Return All Row Numbers That Have Given Value Written Somewhere Inside Text In Column B

By "Return all row numbers that have a given value written somewhere inside text in their column B" I mean....

I want to be able to search an alphanumeric value "ABC12345" within a column that has a paragraph of text written in each row, I want to know which rows have this value written somewhere in them and have it return 2,4,33, as row 2 and 4 and 33 have this value in them inside column B on that row.

on column A i have the respective row numbers all the way down ie: ( 1,2,3,4, etc) (to pull up the row numbers)(unless you have a better way)

On Column B i have the paragraphs of text to search in (there is lots of text and spaces in the paragraphs.)

On column C i have the value to look for... ie: ABC12345 (different values in each row of column C) to be compared to all of column B

On column D would be the formula to Pull down and get the results.

and something tells me you might have a better way of getting the row numbers rather than having column A dedicated to numerating each row 1,2,3,etc
