when current passes through the shunt resistance then how galvanometer measures the whole current? i mean the current is divided in two paths and some of it passes through the shunt then how galvanometer measures current accurately?

A shunt resistor is provided to allow only a *known fraction* of the total current to flow through the actual galvanometer. Technically you're not measuring the total current...you're measuring the fractional current and scaling it up appropriately (based on the shunt resistance vs coil resistance ratio).
can you explain what do you mean by" scaling it up appropriately(based on shunt resistance vs coil resistance ratio)??
