Just set __ as FS value. You could also pass a regex as FS value.

$ echo '1__2_3__4_5_6' | awk -v FS="__" '{print $1}'
1
$ echo '1__2_3__4_5_6' | awk -v FS="__" '{print $2}'
2_3
$ echo '1__2_3__4_5_6' | awk -v FS="__" '{print $3}'
4_5_6
$ echo '1__2_3__4_5_6' | awk -v FS="_{2}" '{print $3}'
4_5_6

_{2} matches exactly two underscores.
