My understanding of your question is that you want to change the default answer received when we use division operator. You cannot alter the default operation but there are some other methods which you can use -
1.Use fixed-point numeric objects and settings.
F = fimath('RoundingMethod', 'floor');
A = fi([7], 1, 32, 0, F);
B = fi([4], 1, 32, 0);
ans = A/B;

2. Use other datatypes like single/double.
floor(single(7)/single(4))
Or
floor(7/4) % By default, MATLAB stores all numeric variables as double-precision floating-point values
3. Use idivide function.
idivide(int32(7), int32(4))
