way:

f := q / z;
x := round(x * f);
y := round(y * f);

"round" is a function that accepts an expression of type "real", and returns the result (as an integer) rounded to the nearest whole number
