For example, if 27 is divided by 6, the quotient is 4 and the remainder is 3.
If a number is divided by another number, if it is smaller than another number, the quotient is 0 and the remainder is itself.
For example: 1 divided by 2, the quotient is 0, and the remainder is1; When 2 is divided by 3, the quotient is 0 and the remainder is 2.
Summarize the relationship between the parts of multiplication and division in learning, and use these relationships to check multiplication and division. Division is the basis of advanced operation in the future, and mathematics can be used in physics, chemistry and mathematics.
Extended data
1, multi-digit division law integer division starts from high order. Divide by a few and see how many there are.
This is not enough to see the next one, except which business is which.
The remainder is less than the divisor, which is not enough for quotient one zero.
2. Quotient is constant. Dividend and divisor are multiplied at the same time, and the multiplication factors should be the same.
Divider and divisor are divided by the same number.
In addition to the multiplication and division of 0, the invariance of quotient should be clearly remembered.
When an integer A is divided by an integer b (b≠0), the quotient is exactly an integer with no remainder. We say that A is divisible by B (that is, B is divisible by A). When the quotient is an integer or a finite decimal and the remainder is 0, we say that A is divisible by B, or B is divisible by A). Here, a and b can be natural numbers.
1, the unit is the divisible number of 2: 0, 2, 4, 6, 8.
2. The characteristics of numbers that can be divisible by 5: 0 or 5 in a unit.
3. The feature that a number can be divisible by 3: the sum of the numbers on each digit of a number can be divisible by 3, and this number can also be divisible by 3.
