What are the required steps to convert base 10 decimal system
number 1 231 231 753 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;
  • 1 231 231 753 ÷ 2 = 615 615 876 + 1;
  • 615 615 876 ÷ 2 = 307 807 938 + 0;
  • 307 807 938 ÷ 2 = 153 903 969 + 0;
  • 153 903 969 ÷ 2 = 76 951 984 + 1;
  • 76 951 984 ÷ 2 = 38 475 992 + 0;
  • 38 475 992 ÷ 2 = 19 237 996 + 0;
  • 19 237 996 ÷ 2 = 9 618 998 + 0;
  • 9 618 998 ÷ 2 = 4 809 499 + 0;
  • 4 809 499 ÷ 2 = 2 404 749 + 1;
  • 2 404 749 ÷ 2 = 1 202 374 + 1;
  • 1 202 374 ÷ 2 = 601 187 + 0;
  • 601 187 ÷ 2 = 300 593 + 1;
  • 300 593 ÷ 2 = 150 296 + 1;
  • 150 296 ÷ 2 = 75 148 + 0;
  • 75 148 ÷ 2 = 37 574 + 0;
  • 37 574 ÷ 2 = 18 787 + 0;
  • 18 787 ÷ 2 = 9 393 + 1;
  • 9 393 ÷ 2 = 4 696 + 1;
  • 4 696 ÷ 2 = 2 348 + 0;
  • 2 348 ÷ 2 = 1 174 + 0;
  • 1 174 ÷ 2 = 587 + 0;
  • 587 ÷ 2 = 293 + 1;
  • 293 ÷ 2 = 146 + 1;
  • 146 ÷ 2 = 73 + 0;
  • 73 ÷ 2 = 36 + 1;
  • 36 ÷ 2 = 18 + 0;
  • 18 ÷ 2 = 9 + 0;
  • 9 ÷ 2 = 4 + 1;
  • 4 ÷ 2 = 2 + 0;
  • 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.

1 231 231 753(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 231 231 753 (base 10) = 100 1001 0110 0011 0001 1011 0000 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)
