Getting two counts and then dividing them

Question

I am attempting to get two counts and then divide those two counts to get the ratio of the items I am counting. I saw this post here and tried that. I am getting an error in my results, no error message just incorrect number. I am using SQL-Server 2008

Here is my code:

-- INTERNAL PEPPER REPORT
--#####################################################################

-- VARIABLE DECLARATION AND INITIALIZATION
DECLARE @SD DATETIME
DECLARE @ED DATETIME

SET @SD = '2013-01-01'
SET @ED = '2013-03-31'

-- TABLE DECLARATION ##################################################
DECLARE @TABLE1 TABLE(NUMERATOR INT, DENOMINATOR INT, RATIO INT)
--#####################################################################

-- WHAT GETS INSERTED INTO TABLE 1
INSERT INTO @TABLE1
SELECT
A.NUM, A.DENOM, A.NUM/A.DENOM 

FROM
(
-- COLUMN SELECTION. TWO NUMBERS WILL REPRESENT A NUM AND A DENOM
SELECT 
    (SELECT COUNT(DRG_NO)
        FROM smsdss.BMH_PLM_PtAcct_V
        WHERE drg_no IN (061,062,063,064,065,066)
        AND Adm_Date BETWEEN @SD AND @ED
        AND PLM_PT_ACCT_TYPE = 'I')
        AS NUM,
    (SELECT COUNT(DRG_NO)
        FROM smsdss.BMH_PLM_PtAcct_V
        WHERE drg_no IN (061,062,063,064,065,066,067,068,069)
        AND Adm_Date BETWEEN @SD AND @ED
        AND Plm_Pt_Acct_Type = 'I')
        AS DENOM
)A

SELECT NUMERATOR, DENOMINATOR, RATIO
FROM @TABLE1

The counts get produced and displayed correctly, but for a ratio I get 0 and am not sure as to why I get this.

Thank You,

Use SELECT A.NUM, A.DENOM, cast(A.NUM as float)/cast(A.DENOM as float)

SQL Server consider that A.NUM / A.DENOM are int, because A.NUM and A.DENUM are int
