What are the required steps to convert base 10 decimal system
number 2 147 941 787 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;
  • 2 147 941 787 ÷ 2 = 1 073 970 893 + 1;
  • 1 073 970 893 ÷ 2 = 536 985 446 + 1;
  • 536 985 446 ÷ 2 = 268 492 723 + 0;
  • 268 492 723 ÷ 2 = 134 246 361 + 1;
  • 134 246 361 ÷ 2 = 67 123 180 + 1;
  • 67 123 180 ÷ 2 = 33 561 590 + 0;
  • 33 561 590 ÷ 2 = 16 780 795 + 0;
  • 16 780 795 ÷ 2 = 8 390 397 + 1;
  • 8 390 397 ÷ 2 = 4 195 198 + 1;
  • 4 195 198 ÷ 2 = 2 097 599 + 0;
  • 2 097 599 ÷ 2 = 1 048 799 + 1;
  • 1 048 799 ÷ 2 = 524 399 + 1;
  • 524 399 ÷ 2 = 262 199 + 1;
  • 262 199 ÷ 2 = 131 099 + 1;
  • 131 099 ÷ 2 = 65 549 + 1;
  • 65 549 ÷ 2 = 32 774 + 1;
  • 32 774 ÷ 2 = 16 387 + 0;
  • 16 387 ÷ 2 = 8 193 + 1;
  • 8 193 ÷ 2 = 4 096 + 1;
  • 4 096 ÷ 2 = 2 048 + 0;
  • 2 048 ÷ 2 = 1 024 + 0;
  • 1 024 ÷ 2 = 512 + 0;
  • 512 ÷ 2 = 256 + 0;
  • 256 ÷ 2 = 128 + 0;
  • 128 ÷ 2 = 64 + 0;
  • 64 ÷ 2 = 32 + 0;
  • 32 ÷ 2 = 16 + 0;
  • 16 ÷ 2 = 8 + 0;
  • 8 ÷ 2 = 4 + 0;
  • 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.

2 147 941 787(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 147 941 787 (base 10) = 1000 0000 0000 0110 1111 1101 1001 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)
