My stepper motor have 4 wire is VEXTA motor 2 phase 1.8"/Step, DC 1.96V, 2.8A.
when i measure the resistance wire 1 & 2 is 0.8 ohms, 3 & 4 is 0.9ohms.
Is it the correct way to measure the resistance?

well not half watt resistors .... 0.75 amps though a 12.4 ohm resistor P=IIR = 0.75*0.75*12.4 = 7 watts - half watt resistors are going to smoke - maybe some 10 watt wirewounds?
One way to increase the resolution so that you can make steps close to an exact one degree is to use a microstepping driver.
That kind of driver works by PWM-modulating the current to the motor coils in a ratio that allows the rotor to stabilize in a position between the poles. You can't really increase the resolution by a huge factor, despite the driver stepping in (say) 128 or 256 microsteps but it might be good enough for you.
If you had 8 microsteps on a 1.8 angular degree motor, then each step would represent 0.225 degrees, and every 40 microsteps (9°) you'd be back to an exact full step.
You can make your own, or there are commercial suppliers such as Gecko.

Yes, that means 1 & 2 is your X0 & X1; 3 & 4 is your Y0 & Y1.
