How to check how much percentage index operation has been done

DECLARE @Processid INT = 70 ---here mention SPid (session id)

;WITH Summary AS

(     SELECT SUM(qp.[row_count]) AS [RowsProcessed],

             SUM(qp.[estimate_row_count]) AS [TotalRows],

             MAX(qp.last_active_time) - MIN(qp.first_active_time) AS [ElapsedMS],

             MAX(IIF(qp.[close_time] = 0 AND qp.[first_row_time] > 0,

[physical_operator_name],

N'<Transition>')) AS [CurrentStep]

FROM sys.dm_exec_query_profiles qp

WHERE qp.[physical_operator_name] IN (N'Table Scan', N'Clustered Index Scan', N'Index Scan',  N'Sort')

AND   qp.[session_id] = @Processid

), Result AS

(

     SELECT *,

            ([TotalRows] - [RowsProcessed]) AS [RowsLeft],

            ([ElapsedMS] / 1000.0) AS [ElapsedSeconds]

     FROM   Summary

)

SELECT [CurrentStep],

       [TotalRows],

       [RowsProcessed],

       [RowsLeft],

       GETDATE() AS [CurrentTime],

       CONVERT(DECIMAL(5, 2),

      (([RowsProcessed] * 1.0) / [TotalRows]) * 100) AS [PercentComplete]

FROM   Result;

output

CurrentStep TotalRows RowsProcessed RowsLeft CurrentTime PercentComplete
