Three - all nonzero digits are significant.
Three of them.
The possible remainders are {0, 1, 2, 3, 4, 5, 6, 7} making eight of them.
There are 8 possible remainders; they are: 0 (or no remainder), 1, 2, 3, 4, 5, 6 and 7.
10.
Only 3 non-zero remainders.1, 2, and 3 are the only possible non-zero remainders since any number greater than or equal to the divisor could also be divided, to result in a new quotient. A remainder of zero, means that the dividend is divisible by the divisor (the divisor is a factor of the number)
The possible number of remainders is always one less than the divisor.
When 9 is used as a divisor, the remainders can range from 0 to 8. This is because the remainder is always less than the divisor. So, if you divide any number by 9, the possible remainders can be 0, 1, 2, 3, 4, 5, 6, 7, or 8.
In division by 5, you can have remainders of 0, 1, 2, 3, and 4. If you count zero, then you can have five possible remainders. If you are not counting zero, then 4 possible remainders.

Oh, honey, when your divisor is 9, you can have 9 possible remainders ranging from 0 to 8. It's like trying to pick the best cheesecake flavor at a dessert buffet - plenty of options, but only one will satisfy your math cravings. So, buckle up and start dividing, because there's no shortage of remainders when 9 is in town.

A nonzero multiple of a number is a multiple which is not equal to 0.
Three - all nonzero numbers are significant.
