What are the required steps to convert base 10 decimal system
number 36 999 999 673 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;
  • 36 999 999 673 ÷ 2 = 18 499 999 836 + 1;
  • 18 499 999 836 ÷ 2 = 9 249 999 918 + 0;

  • 2 312 499 979 ÷ 2 = 1 156 249 989 + 1;
  • 1 156 249 989 ÷ 2 = 578 124 994 + 1;
  • 578 124 994 ÷ 2 = 289 062 497 + 0;
  • 289 062 497 ÷ 2 = 144 531 248 + 1;
  • 144 531 248 ÷ 2 = 72 265 624 + 0;
  • 72 265 624 ÷ 2 = 36 132 812 + 0;
  • 36 132 812 ÷ 2 = 18 066 406 + 0;
  • 18 066 406 ÷ 2 = 9 033 203 + 0;
  • 9 033 203 ÷ 2 = 4 516 601 + 1;
  • 4 516 601 ÷ 2 = 2 258 300 + 1;
  • 2 258 300 ÷ 2 = 1 129 150 + 0;
  • 1 129 150 ÷ 2 = 564 575 + 0;
  • 564 575 ÷ 2 = 282 287 + 1;
  • 282 287 ÷ 2 = 141 143 + 1;
  • 141 143 ÷ 2 = 70 571 + 1;
  • 70 571 ÷ 2 = 35 285 + 1;
  • 35 285 ÷ 2 = 17 642 + 1;
  • 17 642 ÷ 2 = 8 821 + 0;
  • 8 821 ÷ 2 = 4 410 + 1;
  • 4 410 ÷ 2 = 2 205 + 0;
  • 2 205 ÷ 2 = 1 102 + 1;
  • 1 102 ÷ 2 = 551 + 0;
  • 551 ÷ 2 = 275 + 1;
  • 275 ÷ 2 = 137 + 1;
  • 137 ÷ 2 = 68 + 1;
  • 68 ÷ 2 = 34 + 0;
  • 34 ÷ 2 = 17 + 0;
  • 17 ÷ 2 = 8 + 1;
  • 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.

36 999 999 673(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

36 999 999 673 (base 10) = 1000 1001 1101 0101 1111 0011 0000 1011 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)
