See below how to convert 1 010 000 278(10), the unsigned base 10 decimal system number to base 2 binary equivalent

What are the required steps to convert base 10 decimal system
number 1 010 000 278 to base 2 unsigned binary equivalent?

  • A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.

1. Divide the number repeatedly by 2:

Keep track of each remainder.

Stop when you get a quotient that is equal to zero.


  • division = quotient + remainder;
  • 1 010 000 278 ÷ 2 = 505 000 139 + 0;
  • 505 000 139 ÷ 2 = 252 500 069 + 1;
  • 252 500 069 ÷ 2 = 126 250 034 + 1;
  • 126 250 034 ÷ 2 = 63 125 017 + 0;
  • 63 125 017 ÷ 2 = 31 562 508 + 1;
  • 31 562 508 ÷ 2 = 15 781 254 + 0;
  • 15 781 254 ÷ 2 = 7 890 627 + 0;
  • 7 890 627 ÷ 2 = 3 945 313 + 1;
  • 3 945 313 ÷ 2 = 1 972 656 + 1;
  • 1 972 656 ÷ 2 = 986 328 + 0;
  • 986 328 ÷ 2 = 493 164 + 0;
  • 493 164 ÷ 2 = 246 582 + 0;
  • 246 582 ÷ 2 = 123 291 + 0;
  • 123 291 ÷ 2 = 61 645 + 1;
  • 61 645 ÷ 2 = 30 822 + 1;
  • 30 822 ÷ 2 = 15 411 + 0;
  • 15 411 ÷ 2 = 7 705 + 1;
  • 7 705 ÷ 2 = 3 852 + 1;
  • 3 852 ÷ 2 = 1 926 + 0;
  • 1 926 ÷ 2 = 963 + 0;
  • 963 ÷ 2 = 481 + 1;
  • 481 ÷ 2 = 240 + 1;
  • 240 ÷ 2 = 120 + 0;
  • 120 ÷ 2 = 60 + 0;
  • 60 ÷ 2 = 30 + 0;
  • 30 ÷ 2 = 15 + 0;
  • 15 ÷ 2 = 7 + 1;
  • 7 ÷ 2 = 3 + 1;
  • 3 ÷ 2 = 1 + 1;
  • 1 ÷ 2 = 0 + 1;

2. Construct the base 2 representation of the positive number:

Take all the remainders starting from the bottom of the list constructed above.

1 010 000 278(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 010 000 278 (base 10) = 11 1100 0011 0011 0110 0001 1001 0110 (base 2)

Spaces were used to group digits: for binary, by 4, for decimal, by 3.

How to convert unsigned integer numbers (positive) from decimal system (base 10) to binary = simply convert from base 10 to base 2

Follow the steps below to convert a base ten unsigned integer number to base two:

  • 1. Divide repeatedly by 2 the positive integer number that has to be converted to binary, keeping track of each remainder, until we get a QUOTIENT that is equal to ZERO.
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above. Thus, the last remainder of the divisions becomes the first symbol (the leftmost) of the base two number, while the first remainder becomes the last symbol (the rightmost).

Example: convert the positive integer number 55 from decimal system (base ten) to binary code (base two):

  • 1. Divide repeatedly 55 by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
    • division = quotient + remainder;
    • 55 ÷ 2 = 27 + 1;
    • 27 ÷ 2 = 13 + 1;
    • 13 ÷ 2 = 6 + 1;
    • 6 ÷ 2 = 3 + 0;
    • 3 ÷ 2 = 1 + 1;
    • 1 ÷ 2 = 0 + 1;
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above:
  • 55(10) = 11 0111(2)
  • Number 5510, positive integer (no sign), converted from decimal system (base 10) to unsigned binary (base 2) = 11 0111(2)
