What are the required steps to convert base 10 decimal system
number 6 227 020 781 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;
  • 6 227 020 781 ÷ 2 = 3 113 510 390 + 1;
  • 3 113 510 390 ÷ 2 = 1 556 755 195 + 0;
  • 1 556 755 195 ÷ 2 = 778 377 597 + 1;
  • 778 377 597 ÷ 2 = 389 188 798 + 1;
  • 389 188 798 ÷ 2 = 194 594 399 + 0;
  • 194 594 399 ÷ 2 = 97 297 199 + 1;
  • 97 297 199 ÷ 2 = 48 648 599 + 1;
  • 48 648 599 ÷ 2 = 24 324 299 + 1;
  • 24 324 299 ÷ 2 = 12 162 149 + 1;
  • 12 162 149 ÷ 2 = 6 081 074 + 1;
  • 6 081 074 ÷ 2 = 3 040 537 + 0;
  • 3 040 537 ÷ 2 = 1 520 268 + 1;
  • 1 520 268 ÷ 2 = 760 134 + 0;
  • 760 134 ÷ 2 = 380 067 + 0;
  • 380 067 ÷ 2 = 190 033 + 1;
  • 190 033 ÷ 2 = 95 016 + 1;
  • 95 016 ÷ 2 = 47 508 + 0;
  • 47 508 ÷ 2 = 23 754 + 0;
  • 23 754 ÷ 2 = 11 877 + 0;
  • 11 877 ÷ 2 = 5 938 + 1;
  • 5 938 ÷ 2 = 2 969 + 0;
  • 2 969 ÷ 2 = 1 484 + 1;
  • 1 484 ÷ 2 = 742 + 0;
  • 742 ÷ 2 = 371 + 0;
  • 371 ÷ 2 = 185 + 1;
  • 185 ÷ 2 = 92 + 1;
  • 92 ÷ 2 = 46 + 0;
  • 46 ÷ 2 = 23 + 0;
  • 23 ÷ 2 = 11 + 1;
  • 11 ÷ 2 = 5 + 1;
  • 5 ÷ 2 = 2 + 1;
  • 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.

6 227 020 781(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

6 227 020 781 (base 10) = 1 0111 0011 0010 1000 1100 1011 1110 1101 (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)
