What are the required steps to convert base 10 decimal system
number 3 800 851 563 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;
  • 3 800 851 563 ÷ 2 = 1 900 425 781 + 1;
  • 1 900 425 781 ÷ 2 = 950 212 890 + 1;
  • 950 212 890 ÷ 2 = 475 106 445 + 0;
  • 475 106 445 ÷ 2 = 237 553 222 + 1;
  • 237 553 222 ÷ 2 = 118 776 611 + 0;
  • 118 776 611 ÷ 2 = 59 388 305 + 1;
  • 59 388 305 ÷ 2 = 29 694 152 + 1;
  • 29 694 152 ÷ 2 = 14 847 076 + 0;
  • 14 847 076 ÷ 2 = 7 423 538 + 0;
  • 7 423 538 ÷ 2 = 3 711 769 + 0;
  • 3 711 769 ÷ 2 = 1 855 884 + 1;
  • 1 855 884 ÷ 2 = 927 942 + 0;
  • 927 942 ÷ 2 = 463 971 + 0;
  • 463 971 ÷ 2 = 231 985 + 1;
  • 231 985 ÷ 2 = 115 992 + 1;
  • 115 992 ÷ 2 = 57 996 + 0;
  • 57 996 ÷ 2 = 28 998 + 0;
  • 28 998 ÷ 2 = 14 499 + 0;
  • 14 499 ÷ 2 = 7 249 + 1;
  • 7 249 ÷ 2 = 3 624 + 1;
  • 3 624 ÷ 2 = 1 812 + 0;
  • 1 812 ÷ 2 = 906 + 0;
  • 906 ÷ 2 = 453 + 0;
  • 453 ÷ 2 = 226 + 1;
  • 226 ÷ 2 = 113 + 0;
  • 113 ÷ 2 = 56 + 1;
  • 56 ÷ 2 = 28 + 0;
  • 28 ÷ 2 = 14 + 0;
  • 14 ÷ 2 = 7 + 0;
  • 7 ÷ 2 = 3 + 1;
  • 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.

3 800 851 563(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 800 851 563 (base 10) = 1110 0010 1000 1100 0110 0100 0110 1011 (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)
