What are the required steps to convert base 10 decimal system
number 2 750 740 921 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;
  • 2 750 740 921 ÷ 2 = 1 375 370 460 + 1;
  • 1 375 370 460 ÷ 2 = 687 685 230 + 0;
  • 687 685 230 ÷ 2 = 343 842 615 + 0;
  • 343 842 615 ÷ 2 = 171 921 307 + 1;
  • 171 921 307 ÷ 2 = 85 960 653 + 1;
  • 85 960 653 ÷ 2 = 42 980 326 + 1;
  • 42 980 326 ÷ 2 = 21 490 163 + 0;
  • 21 490 163 ÷ 2 = 10 745 081 + 1;
  • 10 745 081 ÷ 2 = 5 372 540 + 1;
  • 5 372 540 ÷ 2 = 2 686 270 + 0;
  • 2 686 270 ÷ 2 = 1 343 135 + 0;
  • 1 343 135 ÷ 2 = 671 567 + 1;
  • 671 567 ÷ 2 = 335 783 + 1;
  • 335 783 ÷ 2 = 167 891 + 1;
  • 167 891 ÷ 2 = 83 945 + 1;
  • 83 945 ÷ 2 = 41 972 + 1;
  • 41 972 ÷ 2 = 20 986 + 0;
  • 20 986 ÷ 2 = 10 493 + 0;
  • 10 493 ÷ 2 = 5 246 + 1;
  • 5 246 ÷ 2 = 2 623 + 0;
  • 2 623 ÷ 2 = 1 311 + 1;
  • 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.

2 750 740 921(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 750 740 921 (base 10) = 1010 0011 1111 0100 1111 1001 1011 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)
