What are the required steps to convert base 10 decimal system
number 1 128 792 023 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;
  • 1 128 792 023 ÷ 2 = 564 396 011 + 1;
  • 564 396 011 ÷ 2 = 282 198 005 + 1;
  • 282 198 005 ÷ 2 = 141 099 002 + 1;
  • 141 099 002 ÷ 2 = 70 549 501 + 0;
  • 70 549 501 ÷ 2 = 35 274 750 + 1;
  • 35 274 750 ÷ 2 = 17 637 375 + 0;
  • 17 637 375 ÷ 2 = 8 818 687 + 1;
  • 8 818 687 ÷ 2 = 4 409 343 + 1;
  • 4 409 343 ÷ 2 = 2 204 671 + 1;
  • 2 204 671 ÷ 2 = 1 102 335 + 1;
  • 1 102 335 ÷ 2 = 551 167 + 1;
  • 551 167 ÷ 2 = 275 583 + 1;
  • 275 583 ÷ 2 = 137 791 + 1;
  • 137 791 ÷ 2 = 68 895 + 1;
  • 68 895 ÷ 2 = 34 447 + 1;
  • 34 447 ÷ 2 = 17 223 + 1;
  • 17 223 ÷ 2 = 8 611 + 1;
  • 8 611 ÷ 2 = 4 305 + 1;
  • 4 305 ÷ 2 = 2 152 + 1;
  • 2 152 ÷ 2 = 1 076 + 0;
  • 1 076 ÷ 2 = 538 + 0;
  • 538 ÷ 2 = 269 + 0;
  • 269 ÷ 2 = 134 + 1;
  • 134 ÷ 2 = 67 + 0;
  • 67 ÷ 2 = 33 + 1;
  • 33 ÷ 2 = 16 + 1;
  • 16 ÷ 2 = 8 + 0;
  • 8 ÷ 2 = 4 + 0;
  • 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.

1 128 792 023(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 128 792 023 (base 10) = 100 0011 0100 0111 1111 1111 1101 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)
