SQL Server - Decimal values not precisely calculated

Question

For the below calculation, the expected result is -0.0000671. But the result of the code is -0.00006800000.

declare 
    @V_A        decimal (38,11) = 99.99329,
    @V_B        decimal (38,11) = 100,
    @V_RESULT   decimal (38,11);

    print '@V_A = '+cast(@V_A as varchar) --Printed as "99.99329000000"
    print '@V_B = '+cast(@V_B as varchar) --Printed as "100.00000000000"
    SET @V_RESULT = (@V_A / @V_B) - 1;
    print '@V_RESULT = '+cast(@V_RESULT as varchar) --Printed as "-0.00006800000"

Interestingly, the below code returns exact result as expected.

select (99.99329 / 100) - 1  --Returns "-0.000067100".

Could you please help me to get the same output in the above T-SQL code? I don't want to use float as it will increase decimal places. Thanks in advance.

Environment: Azure SQL DB, DTU based.

Casting to float during calculation resolves the issue.

    @V_A        decimal (38,11) = 99.99329,
    @V_B        decimal (38,11) = 100,
    @V_RESULT   decimal (38,11);

    print '@V_A = '+cast(@V_A as varchar)  --Printed as "99.99329000000"
    print '@V_B = '+cast(@V_B as varchar)  --Printed as 100.00000000000
    SET @V_RESULT = (cast(@V_A as float) / cast(@V_B as float)) - 1;  --Printed as -0.00006710000
    print '@V_RESULT = '+cast(@V_RESULT as varchar)
