What Is 1/42 as a Decimal + Solution With Free Steps

The fraction 1/42 as a decimal is equal to 0.023.

Decimal in arithmetic is a term that refers to a fraction in which the denominator has a power of ten, and the numerator has figures to be placed to the right of a decimal point. An example of a decimal is 9.87, clearing what a decimal is.

Here, we are more interested in the division types that result in a Decimal value, as this can be expressed as a Fraction. We see fractions as a way of showing two numbers having the operation of Division between them that result in a value that lies between two Integers.

Now, we introduce the method used to solve said fraction to decimal conversion, called Long Division, which we will discuss in detail moving forward. So, let’s go through the Solution of fraction 1/42.


First, we convert the fraction components, i.e., the numerator and the denominator, and transform them into the division constituents, i.e., the Dividend and the Divisor, respectively.

This can be done as follows:

Dividend = 1

Divisor = 42

Now, we introduce the most important quantity in our division process: the Quotient. The value represents the Solution to our division and can be expressed as having the following relationship with the Division constituents:

Quotient = Dividend $\div$ Divisor = 1 $\div$ 42

This is when we go through the Long Division solution to our problem.

We start solving a problem using the Long Division Method by first taking apart the division’s components and comparing them. As we have 1 and 42, we can see how 1 is Smaller than 42, and to solve this division, we require that 1 be Bigger than 42.

This is done by multiplying the dividend by 10 and checking whether it is bigger than the divisor or not. If so, we calculate the Multiple of the divisor closest to the dividend and subtract it from the Dividend. This produces the Remainder, which we then use as the dividend later.

Now, we begin solving for our dividend 1, which after getting multiplied by 100 becomes 100.

We take this 100 and divide it by 42; this can be done as follows:

 100 $\div$ 42 $\approx$ 2


42 x 2 = 84

This will lead to the generation of a Remainder equal to 100 – 84 = 16. Now this means we have to repeat the process by Converting the 16 into 160 and solving for that:

160 $\div$ 42 $\approx$ 3


42 x 3 = 126

This, therefore, produces another Remainder which is equal to 160– 126 = 34.

Finally, we have a Quotient generated after combining the three pieces of it as 0.023=z, with a Remainder equal to 340.
