Cursor issue

I have Invoices table and a Quotes table, each record in the quotes table has a fixed amount quote, I have a cursor that updates each quote depending of the total of the invoice amount, and if one quotes has to be splitted in order for it to, grouped with the other ones, sums the total of the invoice amount, it has to be done, the process works fine but it takes a long time in the execution.
Here is the code:
DECLARE TCUR CURSOR FOR
SELECT IDCUOTA, CUOTA
FROM CUOTAST WHERE IDSTATUS=1 AND IDBIDS=@IDBIDS AND IDFRANJA=@IDFRANJA

OPEN TCUR
FETCH NEXT FROM TCUR INTO @IDCUOTA, @CUOTAT

WHILE @@FETCH_STATUS=0 BEGIN

IF @TOTFACT<@CUOTAT BEGIN
SET @DIF=@TOTFACT

UPDATE CUOTAST SET IDFACTURA=@IDFACTURA, IDSTATUS=3 WHERE IDBIDS=@IDBIDS AND IDFACTURA IS NULL AND IDCUOTA=@IDCUOTA AND IDSTATUS=1

INSERT INTO CUOTAST
SELECT @IDCUOTA + 'A', IDUNIDAD, FECHAAFP, IDMARCA, IDBIDS, IDFRANJA, IDTIPOVEHICULO, @IDCUOTA, @DIF, IDFACTURA, 2, COMENTARIOS, IDMODIFICACION
FROM CUOTAST WHERE IDCUOTA=@IDCUOTA


INSERT INTO CUOTAST
SELECT @IDCUOTA + 'A', IDUNIDAD, FECHAAFP, IDMARCA, IDBIDS, IDFRANJA, IDTIPOVEHICULO, @IDCUOTA, @CUOTAT - @DIF, NULL, 1, COMENTARIOS, IDMODIFICACION FROM CUOTAST WHERE IDCUOTA=@IDCUOTA
BREAK
END
IF @TOTFACT> @CUOTAT BEGIN
IF @SUBT < @TOTFACT BEGIN
IF @DIF > @CUOTAT BEGIN
UPDATE CUOTAST SET IDFACTURA=@IDFACTURA, IDSTATUS=2 WHERE IDBIDS=@IDBIDS AND IDFACTURA IS NULL
AND IDCUOTA=@IDCUOTAAND IDSTATUS=1
SET @SUBT=@SUBT + @CUOTAT
SET @DIF=@TOTFACT-@SUBT
END ELSE
IF @DIF < @CUOTAT BEGIN
UPDATE CUOTAST SET IDFACTURA=@IDFACTURA, IDSTATUS=3 WHERE IDBIDS=@IDBIDS AND IDFACTURA IS NULL
AND IDCUOTA=@IDCUOTA AND IDSTATUS=1
INSERT INTO CUOTAST
SELECT @IDCUOTA + 'A', IDUNIDAD, FECHAAFP, IDMARCA, IDBIDS, IDFRANJA, IDTIPOVEHICULO, @IDCUOTA,
@DIF, IDFACTURA, 2, COMENTARIOS, IDMODIFICACION
FROM CUOTAST WHERE IDCUOTA=@IDCUOTA

INSERT INTO CUOTAST
SELECT @IDCUOTA + 'A', IDUNIDAD, FECHAAFP, IDMARCA, IDBIDS, IDFRANJA, IDTIPOVEHICULO, @IDCUOTA, @CUOTAT - @DIF, NULL, 1, COMENTARIOS, IDMODIFICACION
FROM CUOTAST WHERE IDCUOTA=@IDCUOTA
BREAK
END
END
END
FETCH NEXT FROM TCUR INTO @IDCUOTA, @CUOTAT
END
CLOSE TCUR
DEALLOCATE TCUR

Can some one show some pointers in doing without the cursor?

Try using inserting your CURSOR select into temp table and join the temp table for update and insert
OR

Try to figure it out the all condions and change your WHERE clause in your update and insert...like the following once...
UPDATE CUOTAST SET IDFACTURA=@IDFACTURA, IDSTATUS=3
WHERE IDBIDS=@IDBIDS AND IDFACTURA IS NULL
AND CUOTA> @TOTFACT AND IDSTATUS=1
AND IDFRANJA=@IDFRANJA

INSERT INTO CUOTAST
SELECT IDCUOTA + 'A', IDUNIDAD, FECHAAFP, IDMARCA, IDBIDS, IDFRANJA,
IDTIPOVEHICULO, @IDCUOTA, @TOTFACT, IDFACTURA, 2, COMENTARIOS, IDMODIFICACION
FROM CUOTAST WHERE IDFRANJA=@IDFRANJA AND CUOTA> @TOTFACT AND IDFRANJA=@IDFRANJA
