Measure current on a constant current source
With 156 mA through 19.01 Ohms (load + shunt), the maximum voltage will be 2.966 Volts, which should not be a problem for typical 3.3 Volt microcontrollers. 

Therefore the voltage dividers may be unnecessary for reading the voltage at either side of that shunt. 

Further, the Voltage developed across the 10 milliOhm shunt will be a mere 1.56 milliVolts. At approximately 3.22 mV per consecutive ADC reading on the MCU (3.3 Volts full-scale / 1024, assuming 10 bit Atmel MCU ADC) there will not be much to be read between the high and low side of that shunt. 

Adding the voltage divider does nothing useful as far as I can see, and it definitely will reduce the voltage to the ADC, challenging it to read anything useful.
