What are the required steps to convert base 10 decimal system
number 2 571 108 145 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;
  • 2 571 108 145 ÷ 2 = 1 285 554 072 + 1;
  • 1 285 554 072 ÷ 2 = 642 777 036 + 0;
  • 642 777 036 ÷ 2 = 321 388 518 + 0;
  • 321 388 518 ÷ 2 = 160 694 259 + 0;
  • 160 694 259 ÷ 2 = 80 347 129 + 1;
  • 80 347 129 ÷ 2 = 40 173 564 + 1;
  • 40 173 564 ÷ 2 = 20 086 782 + 0;
  • 20 086 782 ÷ 2 = 10 043 391 + 0;
  • 10 043 391 ÷ 2 = 5 021 695 + 1;
  • 5 021 695 ÷ 2 = 2 510 847 + 1;
  • 2 510 847 ÷ 2 = 1 255 423 + 1;
  • 1 255 423 ÷ 2 = 627 711 + 1;
  • 627 711 ÷ 2 = 313 855 + 1;
  • 313 855 ÷ 2 = 156 927 + 1;
  • 156 927 ÷ 2 = 78 463 + 1;
  • 78 463 ÷ 2 = 39 231 + 1;
  • 39 231 ÷ 2 = 19 615 + 1;
  • 19 615 ÷ 2 = 9 807 + 1;
  • 9 807 ÷ 2 = 4 903 + 1;
  • 4 903 ÷ 2 = 2 451 + 1;
  • 2 451 ÷ 2 = 1 225 + 1;
  • 1 225 ÷ 2 = 612 + 1;
  • 612 ÷ 2 = 306 + 0;
  • 306 ÷ 2 = 153 + 0;
  • 153 ÷ 2 = 76 + 1;
  • 76 ÷ 2 = 38 + 0;
  • 38 ÷ 2 = 19 + 0;
  • 19 ÷ 2 = 9 + 1;
  • 9 ÷ 2 = 4 + 1;
  • 4 ÷ 2 = 2 + 0;
  • 2 ÷ 2 = 1 + 0;
  • 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.

2 571 108 145(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 571 108 145 (base 10) = 1001 1001 0011 1111 1111 1111 0011 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)
