What are the required steps to convert base 10 decimal system
number 2 147 412 591 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;
  • 2 147 412 591 ÷ 2 = 1 073 706 295 + 1;
  • 1 073 706 295 ÷ 2 = 536 853 147 + 1;
  • 536 853 147 ÷ 2 = 268 426 573 + 1;
  • 268 426 573 ÷ 2 = 134 213 286 + 1;
  • 134 213 286 ÷ 2 = 67 106 643 + 0;
  • 67 106 643 ÷ 2 = 33 553 321 + 1;
  • 33 553 321 ÷ 2 = 16 776 660 + 1;
  • 16 776 660 ÷ 2 = 8 388 330 + 0;
  • 8 388 330 ÷ 2 = 4 194 165 + 0;
  • 4 194 165 ÷ 2 = 2 097 082 + 1;
  • 2 097 082 ÷ 2 = 1 048 541 + 0;
  • 1 048 541 ÷ 2 = 524 270 + 1;
  • 524 270 ÷ 2 = 262 135 + 0;
  • 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.

2 147 412 591(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 147 412 591 (base 10) = 111 1111 1111 1110 1110 1010 0110 1111 (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)
