Yes i do!

Which language?

You must to sucessive divisions by 10 and hold the remainder of each division
in a temporary memory, until the quocient is 0.
See:

214/10 = 21 and the remainder is 4
21/10  = 2  and the remainder is 1
2/10   = 0  and the remainder is 2

                                 ^
                                 |
                                 |
                                look the remainders: are the digits for
                                display at LCD.
                                You must to add 48 (ASCII CODE OF "0") and
                                them you will have a printable caracter!

Here two samples for you! One in C and other for 8051 assembly!

           Data_Out('0');
         for(RESTO=NUMERO_DIGITO;RESTO>0;RESTO--)
            Data_Out(DIGITOS[RESTO]+0x30);     /* TABELA ASCII NUMEROS */
}                                              /* + 0x30 */

Assembly
----------

IMP_BYTE_lcd:

   PUSH ACC
   PUSH B
   PUSH H'00
   MOV H'00,#0
NAO_FIM:
   MOV B,#D'10
   DIV AB
   INC H'00
   PUSH B
   CJNE A,#0,NAO_FIM
IMP_DIGITO:
   POP B
   MOV A,B
   ADD A,#H'30
   ACALL DATA_OUT         ; WRITE THE VALUE OF A AT LCD
   DJNZ H'00,IMP_DIGITO
   POP H'00
   POP B
   POP ACC
   RET

Do you know how to initialize a display?
