What are the required steps to convert base 10 decimal system
number 11 000 109 955 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;
  • 11 000 109 955 ÷ 2 = 5 500 054 977 + 1;
  • 5 500 054 977 ÷ 2 = 2 750 027 488 + 1;
  • 2 750 027 488 ÷ 2 = 1 375 013 744 + 0;
  • 1 375 013 744 ÷ 2 = 687 506 872 + 0;
  • 687 506 872 ÷ 2 = 343 753 436 + 0;
  • 343 753 436 ÷ 2 = 171 876 718 + 0;
  • 171 876 718 ÷ 2 = 85 938 359 + 0;
  • 85 938 359 ÷ 2 = 42 969 179 + 1;
  • 42 969 179 ÷ 2 = 21 484 589 + 1;
  • 21 484 589 ÷ 2 = 10 742 294 + 1;
  • 10 742 294 ÷ 2 = 5 371 147 + 0;
  • 5 371 147 ÷ 2 = 2 685 573 + 1;
  • 2 685 573 ÷ 2 = 1 342 786 + 1;
  • 1 342 786 ÷ 2 = 671 393 + 0;
  • 671 393 ÷ 2 = 335 696 + 1;
  • 335 696 ÷ 2 = 167 848 + 0;
  • 167 848 ÷ 2 = 83 924 + 0;
  • 83 924 ÷ 2 = 41 962 + 0;
  • 41 962 ÷ 2 = 20 981 + 0;
  • 20 981 ÷ 2 = 10 490 + 1;
  • 10 490 ÷ 2 = 5 245 + 0;
  • 5 245 ÷ 2 = 2 622 + 1;
  • 2 622 ÷ 2 = 1 311 + 0;
  • 1 311 ÷ 2 = 655 + 1;
  • 655 ÷ 2 = 327 + 1;
  • 327 ÷ 2 = 163 + 1;
  • 163 ÷ 2 = 81 + 1;
  • 81 ÷ 2 = 40 + 1;
  • 40 ÷ 2 = 20 + 0;
  • 20 ÷ 2 = 10 + 0;
  • 10 ÷ 2 = 5 + 0;
  • 5 ÷ 2 = 2 + 1;
  • 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.

11 000 109 955(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

11 000 109 955 (base 10) = 10 1000 1111 1010 1000 0101 1011 1000 0011 (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)
