But the bill's passage through the House of Lords in the coming weeks could be far harder because the upper chamber is dominated by the pro-EU opposition.
Heralding the moment, Brexit Secretary David Davis said: "From the beginning our approach has been to work constructively with MPs from across the House wherever possible to improve the Bill".
He added: "This is a critical piece of legislation that aims to maximise certainty for individuals and businesses after our exit".

Announcing Labour's opposition to the bill at third reading, shadow Brexit secretary Sir Keir Starmer branded it "not fit for purpose" as he repeated demands for MPs to have a meaningful vote on any divorce deal with the EU.
The Scottish and Welsh governments are also concerned that the bill will allow the Conservative government to seize control over policy areas that they believe ought to be devolved to Holyrood and Cardiff.
However, while Tory rebel Remainers may have sat on their hands tonight, it's clear that the battle is far from over for May in passing this bill. Many lords are opposed to Brexit.
"Ministers will have extraordinary powers to make laws under this Bill, so it is vital that each of the UK's legislatures have the opportunity to scrutinise effectively regulations made under these highly unusual ministerial powers".
