The particle to should not be separated from the following infinitive:
Examples: I told him to stop fooling around
We began to unwrap the Christmas tree
but not: "She began to slowly get off the floor."
There are, however, instances when a split infinitive must be accepted as in the following example:
Your job is to really make things work.
Without the split infinitive the sentence has another meaning:
Your job is really to make things work
("really" = the real purpose of your job)
