Electronic – assume that groundings in electrical circuits can be split

Assume there's a circuit like this:

What I'm asking is if I can split the grounding points like this:

The reason I want to do it is just for simplicity sake. I don't have an excellent physics background, but the grounding points like these always confuse me when doing calculations. I know that the voltages on all three of these points is equal, although this kind of circuit may create some problems in real life scenarios, I believe it's just easier to read. Will this produce wrong answers for calculating currents and voltages?

Schematic-wise both drawings are equal and analysing them makes no difference. It just assumes wires are ideal.

In real life, you can implement how the currents return to battery in many ways, as real life wires have resistance and thus currents flowing in wires create voltage difference, but that can be ignored if your circuit is not a precision circuit.
