calculation formula: 52÷2= 26, test: 2× 26 = 52, the calculation is correct. the product of two factors is known to be with one of them, and the operation of finding the other factor is called division.

52 divided by 2 is calculated vertically

the law of division

in integer division, the divisor must be less than the divisor to be carried out, when the divisor does not exceed two digits, the divisor is a single digit, and the quotient is also a single digit, the quotient and the remainder (the remainder may be zero) can be directly derived according to the multiplication trick, called the division in the table; divisions that are divised by more than two digits are called multi-digit division.

the arithmetic nature of division

1, the divisor is expanded (reduced) n times, the divisor is unchanged, and the quotient is also expanded (reduced) n times accordingly.

2, the divisor expands (shrinks) n times, the divisor does not change, the quotient correspondingly shrinks (expands) n times.

(3) the divisor is divided by two divisors consecutively, which is equal to the product of dividing by these two divisors. sometimes it can be done easily depending on the nature of the division. for example: 300÷25÷4 = 300 ÷ (25×4) divided by a number = the reciprocal of this number.
