What are the required steps to convert base 10 decimal system
number 11 010 001 345 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;
  • 11 010 001 345 ÷ 2 = 5 505 000 672 + 1;
  • 5 505 000 672 ÷ 2 = 2 752 500 336 + 0;
  • 2 752 500 336 ÷ 2 = 1 376 250 168 + 0;
  • 1 376 250 168 ÷ 2 = 688 125 084 + 0;
  • 688 125 084 ÷ 2 = 344 062 542 + 0;
  • 344 062 542 ÷ 2 = 172 031 271 + 0;
  • 172 031 271 ÷ 2 = 86 015 635 + 1;
  • 86 015 635 ÷ 2 = 43 007 817 + 1;
  • 43 007 817 ÷ 2 = 21 503 908 + 1;
  • 21 503 908 ÷ 2 = 10 751 954 + 0;
  • 10 751 954 ÷ 2 = 5 375 977 + 0;
  • 5 375 977 ÷ 2 = 2 687 988 + 1;
  • 2 687 988 ÷ 2 = 1 343 994 + 0;
  • 1 343 994 ÷ 2 = 671 997 + 0;
  • 671 997 ÷ 2 = 335 998 + 1;
  • 335 998 ÷ 2 = 167 999 + 0;
  • 167 999 ÷ 2 = 83 999 + 1;
  • 83 999 ÷ 2 = 41 999 + 1;
  • 41 999 ÷ 2 = 20 999 + 1;
  • 20 999 ÷ 2 = 10 499 + 1;
  • 10 499 ÷ 2 = 5 249 + 1;
  • 5 249 ÷ 2 = 2 624 + 1;
  • 2 624 ÷ 2 = 1 312 + 0;
  • 1 312 ÷ 2 = 656 + 0;
  • 656 ÷ 2 = 328 + 0;
  • 328 ÷ 2 = 164 + 0;
  • 164 ÷ 2 = 82 + 0;
  • 82 ÷ 2 = 41 + 0;
  • 41 ÷ 2 = 20 + 1;
  • 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.

11 010 001 345(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

11 010 001 345 (base 10) = 10 1001 0000 0011 1111 0100 1001 1100 0001 (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)
