Explanation Given information: The expression is 0.4 20 . Explanation: The steps for dividing by a decimal are as follows: Change the divisor into a whole number by moving the decimal point in the divisor to its right by as many spaces as required. Here, the divisor is 0.4 . To write it as a whole number, shift the decimal point one place to the right. Thus, it becomes 4. . In the dividend, move the decimal point by the same number of places as in the divisor. Here, the dividend is 20 which is already a whole number. Therefore, insert one 0 after 20 . Thus, the dividend now becomes 200. . Now, in the quotient, the decimal point should be exactly above the decimal point of the dividend as shown below: 4. . 200. Now continue the division in the same way as with whole numbers. First digit of the dividend is 2 and 2 is less than 4 . Divide the first two digits 20 by 4 . 20 ÷ 4 = 5 with 0 left. 4 . 5 . 200. − 20 _ 0 Now bring down the 0 next 0 . Thus it becomes 00
