For date part in cell B2 place this array formula. Since this is an array formula so you need to confirm it with Ctrl+Shift+Enter instead of just Enter. (i.e. hold down Ctrl+Shift and then press Enter)
=LEFT(A2,MIN(IF(ISERROR(SEARCH(CHAR(ROW(INDIRECT("65:90"))),A2)),"",SEARCH(CHAR(ROW(INDIRECT("65:90"))),A2)))-1)
For remainder part in cell C2 place this array formula. Since this is an array formula so you need to confirm it with Ctrl+Shift+Enter instead of just Enter. (i.e. hold down Ctrl+Shift and then press Enter)
=MID(A2,MIN(IF(ISERROR(SEARCH(CHAR(ROW(INDIRECT("65:90"))),A2)),"",SEARCH(CHAR(ROW(INDIRECT("65:90"))),A2))),LEN(A2)-MIN(IF(ISERROR(SEARCH(CHAR(ROW(INDIRECT("65:90"))),A2)),"",SEARCH(CHAR(ROW(INDIRECT("65:90"))),A2)))+1)
