Short Division 1. set up the division problem 2. divide the first digit of the dividend by the divisor, if possible. Write the partial quotient in the correct place value above the division symbol (Ex. 6 ÷ 4 = 1 Write the 1 in the quotient above the thousands place because that is the place that was divided by the 4) 3. multiply the partial quotient (1) by the divisor (4) and mentally subtract it from the first digit of the dividend (6) ( 1 ● 4 = 4 and 6 – 4 = 2 ) 4. If there is a difference between the two numbers write it small in front of the next digit in the dividend to make a 2 digit number. ( write the 2 before the 5 making it 25) 5. Divide that 2 digit number by the divisor and repeat steps 2-4 until there is a dividend too small to divide by the divisor, that is the remainder. (25 ÷ 4 = 6 R1, write the 6 as the next digit in the quotient. Write the 1 in front of the 3 making it 13. Then 13 ÷ 4 = 3, write the 3 in the quotient. 3 ● 4 = 12. Mentally subtract 13 – 12 = 1. Write the 1 before the next digit in the dividend, the 2, to make it 12. Then 12 ÷ 4 = 3 Write the 3 in the quotient. 3 ● 4 = 12 12 – 12 = 0 so there is no remainder.
