What are the required steps to convert base 10 decimal system
number 3 735 928 965 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;
  • 3 735 928 965 ÷ 2 = 1 867 964 482 + 1;
  • 1 867 964 482 ÷ 2 = 933 982 241 + 0;
  • 933 982 241 ÷ 2 = 466 991 120 + 1;
  • 466 991 120 ÷ 2 = 233 495 560 + 0;
  • 233 495 560 ÷ 2 = 116 747 780 + 0;
  • 116 747 780 ÷ 2 = 58 373 890 + 0;
  • 58 373 890 ÷ 2 = 29 186 945 + 0;
  • 29 186 945 ÷ 2 = 14 593 472 + 1;
  • 14 593 472 ÷ 2 = 7 296 736 + 0;
  • 7 296 736 ÷ 2 = 3 648 368 + 0;
  • 3 648 368 ÷ 2 = 1 824 184 + 0;
  • 1 824 184 ÷ 2 = 912 092 + 0;
  • 912 092 ÷ 2 = 456 046 + 0;
  • 456 046 ÷ 2 = 228 023 + 0;
  • 228 023 ÷ 2 = 114 011 + 1;
  • 114 011 ÷ 2 = 57 005 + 1;
  • 57 005 ÷ 2 = 28 502 + 1;
  • 28 502 ÷ 2 = 14 251 + 0;
  • 14 251 ÷ 2 = 7 125 + 1;
  • 7 125 ÷ 2 = 3 562 + 1;
  • 3 562 ÷ 2 = 1 781 + 0;
  • 1 781 ÷ 2 = 890 + 1;
  • 890 ÷ 2 = 445 + 0;
  • 445 ÷ 2 = 222 + 1;
  • 222 ÷ 2 = 111 + 0;
  • 111 ÷ 2 = 55 + 1;
  • 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 number:

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

3 735 928 965(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 735 928 965 (base 10) = 1101 1110 1010 1101 1100 0000 1000 0101 (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)
