See below how to convert 10 100 100 177(10), the unsigned base 10 decimal system number to base 2 binary equivalent

What are the required steps to convert base 10 decimal system
number 10 100 100 177 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;
  • 10 100 100 177 ÷ 2 = 5 050 050 088 + 1;
  • 5 050 050 088 ÷ 2 = 2 525 025 044 + 0;
  • 2 525 025 044 ÷ 2 = 1 262 512 522 + 0;
  • 1 262 512 522 ÷ 2 = 631 256 261 + 0;
  • 631 256 261 ÷ 2 = 315 628 130 + 1;
  • 315 628 130 ÷ 2 = 157 814 065 + 0;
  • 157 814 065 ÷ 2 = 78 907 032 + 1;
  • 78 907 032 ÷ 2 = 39 453 516 + 0;
  • 39 453 516 ÷ 2 = 19 726 758 + 0;
  • 19 726 758 ÷ 2 = 9 863 379 + 0;
  • 9 863 379 ÷ 2 = 4 931 689 + 1;
  • 4 931 689 ÷ 2 = 2 465 844 + 1;
  • 2 465 844 ÷ 2 = 1 232 922 + 0;
  • 1 232 922 ÷ 2 = 616 461 + 0;
  • 616 461 ÷ 2 = 308 230 + 1;
  • 308 230 ÷ 2 = 154 115 + 0;
  • 154 115 ÷ 2 = 77 057 + 1;
  • 77 057 ÷ 2 = 38 528 + 1;
  • 38 528 ÷ 2 = 19 264 + 0;
  • 19 264 ÷ 2 = 9 632 + 0;
  • 9 632 ÷ 2 = 4 816 + 0;
  • 4 816 ÷ 2 = 2 408 + 0;
  • 2 408 ÷ 2 = 1 204 + 0;
  • 1 204 ÷ 2 = 602 + 0;
  • 602 ÷ 2 = 301 + 0;
  • 301 ÷ 2 = 150 + 1;
  • 150 ÷ 2 = 75 + 0;
  • 75 ÷ 2 = 37 + 1;
  • 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.

10 100 100 177(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

10 100 100 177 (base 10) = 10 0101 1010 0000 0011 0100 1100 0101 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)
