16 goes into 160 : 10 times leaving remainder of 90
16 goes into 90 :5 times leaving remainder of 10
1.6 goes into 10 6 times leaving reminder of 0.4
0.16 goes into 0.4 :2 times leaving remainder of 0.08
0.916 gues into 0.08 :5 times with no remainder
Alternatively (how I did it in my head):
Divide both by 2 to give an eighth of 125
Knowing 120 is going to be divisible by 8 gives 5/8th remainder
120 divided by 8 = 60 divide by 4 = 30 divided by 2 = 15
so answer 15 5/8ths
an eighth is 0.125 so multiply by 5 to give 0.625
looks long and difficult, but took 20 times as long to work out how I did it than to do it.
If you are feeling really lazy type 1/16 * 250 into google and get 15.625.
Just "1/16 of 250" will do. However it doesn't like "1/16th of 250".
Whether the OP will understand the answer, with 3 decimal places, is another matter. (It will likely be presented to a greater accuracy than the numbers used to work it out.)
I know I haven't been to school for almost 40 years, but this is the sort of thing most 12 year olds should be able to do easily. Has understanding of simple arithmetic really plummeted so much?

Because it is! (Especially given that the OP seems to be struggling with the concept of fractions and division!)
Just halve 250, and repeat 3 more times.
(You will get 125, 62.5, 31.25, 15.625. If even that is too hard, use a ruler, pen and scissors. Cut a strip 250mm long. Fold it in half lengthways four times. Measure the result, it should be about 16mm; not quite as accurate, but then we don't know the 250 or 1/16 were that accurate either.)

I pray to all dieties almighty I hope you are taking the rising piss.
Calculator, phone, even a ****ing abacus can work this out. 250 divided by 16.
My initial thought would be what is the answer going to be used for? For example, if it is to split a restaurant bill to give a per head sum including a fair tip, I wouldn't be looking at being so precise with any answer.

I was showing alternative and IMO simpler ways of dividing by 16, if you weren't just going to give up on arithmetic and rely on a machine to do even the simplest task

Using a calculator or phone is a bit of a cop-out (and I'm sure even the OP can sort that out that part once he knows what calculation to do.)
But I would be interested in how you'd use an abacus to do this...

Your answer is 15.625 litres.
16 goes into 160 : 10 times leaving remainder of 90
16 goes into 90 :5 times leaving remainder of 10
1.6 goes into 10 6 times leaving reminder of 0.4
0.16 goes into 0.4 :2 times leaving remainder of 0.08
0.916 gues into 0.08 :5 times with no remainder
So the answer is 15.625
Divide both by 2 to give an eighth of 125
Knowing 120 is going to be divisible by 8 gives 5/8th remainder
120 divided by 8 = 60 divide by 4 = 30 divided by 2 = 15
so answer 15 5/8ths
an eighth is 0.125 so multiply by 5 to give 0.625
looks long and difficult, but took 20 times as long to work out how I did it than to do it.
If you have to work out a fraction a/b of a number c
Multiply c by a then divide the result by b
So 3/5 of 100 is
3x100 = 300, 300/5 = 60
Or in the OP
1/16 of 250
250x1 = 250, 250/16 = 15.625
Or if you're feeling even lazier, just type in 250/16.
Ah yes but the OP did type ...
I know....I don't quite understand your point.
Simply dividing something by 16 is the same as multiplying it by one-sixteenth. And a lot easier.
The answer, as mentioned many times above is indeed 15.625 litres, however, if presented with the question in that format I would respond with
15 5/8 (Fifteen and five eighths)
Then divide by 1000 to give 64/1000
Then divide by 8 to give 8/125, which is the smallest fraction.
Just "1/16 of 250" will do. However it doesn't like "1/16th of 250".
Whether the OP will understand the answer, with 3 decimal places, is another matter. (It will likely be presented to a greater accuracy than the numbers used to work it out.)
Simply divide 250 by 16 to get 15.625 as everyone else has said.
However, are you trying to convert an imperial measure into a metric measure?
Because it is! (Especially given that the OP seems to be struggling with the concept of fractions and division!)
Just halve 250, and repeat 3 more times.
