What are the required steps to convert base 10 decimal system
number 2 147 416 971 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;
  • 2 147 416 971 ÷ 2 = 1 073 708 485 + 1;
  • 1 073 708 485 ÷ 2 = 536 854 242 + 1;
  • 536 854 242 ÷ 2 = 268 427 121 + 0;
  • 268 427 121 ÷ 2 = 134 213 560 + 1;
  • 134 213 560 ÷ 2 = 67 106 780 + 0;
  • 67 106 780 ÷ 2 = 33 553 390 + 0;
  • 33 553 390 ÷ 2 = 16 776 695 + 0;
  • 16 776 695 ÷ 2 = 8 388 347 + 1;
  • 8 388 347 ÷ 2 = 4 194 173 + 1;
  • 4 194 173 ÷ 2 = 2 097 086 + 1;
  • 2 097 086 ÷ 2 = 1 048 543 + 0;
  • 1 048 543 ÷ 2 = 524 271 + 1;
  • 524 271 ÷ 2 = 262 135 + 1;
  • 262 135 ÷ 2 = 131 067 + 1;
  • 131 067 ÷ 2 = 65 533 + 1;
  • 65 533 ÷ 2 = 32 766 + 1;
  • 32 766 ÷ 2 = 16 383 + 0;
  • 16 383 ÷ 2 = 8 191 + 1;
  • 8 191 ÷ 2 = 4 095 + 1;
  • 4 095 ÷ 2 = 2 047 + 1;
  • 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.

2 147 416 971(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 147 416 971 (base 10) = 111 1111 1111 1110 1111 1011 1000 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)
