About Wildcards> How to subscript the digits only of a string such as N12 or D3

Hi

I have a text like this.

(N5-N56)/D50
= 5,658848 (N56-N60)/D50
= 3,307378 (N60-N63)/D50
= 2,225554 (N63-N65)/D50
= 1,358529 (N65-N76)/D50
= 5,533397
39.767,60 28.645,20 19.275,52 11.766,22 67.094,65

I want to select all text and subscript any digit of 1 or 2 characters (these are ages) that's followed by D or N by a single click using wildcards.

My code above makes the D and N characters to subscript as well. (So I need a second correction to make them big again).
\2 to the second box removes D and N terms. I have to keep them unchanged.

I just obsessed with this but couldn't find a way.

Sorry, I couldn't express myself clearly.
This is a word question about using wildcards for find/replace though I copy and paste the data from excel. I just wondered if there is a single line code for that.
Find: ([DN])([0-9]{2})
Replace: \1\2 subscript format

I need to tell something into replace box for \1 term to remain unchanged.

Oh I see, thank you for the information
