 $5000\ \div\ 1000=\ 5$   $5000\ \div\ 10=500$  

 $5000\ \div\ 100\ =50$  

The Boy Scouts of Danao Elementary School initiated the collection of 2318 canned goods to be given to 10 poor families affected by typhoon Leo. How many pieces of canned good should each family receive? 

Try to observe the digits of the dividend is exactly the same with the first 3 digits of the quotient. Remainder is also the same digit of the last digit of the dividend. 

 In dividing 3 to 4-digit numbers by 10 with remainders, the last digit in the dividend is the remainder while the remaining digits represent the quotient. 

The first 2 digits of the dividend is exactly the same first 2 digits of the quotient. Remainder is also the same digits of the last 2 digits of the dividend.

 In dividing 3 to 4-digit numbers by 100 with remainder, the 2 digits in the dividend is the remainder while the remaining digits represent the quotient. 

The first digit of the dividend is exactly the same with first digit of the quotient. Remainder is also the same digit of the last 3 digits of the dividend. 

In dividing 4-digit numbers by 1000 with remainder, the 3 digits in the dividend is the remainder while the remaining digits represent the quotient.

Example:

3 1, 205 ÷ 48 = 650 r 5 

3 0 000 ÷ 50 = N --Round off the dividend and the divisor to their highest place value.  

3 0 000 ÷ 50 = 600-- Apply the rules for cancellation for dividing rounded numbers.
