I've watched enough divisions
Divisions in the House of Commons (parliament.uk)
Standing Orders Nos. 38-41 direct how divisions are administered. When a motion is put to the vote, the Speaker ‘puts the question’, by saying: The Question is, that ... [for example, the Bill be read a second time]. As many as are of that opinion say Aye", (there then follows a chorus of shouted Ayes), "of the contrary No" (a similar shout of No) ...
At this point, if there is no dissent, the motion will be carried, and the Speaker will say “I think the Ayes have it”.1 He will then confirm that the Ayes have it. There is then no need for a formal division to take place. However, if Members do not agree, the Speaker calls a division. He/she announces, "Clear the Lobbies". The division bells ring throughout the House of Commons estate, the Annunciators display "Division", and the police direct all non-Members to leave the vicinity of the Members' Lobby.
The police also walk through the public rooms of the House shouting "Division". (See below for explanations of the division bells and annunciators.) The Speaker has the discretion to ask each side to stand in their places in the Chamber, if s/he believes that a division is unnecessary.
2 Two minutes after the Speaker ‘puts the question’, s/he does the same thing a second time. If the outcome is unchallenged or one side cannot find two tellers then the division is called off. The Annunciators display ‘Division off’, and the Speaker announces, "The Ayes (or Noes) have it".3 If Members indicate that a division is still required, the Speaker then says, "Tellers for the Ayes, Ms A and Mr B, tellers for the Noes, Mr C and Ms D".
I wonder if they could find 2 tellers as well?
