What are the required steps to convert base 10 decimal system
number 1 129 316 048 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;
  • 1 129 316 048 ÷ 2 = 564 658 024 + 0;
  • 564 658 024 ÷ 2 = 282 329 012 + 0;
  • 282 329 012 ÷ 2 = 141 164 506 + 0;
  • 141 164 506 ÷ 2 = 70 582 253 + 0;
  • 70 582 253 ÷ 2 = 35 291 126 + 1;
  • 35 291 126 ÷ 2 = 17 645 563 + 0;
  • 17 645 563 ÷ 2 = 8 822 781 + 1;
  • 8 822 781 ÷ 2 = 4 411 390 + 1;
  • 4 411 390 ÷ 2 = 2 205 695 + 0;
  • 2 205 695 ÷ 2 = 1 102 847 + 1;
  • 1 102 847 ÷ 2 = 551 423 + 1;
  • 551 423 ÷ 2 = 275 711 + 1;
  • 275 711 ÷ 2 = 137 855 + 1;
  • 137 855 ÷ 2 = 68 927 + 1;
  • 68 927 ÷ 2 = 34 463 + 1;
  • 34 463 ÷ 2 = 17 231 + 1;
  • 17 231 ÷ 2 = 8 615 + 1;
  • 8 615 ÷ 2 = 4 307 + 1;
  • 4 307 ÷ 2 = 2 153 + 1;
  • 2 153 ÷ 2 = 1 076 + 1;
  • 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.

1 129 316 048(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 129 316 048 (base 10) = 100 0011 0100 1111 1111 1110 1101 0000 (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)
