  "content": "<p>Decimal to octal conversion is the process of converting a decimal (base-10) number into its octal (base-8) representation.</p><p>In the decimal system, numbers are expressed using the digits 0 through 9, and in the octal system, numbers are represented using the digits 0 through 7.</p><h2>Steps to convert decimal to octal</h2><p>Here are the steps to convert a decimal number to octal:</p><ol class=\"steps\"><li>Divide the decimal number by 8.</li><li>Record the remainder (which can be any digit from 0 to 7).</li><li>Divide the quotient obtained in step 1 by 8.</li><li>Record the remainder again.</li><li>Repeat steps 3 and 4 until the quotient becomes 0.</li><li>The octal equivalent is the sequence of remainders read in reverse order.</li></ol><h2>Example</h2><p>Let's take an example to illustrate the process. Suppose we want to convert the decimal number 85 to octal:</p><ol class=\"steps\"><li>85÷8 = 10 with a remainder of <strong>5</strong>. Record the remainder.</li><li>10÷8 = 1 with a remainder of <strong>2</strong>. Record the remainder.</li><li>1÷8 = 0 with a remainder of <strong>1</strong>. Record the remainder.</li></ol><p>Reading the remainders in reverse order gives us the octal equivalent: <strong>125</strong>.</p><p>Therefore, <strong>85</strong> in decimal is equal to <strong>125</strong> in octal.</p>"
