What are the required steps to convert base 10 decimal system
number 1 970 168 871 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;
  • 1 970 168 871 ÷ 2 = 985 084 435 + 1;
  • 985 084 435 ÷ 2 = 492 542 217 + 1;
  • 492 542 217 ÷ 2 = 246 271 108 + 1;
  • 246 271 108 ÷ 2 = 123 135 554 + 0;
  • 123 135 554 ÷ 2 = 61 567 777 + 0;
  • 61 567 777 ÷ 2 = 30 783 888 + 1;
  • 30 783 888 ÷ 2 = 15 391 944 + 0;
  • 15 391 944 ÷ 2 = 7 695 972 + 0;
  • 7 695 972 ÷ 2 = 3 847 986 + 0;
  • 3 847 986 ÷ 2 = 1 923 993 + 0;
  • 1 923 993 ÷ 2 = 961 996 + 1;
  • 961 996 ÷ 2 = 480 998 + 0;
  • 480 998 ÷ 2 = 240 499 + 0;
  • 240 499 ÷ 2 = 120 249 + 1;
  • 120 249 ÷ 2 = 60 124 + 1;
  • 60 124 ÷ 2 = 30 062 + 0;
  • 30 062 ÷ 2 = 15 031 + 0;
  • 15 031 ÷ 2 = 7 515 + 1;
  • 7 515 ÷ 2 = 3 757 + 1;
  • 3 757 ÷ 2 = 1 878 + 1;
  • 1 878 ÷ 2 = 939 + 0;
  • 939 ÷ 2 = 469 + 1;
  • 469 ÷ 2 = 234 + 1;
  • 234 ÷ 2 = 117 + 0;
  • 117 ÷ 2 = 58 + 1;
  • 58 ÷ 2 = 29 + 0;
  • 29 ÷ 2 = 14 + 1;
  • 14 ÷ 2 = 7 + 0;
  • 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.

1 970 168 871(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 970 168 871 (base 10) = 111 0101 0110 1110 0110 0100 0010 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)
