Find it hard to do long division $10000 /0.08$
$begingroup$
Sorry if this is very basic! But I can't seem to do something like
$10000 /0.08$, without a calculator. How would one go about solving this without a calculator?

Multiply both the numerator and denominator by $100$ to get $1000000/8$, then divide.

Observe that $0.08 = frac {8} {100}.$ So we have $$frac {10000} {0.08} = frac {10000 times 100} {8}.$$ Can you proceed now?

Firstly: Dividing by $8$ is three times dividing by $2$. Consequently, $1000:2=500$, $1000:4=(1000:2):2)=500:2=250$ and $$1000:8=((1000:2):2):2=(500:2):2=250:2=125.$$ Secondly, learn these quotients by heart: every humanistically educated human being should know how much a half, a quarter and an eighth of $1000$ is. As well as that a day has $86400$ seconds ...

Just make some transformations:
$0.08=frac8{100}$. Therefore the term becomes $frac{10000}{frac8{100}}$
Then:
Dividing a term by a fraction is the same as multiplying the term by the
reciprocal of the fraction.
That means $10000cdot frac{100}8=frac{10000}{8}cdot 100=1250cdot 100=125,000$.

We know that $0.08=frac{8}{100}$, so $frac{1}{0.08} = frac{100}{8}$ we can do this as one divided by a fraction can be just flipped to remove the divided "bit".
So $$frac{10000}{0.08}=frac{100 * 10000}{8}$$
Then $8$ goes into $10000$, $1250$ times so $frac{10000}{0.08}=1250*100= 125000$

You can write $$frac{10000cdot 100}{8}$$

You could turn 0.08 to a fraction, take recipricol, then multiply that by 10000 which is a lot easier imo. If you don't want to do the weird decimal movement thing.
