What are the required steps to convert base 10 decimal system
number 2 154 959 734 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;
  • 2 154 959 734 ÷ 2 = 1 077 479 867 + 0;
  • 1 077 479 867 ÷ 2 = 538 739 933 + 1;
  • 538 739 933 ÷ 2 = 269 369 966 + 1;
  • 269 369 966 ÷ 2 = 134 684 983 + 0;
  • 134 684 983 ÷ 2 = 67 342 491 + 1;
  • 67 342 491 ÷ 2 = 33 671 245 + 1;
  • 33 671 245 ÷ 2 = 16 835 622 + 1;
  • 16 835 622 ÷ 2 = 8 417 811 + 0;
  • 8 417 811 ÷ 2 = 4 208 905 + 1;
  • 4 208 905 ÷ 2 = 2 104 452 + 1;
  • 2 104 452 ÷ 2 = 1 052 226 + 0;
  • 1 052 226 ÷ 2 = 526 113 + 0;
  • 526 113 ÷ 2 = 263 056 + 1;
  • 263 056 ÷ 2 = 131 528 + 0;
  • 131 528 ÷ 2 = 65 764 + 0;
  • 65 764 ÷ 2 = 32 882 + 0;
  • 32 882 ÷ 2 = 16 441 + 0;
  • 16 441 ÷ 2 = 8 220 + 1;
  • 8 220 ÷ 2 = 4 110 + 0;
  • 4 110 ÷ 2 = 2 055 + 0;
  • 2 055 ÷ 2 = 1 027 + 1;
  • 1 027 ÷ 2 = 513 + 1;
  • 513 ÷ 2 = 256 + 1;
  • 256 ÷ 2 = 128 + 0;
  • 128 ÷ 2 = 64 + 0;
  • 64 ÷ 2 = 32 + 0;
  • 32 ÷ 2 = 16 + 0;
  • 16 ÷ 2 = 8 + 0;
  • 8 ÷ 2 = 4 + 0;
  • 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.

2 154 959 734(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 154 959 734 (base 10) = 1000 0000 0111 0010 0001 0011 0111 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)
