What are the required steps to convert base 10 decimal system
number 10 001 099 889 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;
  • 10 001 099 889 ÷ 2 = 5 000 549 944 + 1;
  • 5 000 549 944 ÷ 2 = 2 500 274 972 + 0;
  • 2 500 274 972 ÷ 2 = 1 250 137 486 + 0;
  • 1 250 137 486 ÷ 2 = 625 068 743 + 0;
  • 625 068 743 ÷ 2 = 312 534 371 + 1;
  • 312 534 371 ÷ 2 = 156 267 185 + 1;
  • 156 267 185 ÷ 2 = 78 133 592 + 1;
  • 78 133 592 ÷ 2 = 39 066 796 + 0;
  • 39 066 796 ÷ 2 = 19 533 398 + 0;
  • 19 533 398 ÷ 2 = 9 766 699 + 0;
  • 9 766 699 ÷ 2 = 4 883 349 + 1;
  • 4 883 349 ÷ 2 = 2 441 674 + 1;
  • 2 441 674 ÷ 2 = 1 220 837 + 0;
  • 1 220 837 ÷ 2 = 610 418 + 1;
  • 610 418 ÷ 2 = 305 209 + 0;
  • 305 209 ÷ 2 = 152 604 + 1;
  • 152 604 ÷ 2 = 76 302 + 0;
  • 76 302 ÷ 2 = 38 151 + 0;
  • 38 151 ÷ 2 = 19 075 + 1;
  • 19 075 ÷ 2 = 9 537 + 1;
  • 9 537 ÷ 2 = 4 768 + 1;
  • 4 768 ÷ 2 = 2 384 + 0;
  • 2 384 ÷ 2 = 1 192 + 0;
  • 1 192 ÷ 2 = 596 + 0;
  • 596 ÷ 2 = 298 + 0;
  • 298 ÷ 2 = 149 + 0;
  • 149 ÷ 2 = 74 + 1;
  • 74 ÷ 2 = 37 + 0;
  • 37 ÷ 2 = 18 + 1;
  • 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.

10 001 099 889(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

10 001 099 889 (base 10) = 10 0101 0100 0001 1100 1010 1100 0111 0001 (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)
