What are the required steps to convert base 10 decimal system
number 4 273 946 373 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;
  • 4 273 946 373 ÷ 2 = 2 136 973 186 + 1;
  • 2 136 973 186 ÷ 2 = 1 068 486 593 + 0;
  • 1 068 486 593 ÷ 2 = 534 243 296 + 1;
  • 534 243 296 ÷ 2 = 267 121 648 + 0;
  • 267 121 648 ÷ 2 = 133 560 824 + 0;
  • 133 560 824 ÷ 2 = 66 780 412 + 0;
  • 66 780 412 ÷ 2 = 33 390 206 + 0;
  • 33 390 206 ÷ 2 = 16 695 103 + 0;
  • 16 695 103 ÷ 2 = 8 347 551 + 1;
  • 8 347 551 ÷ 2 = 4 173 775 + 1;
  • 4 173 775 ÷ 2 = 2 086 887 + 1;
  • 2 086 887 ÷ 2 = 1 043 443 + 1;
  • 1 043 443 ÷ 2 = 521 721 + 1;
  • 521 721 ÷ 2 = 260 860 + 1;
  • 260 860 ÷ 2 = 130 430 + 0;
  • 130 430 ÷ 2 = 65 215 + 0;
  • 65 215 ÷ 2 = 32 607 + 1;
  • 32 607 ÷ 2 = 16 303 + 1;
  • 16 303 ÷ 2 = 8 151 + 1;
  • 8 151 ÷ 2 = 4 075 + 1;
  • 4 075 ÷ 2 = 2 037 + 1;
  • 2 037 ÷ 2 = 1 018 + 1;
  • 1 018 ÷ 2 = 509 + 0;
  • 509 ÷ 2 = 254 + 1;
  • 254 ÷ 2 = 127 + 0;
  • 127 ÷ 2 = 63 + 1;
  • 63 ÷ 2 = 31 + 1;
  • 31 ÷ 2 = 15 + 1;
  • 15 ÷ 2 = 7 + 1;
  • 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.

4 273 946 373(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

4 273 946 373 (base 10) = 1111 1110 1011 1111 0011 1111 0000 0101 (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)
