What are the required steps to convert base 10 decimal system
number 2 600 689 989 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;
  • 2 600 689 989 ÷ 2 = 1 300 344 994 + 1;
  • 1 300 344 994 ÷ 2 = 650 172 497 + 0;
  • 650 172 497 ÷ 2 = 325 086 248 + 1;
  • 325 086 248 ÷ 2 = 162 543 124 + 0;
  • 162 543 124 ÷ 2 = 81 271 562 + 0;
  • 81 271 562 ÷ 2 = 40 635 781 + 0;
  • 40 635 781 ÷ 2 = 20 317 890 + 1;
  • 20 317 890 ÷ 2 = 10 158 945 + 0;
  • 10 158 945 ÷ 2 = 5 079 472 + 1;
  • 5 079 472 ÷ 2 = 2 539 736 + 0;
  • 2 539 736 ÷ 2 = 1 269 868 + 0;
  • 1 269 868 ÷ 2 = 634 934 + 0;
  • 634 934 ÷ 2 = 317 467 + 0;
  • 317 467 ÷ 2 = 158 733 + 1;
  • 158 733 ÷ 2 = 79 366 + 1;
  • 79 366 ÷ 2 = 39 683 + 0;
  • 39 683 ÷ 2 = 19 841 + 1;
  • 19 841 ÷ 2 = 9 920 + 1;
  • 9 920 ÷ 2 = 4 960 + 0;
  • 4 960 ÷ 2 = 2 480 + 0;
  • 2 480 ÷ 2 = 1 240 + 0;
  • 1 240 ÷ 2 = 620 + 0;
  • 620 ÷ 2 = 310 + 0;
  • 310 ÷ 2 = 155 + 0;
  • 155 ÷ 2 = 77 + 1;
  • 77 ÷ 2 = 38 + 1;
  • 38 ÷ 2 = 19 + 0;
  • 19 ÷ 2 = 9 + 1;
  • 9 ÷ 2 = 4 + 1;
  • 4 ÷ 2 = 2 + 0;
  • 2 ÷ 2 = 1 + 0;
  • 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.

2 600 689 989(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 600 689 989 (base 10) = 1001 1011 0000 0011 0110 0001 0100 0101 (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)
