Well, think about it as if the characters were boxes lined up. If you want to put a box somewhere in the middle, you need to make room somehow. Usually the two methods of making room are swapping an existing box with the new box, and shoving boxes out of the way.
Since order matters, shoving boxes works better:
Given a row of boxes
[c][a][f][e]
Find where you want to place new boxes
[c][a]|[f][e]
Shove boxes out of the way to make room
[c][a] [f][e]
Set the new box(s) down
[c][a][x][z][f][e]This process is easily translated to an algorithm.
