The figure was revealed as Mr Paisley's suspension was yesterday lifted by the DUP and he was readmitted to the party.
The decision was announced just hours after he survived the attempt to oust him from the seat his father once held - by just 0.4% of the vote.
Sinn Fein vice-president Michelle O'Neill denounced the DUP decision and said the party leadership was effectively endorsing his actions.
It came as the PSNI said it was investigating comments on social media linked to the recall petition. Mr Paisley confirmed he has made three complaints to police over allegations electoral law was broken over the process.
The MP yesterday said he was "humbled and privileged" by the electorate's decision and praised his family and "true friends" for standing by him.
"I was asked to make an apology, I gave that apology, and I believe that 90.6% of the electorate who had the opportunity to say 'we don't accept that apology', I believe they said 'we do accept that apology, and we are prepared to move on'," he said.
"I must say I am delighted with that, delighted with the unwavering support I have received from my constituents. Hopefully now we can move on and get on with the real job I am elected to do."
Mr Paisley said his political opponents had failed, adding: "My detractors had every opportunity to achieve a very low threshold of 10% of the electorate, they had every opportunity to gang together from across parties, which they did, and they couldn't muster 10% of the electorate to sign that petition.
"This was the easiest process to be involved in, you could have done this from your living room, you didn't have to go out to a polling station.
"Of course there will be a menu of reasons for why they took that view but I think people thought we are going to stick with the MP we have. I do take that as an endorsement but I don't take it as a 'congratulations, well done'."
He continued: "I will go back to Westminster on the second week of November and all of the crucial votes post-Brexit will be after that anyway, so I do miss the 30 sitting days and I lose my salary for that, which is my financial punishment and I have to accept that.
"I will continue to do the job I have been elected to do and I hope the people will respect me for doing that."
Mr Paisley also revealed he had contacted the PSNI over alleged breaches of the electoral law.
There are strict rules over what can be said or published during the six weeks the petition is open which, if broken, can carry potential fines and prison terms.
The Electoral Office contacted Sinn Fein North Antrim MLA Philip McGuigan over a video he posted to social media earlier this week. Mr McGuigan denies any wrong-doing.
Mr Paisley said: "A number of people have breached section 124 of the election law and I have raised at least three specific complaints about individuals with police.
"It's up to police now to take that forward. I know if I had breached the law in that way, the same people would be asking questions."
A PSNI spokesman said: "Police have received a report in relation to comments made on social media. Enquiries are ongoing."
Mr Paisley was suspended from Westminster for failing to declare two luxury holidays paid for by the Sri Lankan government.
The DUP announced that Mr Paisley had been readmitted to the party on Tuesday but would be barred from holding office within the party for a year.
"The internal processes surrounding these matters have been completed," a party spokesman said.
"On Tuesday, September 18 Mr Paisley was readmitted to membership of the party following a suspension of 57 days and upon readmission he is subject to a number of conditions including a ban on holding office within the party for 12 months.
"The party will be making no further comment on these matters."
