What are the required steps to convert base 10 decimal system
number 1 088 421 911 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;
  • 1 088 421 911 ÷ 2 = 544 210 955 + 1;
  • 544 210 955 ÷ 2 = 272 105 477 + 1;
  • 272 105 477 ÷ 2 = 136 052 738 + 1;
  • 136 052 738 ÷ 2 = 68 026 369 + 0;
  • 68 026 369 ÷ 2 = 34 013 184 + 1;
  • 34 013 184 ÷ 2 = 17 006 592 + 0;
  • 17 006 592 ÷ 2 = 8 503 296 + 0;
  • 8 503 296 ÷ 2 = 4 251 648 + 0;
  • 4 251 648 ÷ 2 = 2 125 824 + 0;
  • 2 125 824 ÷ 2 = 1 062 912 + 0;
  • 1 062 912 ÷ 2 = 531 456 + 0;
  • 531 456 ÷ 2 = 265 728 + 0;
  • 265 728 ÷ 2 = 132 864 + 0;
  • 132 864 ÷ 2 = 66 432 + 0;
  • 66 432 ÷ 2 = 33 216 + 0;
  • 33 216 ÷ 2 = 16 608 + 0;
  • 16 608 ÷ 2 = 8 304 + 0;
  • 8 304 ÷ 2 = 4 152 + 0;
  • 4 152 ÷ 2 = 2 076 + 0;
  • 2 076 ÷ 2 = 1 038 + 0;
  • 1 038 ÷ 2 = 519 + 0;
  • 519 ÷ 2 = 259 + 1;
  • 259 ÷ 2 = 129 + 1;
  • 129 ÷ 2 = 64 + 1;
  • 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.

1 088 421 911(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 088 421 911 (base 10) = 100 0000 1110 0000 0000 0000 0001 0111 (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)
