"Dividing three digits by one digit" Dividing two or three digits by one digit PPT courseware 4

Think about it: when a three-digit number is divided by a one-digit number, when is the quotient a two-digit number? When is a quotient a three-digit number?

If the number in the hundreds place is greater than the divisor, the quotient is two digits; if the number in the hundreds place is greater than or as large as the divisor, the quotient is three digits.

The divisor is a one-digit vertical division. How should we calculate it?

(1) Starting from the high digit of the dividend, each time the divisor is used, first try to divide the previous digit of the dividend. If it is smaller than the divisor, then try to divide the first two digits.

(2) Write the quotient on the digit of the dividend you divide.

(3) Every time a quotient is found, the remaining remainder must be smaller than the divisor.

What is the quotient of each of the following questions?

(1)The quotient of 257÷5 is () digits

(2)The quotient of 804÷6 is () digits

(3)The quotient of 183÷4 is () digits

(4)The quotient of 317÷2 is () digits

Summary: How many methods of division do you remember?

(1) Starting from the high digit of the dividend, first try to divide the previous digit of the dividend. If the previous digit is smaller than the divisor, then try to divide the first two digits.

(2) Write the quotient on the digit of the dividend you divide.

(3) After each division to obtain the quotient, the remaining number must be smaller than the divisor.
