Considering that you only have 'A', 'T', 'G', and 'C', it's certainly not impossible that there are various ways how $A can be contained in $B. Is it a given that $A has to be split into four pieces? Can there be more ways? If there are multiple ways of splitting $A which way should be choosen? There are two contraints I would find logical: the one that minizes the number of parts $A splits in, and the one that maximizes the length of the smallest part.
