What are the required steps to convert base 10 decimal system
number 3 518 890 169 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;
  • 3 518 890 169 ÷ 2 = 1 759 445 084 + 1;
  • 1 759 445 084 ÷ 2 = 879 722 542 + 0;
  • 879 722 542 ÷ 2 = 439 861 271 + 0;
  • 439 861 271 ÷ 2 = 219 930 635 + 1;
  • 219 930 635 ÷ 2 = 109 965 317 + 1;
  • 109 965 317 ÷ 2 = 54 982 658 + 1;
  • 54 982 658 ÷ 2 = 27 491 329 + 0;
  • 27 491 329 ÷ 2 = 13 745 664 + 1;
  • 13 745 664 ÷ 2 = 6 872 832 + 0;
  • 6 872 832 ÷ 2 = 3 436 416 + 0;
  • 3 436 416 ÷ 2 = 1 718 208 + 0;
  • 1 718 208 ÷ 2 = 859 104 + 0;
  • 859 104 ÷ 2 = 429 552 + 0;
  • 429 552 ÷ 2 = 214 776 + 0;
  • 214 776 ÷ 2 = 107 388 + 0;
  • 107 388 ÷ 2 = 53 694 + 0;
  • 53 694 ÷ 2 = 26 847 + 0;
  • 26 847 ÷ 2 = 13 423 + 1;
  • 13 423 ÷ 2 = 6 711 + 1;
  • 6 711 ÷ 2 = 3 355 + 1;
  • 3 355 ÷ 2 = 1 677 + 1;
  • 1 677 ÷ 2 = 838 + 1;
  • 838 ÷ 2 = 419 + 0;
  • 419 ÷ 2 = 209 + 1;
  • 209 ÷ 2 = 104 + 1;
  • 104 ÷ 2 = 52 + 0;
  • 52 ÷ 2 = 26 + 0;
  • 26 ÷ 2 = 13 + 0;
  • 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 number:

Take all the remainders starting from the bottom of the list constructed above.

3 518 890 169(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 518 890 169 (base 10) = 1101 0001 1011 1110 0000 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)
