The Championship table-topping Magpies had to come from behind to earn a 1-1 draw as on-loan striker Marlon Harewood's first goal for the club cancelled out Ben Watson's opener.
And Hughton feels that his team will now be aware that they will not have it all their own way as they attempt to earn an immediate return to the Premier League.
He said: "It's a big reminder for anybody of the quality in this league, the amount of games you need to play, and you are up against Championship-hardened teams who are used to playing the amount of games we are going to play.
Fair result"It's a big reminder, and it's something we keep stressing to the players.
"If I look at the games we have played so far this season, we have had to fight hard for everything we have got."
Rangers boss Magilton said: "A draw is probably a fair result. I am very proud of the players. To a man, they were outstanding.
"I still think it's going to be a division where - we have seen results already this year - it's still going to be a pretty open division.
"But if you look at the talent and the ability and the squad-depth of Newcastle, if you finish above them, you will be very close."
