Dividing 3-Digit Numbers
How to divide a three digit number by a one digit number (for example, 416 ÷ 7).
Place the divisor (7) before the division bracket and place the dividend (416) under it:
Examine the first digit of the dividend(4). It is smaller than 7 so it can't be divided by 7 to produce a whole number. Next take the first two digits of the dividend (41) and determine how many 7's it contains. In this case 41 holds five sevens (5*7=35) but not six (6*7=42). Place the 5 above the division bracket.
Multiply the 5 by 7 and place the result (35) below the 41 of the dividend.
Draw a line under the 35 and subtract it from 41 (41-35=6). Bring down the 6 from the 416 and place it to the right of the 6.
Multiply the 9 of the quotient by the divisor (7) to get 63 and place this below the 63 under the dividend. Subtract 63 from 63 to give an answer of 3. The number 3 is called the remainder and indicates that there were three left over.
