Palindromic quotients through pandigital divisions
(zerofree pandigital or ninedigital variation appended)

A pandigital number is a number containing all ten digits from 0 to 9.
For the sake of this puzzle multiplicity of the digits is not permitted.
Let us collect all those pandigital numerators which can be divided
by 2, 3, 4, 5, 6, 7, 8 or 9 so that the quotient is a palindrome.
Here is already one example given in the following source.

Who is willing to sift through all the combinations (26127360 ?)
and provide me with all the interesting statistics ?
My source says that there are 626 solutions for the divided by 9 case.
I cannot escape the palindromes, can I !

Jean Claude Rosa (email) did exactly as was asked
and is doing a good thing by giving us his data.

Terry Trotter (email) and Jean Claude Rosa (email)
reported some errors in the statistics above.

For divisor 6 there are 82 solutions instead of 81.

For divisor 7 the largest solution is : 6897405123/7 = 985343589
instead of 6895074123/7=985010589.

Terry Trotter's math-enthusiasm inspired him to create
an 'Activity' page Pandigital Diversions
with some beautiful and curious surprises as well !.

Patrick De Geest likes to add the ninedigits variation
(zerofree pandigitals) to this WONplate as well.
Here are his results : 67 solutions in total.
