I am looking for a citation from winston churchill. The gist of what
he said was:
Sometimes you have to make a big step because you canīt cross a wide
gap making two little steps.

Hello dho-ga

This saying is in fact attributed to David Lloyd George (1863-1945),
who was a British Liberal MP for 50 years, Chancellor of the Exchequer
during 1908-1915 and Prime Minister during 1916-1922.

The most frequent form of the quotation as given is:

Don't be afraid to take a big step if one is indicated; you can't
cross a chasm in two small jumps."

For example at http://www.quoteworld.org/browse.php?thetext=fear,afraid,terror,scare&page=13
http://www.teal.org.uk/Leadership/quotes.htm
And, also according to the Canadian Conservative Forum
http://www.conservativeforum.org/authquot.asp?ID=952 which gives the
infromation that these words were said in a speech given in December
1910 (ie around the time of the General Election)

In his Nobel Lecture given on December 11, 1959, Philip Noel-Baker
gives an alternative version: "The most dangerous thing in the world
is to try to leap a chasm in two jumps” and also attributes it to
Lloyd George but with no information on the exact source.

Unfortunately, there is currently no online archive of Lloyd George
against which to check further, although his political papers will
feature in the planned Archives Network Wales

Search strategy:  I tried variations of words from the quotation as
originally given, and found it using: “big step” and “cross” as search
terms.
