What are the required steps to convert base 10 decimal system
number 1 231 232 056 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;
  • 1 231 232 056 ÷ 2 = 615 616 028 + 0;
  • 615 616 028 ÷ 2 = 307 808 014 + 0;
  • 307 808 014 ÷ 2 = 153 904 007 + 0;
  • 153 904 007 ÷ 2 = 76 952 003 + 1;
  • 76 952 003 ÷ 2 = 38 476 001 + 1;
  • 38 476 001 ÷ 2 = 19 238 000 + 1;
  • 19 238 000 ÷ 2 = 9 619 000 + 0;
  • 9 619 000 ÷ 2 = 4 809 500 + 0;
  • 4 809 500 ÷ 2 = 2 404 750 + 0;
  • 2 404 750 ÷ 2 = 1 202 375 + 0;
  • 1 202 375 ÷ 2 = 601 187 + 1;
  • 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.

1 231 232 056(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 231 232 056 (base 10) = 100 1001 0110 0011 0001 1100 0011 1000 (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)
