# Thread: Divisions With "big" Numbers

1. ## Divisions With "big" Numbers

Ok... They're not big numbers.

--

Is there a proper method to do these divisions without a calculator?

1104/48 = 23

To do that sum, I would multiply 48 by 10 to get 480 and then double it to get 960. I would then keep subtracting 48 from 144 (1104 - 960) until I get 0. Is there a proper way of doing this?

Thanks.

Try here: Long Division

for an excellent explanation.

hi
To divide 1104/48
First u have to see the first three digits out of four digits ok
here the number is 1104 right
in that take 110
then u have to recite the multiple of 48 ok
48*1=48,48*2=96,48*3=144 -Here u have to compare the answer with the multiples of 48
110 is given in the problem
less than 110 is 96 which is the multiple of 48*2
The remainder is 14 there the fourth digit given in the problem is 4 - so 144
then 48*3=144 we know
Hence the answer u got 1104/48 =23
I think that u may understood now

One way is by cancellation in reducing the original fraction into its simplest form.

1104 / 48.
1104 and 48 are divisible by 2. So cancell the 2 from both,
= 552 / 24

552 and 24 are again each divisible by 2. Cancell again 2 from each,
= 276 / 12

Again, cancel 2 from 276 and 12,
= 138 / 6

Again,
= 69 / 3

Finally,
= 23.
