Let's convert the decimal number 991 to binary without using a calculator:

Step 1: Divide by 2

Start by dividing 991 by 2:

991 ÷ 2 = 495 (Quotient) with a remainder of 1

Step 2: Divide the Quotient

Now, divide the quotient (495) by 2:

495 ÷ 2 = 247 (Quotient) with a remainder of 1

Step 3: Divide the Quotient

Now, divide the quotient (247) by 2:

247 ÷ 2 = 123 (Quotient) with a remainder of 1

Step 4: Divide the Quotient

Now, divide the quotient (123) by 2:

123 ÷ 2 = 61 (Quotient) with a remainder of 1

Step 5: Divide the Quotient

Now, divide the quotient (61) by 2:

61 ÷ 2 = 30 (Quotient) with a remainder of 1

Step 6: Divide the Quotient

Now, divide the quotient (30) by 2:

30 ÷ 2 = 15 (Quotient) with a remainder of 0

Step 7: Divide the Quotient

Now, divide the quotient (15) by 2:

15 ÷ 2 = 7 (Quotient) with a remainder of 1

Step 8: Divide the Quotient

Now, divide the quotient (7) by 2:

7 ÷ 2 = 3 (Quotient) with a remainder of 1

Step 9: Divide the Quotient

Now, divide the quotient (3) by 2:

3 ÷ 2 = 1 (Quotient) with a remainder of 1

Step 10: Final actions

The Quotient is less than 2 (1), so we will transfer it to the beginning of the number as a reminder.

Step 11: Write the Remainders in Reverse Order

Now, write down the remainders obtained in reverse order:
