What are the required steps to convert base 10 decimal system
number 2 146 468 065 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;
  • 2 146 468 065 ÷ 2 = 1 073 234 032 + 1;
  • 1 073 234 032 ÷ 2 = 536 617 016 + 0;
  • 536 617 016 ÷ 2 = 268 308 508 + 0;
  • 268 308 508 ÷ 2 = 134 154 254 + 0;
  • 134 154 254 ÷ 2 = 67 077 127 + 0;
  • 67 077 127 ÷ 2 = 33 538 563 + 1;
  • 33 538 563 ÷ 2 = 16 769 281 + 1;
  • 16 769 281 ÷ 2 = 8 384 640 + 1;
  • 8 384 640 ÷ 2 = 4 192 320 + 0;
  • 4 192 320 ÷ 2 = 2 096 160 + 0;
  • 2 096 160 ÷ 2 = 1 048 080 + 0;
  • 1 048 080 ÷ 2 = 524 040 + 0;
  • 524 040 ÷ 2 = 262 020 + 0;
  • 262 020 ÷ 2 = 131 010 + 0;
  • 131 010 ÷ 2 = 65 505 + 0;
  • 65 505 ÷ 2 = 32 752 + 1;
  • 32 752 ÷ 2 = 16 376 + 0;
  • 16 376 ÷ 2 = 8 188 + 0;
  • 8 188 ÷ 2 = 4 094 + 0;
  • 4 094 ÷ 2 = 2 047 + 0;
  • 2 047 ÷ 2 = 1 023 + 1;
  • 1 023 ÷ 2 = 511 + 1;
  • 511 ÷ 2 = 255 + 1;
  • 255 ÷ 2 = 127 + 1;
  • 127 ÷ 2 = 63 + 1;
  • 63 ÷ 2 = 31 + 1;
  • 31 ÷ 2 = 15 + 1;
  • 15 ÷ 2 = 7 + 1;
  • 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.

2 146 468 065(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 146 468 065 (base 10) = 111 1111 1111 0000 1000 0000 1110 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)
