Eliminate decimal from divisor: Eliminate the decimal from the divisor. To divide by a decimal, we can shift the decimal point in both the divisor and the dividend to make the divisor a whole number. Since 0.61 has two decimal places, we multiply both numbers by 100. 390.4 becomes 39040 and 0.61 becomes 61.Divide the new numbers: Divide the new numbers. Now we divide 39040 by 61. 39040 ÷ 61 = 640Check for any remainder: Check for any remainder. In this case, there is no remainder, so 39040 divided by 61 is exactly 640.Verify the result: Verify the result. To ensure there are no mistakes, we can multiply the quotient by the divisor to see if we get the original dividend. 640 × 61 = 39040 Since this matches our adjusted dividend, the division is correct.

Eliminate decimal from divisor: Eliminate the decimal from the divisor. $\newline$ To divide by a decimal, we can shift the decimal point in both the divisor and the dividend to make the divisor a whole number. Since $0.61$ has two decimal places, we multiply both numbers by $100$ . $\newline$ $390.4$ becomes $39040$ and $0.61$ becomes $61$ .
Divide the new numbers: Divide the new numbers. $\newline$ Now we divide $39040$ by $61$ . $\newline$ $39040 \div 61 = 640$
Check for any remainder: Check for any remainder. $\newline$ In this case, there is no remainder, so $39040$ divided by $61$ is exactly $640$ .
Verify the result: Verify the result. $\newline$ To ensure there are no mistakes, we can multiply the quotient by the divisor to see if we get the original dividend. $\newline$ $640 \times 61 = 39040$ $\newline$ Since this matches our adjusted dividend, the division is correct.
