NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V1400 will be loaded into the accumulator
using the Load instruction. The value in V1420 and V1421 is loaded into the accumulator
using the Load Double instruction also, pushing the value previously loaded in the accumulator
onto the accumulator stack. The binary value in the accumulator is divided by the binary value
in the first level of the accumulator stack using the Divide Binary Stack instruction. The value
in the accumulator is copied to V1500 and V1501 using the Out Double instruction.

Discrete Bit Flags Description
SP53 On when the value of the operand is larger than the accumulator can work with.
SP63 On when the result of the instruction causes the value in the accumulator to be zero.
SP70 On any time the value in the accumulator is negative.

Divide Binary by Top OF Stack (DIVBS)
Divide Binary Top of Stack is a 32-bit instruction that divides
the 32-bit binary value in the accumulator by the 16-bit binary
value in the first level of the accumulator stack. The result resides
in the accumulator and the remainder resides in the first level of
the accumulator stack.
