What are the required steps to convert base 10 decimal system
number 2 381 053 915 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;
  • 2 381 053 915 ÷ 2 = 1 190 526 957 + 1;
  • 1 190 526 957 ÷ 2 = 595 263 478 + 1;
  • 595 263 478 ÷ 2 = 297 631 739 + 0;
  • 297 631 739 ÷ 2 = 148 815 869 + 1;
  • 148 815 869 ÷ 2 = 74 407 934 + 1;
  • 74 407 934 ÷ 2 = 37 203 967 + 0;
  • 37 203 967 ÷ 2 = 18 601 983 + 1;
  • 18 601 983 ÷ 2 = 9 300 991 + 1;
  • 9 300 991 ÷ 2 = 4 650 495 + 1;
  • 4 650 495 ÷ 2 = 2 325 247 + 1;
  • 2 325 247 ÷ 2 = 1 162 623 + 1;
  • 1 162 623 ÷ 2 = 581 311 + 1;
  • 581 311 ÷ 2 = 290 655 + 1;
  • 290 655 ÷ 2 = 145 327 + 1;
  • 145 327 ÷ 2 = 72 663 + 1;
  • 72 663 ÷ 2 = 36 331 + 1;
  • 36 331 ÷ 2 = 18 165 + 1;
  • 18 165 ÷ 2 = 9 082 + 1;
  • 9 082 ÷ 2 = 4 541 + 0;
  • 4 541 ÷ 2 = 2 270 + 1;
  • 2 270 ÷ 2 = 1 135 + 0;
  • 1 135 ÷ 2 = 567 + 1;
  • 567 ÷ 2 = 283 + 1;
  • 283 ÷ 2 = 141 + 1;
  • 141 ÷ 2 = 70 + 1;
  • 70 ÷ 2 = 35 + 0;
  • 35 ÷ 2 = 17 + 1;
  • 17 ÷ 2 = 8 + 1;
  • 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.

2 381 053 915(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 381 053 915 (base 10) = 1000 1101 1110 1011 1111 1111 1101 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)
