Your question indicates: Total cost in wei units = 67123160000000000 Gas price in wei units = 20000000000 This implies that the amount of gas required is 67123160000000000 / 20000000000 = 3356158. This amount of gas should be identical on every network (assuming that you're using the same compiler in order to generate the byte-code which you are deploying)...

Everything (no exceptions) starts with a transaction signed by an externally owned account (EOA). Signed transactions are sent to the network and included in a block. Blocks establish the canonical transaction order. (Peer discovery, gossip and mining.) Ordered transactions are processed by nodes as the blocks arrive. To deploy that contract, first, it is ...
