  Divisor - Wikipedia, the free encyclopedia
Numbers divisible by 2 are called even and those that are not are called odd.
The name comes from the arithmetic operation of division: if a/b = c then a is the dividend, b the divisor, and c the quotient.
This lattice is isomorphic to the dual of the lattice of subgroups of the infinite cyclic group Z.

 Divisible group - Wikipedia, the free encyclopedia
In group theory, a divisible group is an abelian group G such that for any positive integer n and any g in G, there exists y in G such that ny = g.
One can show that G is divisible if and only if G is an injective object in the category of abelian groups.
Since a divisible group is an injective module, Tor(G) is a direct summand of G.

Moreover, it is plain that everything continuous is divisible into divisibles that are infinitely divisible: for if it were divisible into indivisibles, we should have an indivisible in contact with an indivisible, since the extremities of things that are continuous with one another are one and are in contact.
The same reasoning will show the divisibility of the length, and in fact of everything that forms a sphere of change (though some of these are only accidentally divisible because that which changes is so): for the division of one term will involve the division of all.
And we now see that in most cases the fact that all the terms are divisible or infinite is a direct consequence of the fact that the thing that changes is divisible or infinite: for the attributes 'divisible' and 'infinite' belong in the first instance to the thing that changes.

One interesting way of passing time is to try and figure out whether some large number is divisible by some smaller number (which is another way of saying that the large number is congruent to 0 modulo the smaller number).
For example, 284,691 is divisible by 3 because its digits sum to 2+8+4+6+9+1 = 30, and 30 is a multiple of 3.

 Division by 81
For those who remember the rules that a number is divisible by 3 and 9 if and only if (iff) the sum of its digits is divisible by 3 or 9, respectively, it's tempting to assume that the same applies to 81.
That is a number is divisible by 81 iff the sum of its digits is divisible by 81.
Therefore the number in parenthesis is divided by 9 and hence N is divisible by 81.

So, to continue the last example, 33333888 is divisible by 8 because the digit in the hundreds place is an even number, and the last two digits are 88, which is divisible by 8.
33333886 is not divisible by 8 because the digit in the hundreds place is an even number, but the last two digits are 86, which is not divisible by 8.
First we want to find whether it is divisible by 11, but on the way we are going to save the numbers that we use: in every step we will subtract the last digit from the other digits, then save the subtracted amount in order.

This new type of property is called "divisible property." To understand why the legislature thought it necessary to add a new type of property, it is important to understand that the date for valuation of marital property in North Carolina is a couple's date of separation.
All appreciation and diminution in value of marital property and divisible property of a couple occurring after the date of separation and prior to the date of distribution, except that appreciation or diminution in value which is the result of postseparation actions or activities of a spouse shall not be treated as divisible property.

Whatever the problems of Y2K, they won't include sloppy programming which assumes every year divisible by 4 is a leap year since 2000, unlike the previous and subsequent years divisible by 100, is a leap year.
By the time the 1900 blunder was discovered, Excel users had created millions of spreadsheets containing incorrect day numbers, so Microsoft decided to leave the error in place rather than force users to convert their spreadsheets, and the error remains to this day.
Note, however, that only 1900 is affected; while the first release of Excel probably also screwed up all years divisible by 100 and hence implemented a purely Julian calendar, contemporary versions do correctly count days in 2000 (which is a leap year, being divisible by 400), 2100, and subsequent end of century years.
