What are the required steps to convert base 10 decimal system
number 2 139 095 017 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;
  • 2 139 095 017 ÷ 2 = 1 069 547 508 + 1;
  • 1 069 547 508 ÷ 2 = 534 773 754 + 0;
  • 534 773 754 ÷ 2 = 267 386 877 + 0;
  • 267 386 877 ÷ 2 = 133 693 438 + 1;
  • 133 693 438 ÷ 2 = 66 846 719 + 0;
  • 66 846 719 ÷ 2 = 33 423 359 + 1;
  • 33 423 359 ÷ 2 = 16 711 679 + 1;
  • 16 711 679 ÷ 2 = 8 355 839 + 1;
  • 8 355 839 ÷ 2 = 4 177 919 + 1;
  • 4 177 919 ÷ 2 = 2 088 959 + 1;
  • 2 088 959 ÷ 2 = 1 044 479 + 1;
  • 1 044 479 ÷ 2 = 522 239 + 1;
  • 522 239 ÷ 2 = 261 119 + 1;
  • 261 119 ÷ 2 = 130 559 + 1;
  • 130 559 ÷ 2 = 65 279 + 1;
  • 65 279 ÷ 2 = 32 639 + 1;
  • 32 639 ÷ 2 = 16 319 + 1;
  • 16 319 ÷ 2 = 8 159 + 1;
  • 8 159 ÷ 2 = 4 079 + 1;
  • 4 079 ÷ 2 = 2 039 + 1;
  • 2 039 ÷ 2 = 1 019 + 1;
  • 1 019 ÷ 2 = 509 + 1;
  • 509 ÷ 2 = 254 + 1;
  • 254 ÷ 2 = 127 + 0;
  • 127 ÷ 2 = 63 + 1;
  • 63 ÷ 2 = 31 + 1;
  • 31 ÷ 2 = 15 + 1;
  • 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.

2 139 095 017(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 139 095 017 (base 10) = 111 1111 0111 1111 1111 1111 1110 1001 (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)
