( n1 n2 -- n3 )

Divide n1 by n2, giving the single-cell quotient n3. An ambiguous condition exists if n2 is zero. If n1 and n2 differ in sign, the implementation-defined result returned will be the same as that returned by either the phrase >R S>D R> FM/MOD SWAP DROP or the phrase >R S>D R> SM/REM SWAP DROP.

See:
3.2.2.1 Integer division.

Testing:
IFFLOORED    : T/ T/MOD SWAP DROP ;
IFSYM        : T/ T/MOD SWAP DROP ;
