As John said, thirty five billion eight hundred six million four hundred eighty six thousand two hundred twenty six in numerical form is 35, 806, 486, 226. If you're struggling to write out large numbers in numerical form, you can do this by taking a step-by-step approach.

With a large number, it is often easier to start with the smallest number first and work way way 'upwards'.

6 - six

26 - twenty-six

226 - two hundred and twenty-six

6, 226 -

six thousand, two hundred and twenty-six

86, 226 - eighty six thousand, two hundred and twenty-six

486, 226 - four hundred and eighty six thousand, two hundred and twenty-six

6, 486, 226 - six million, four hundred and eighty six thousand, two hundred and twenty-six

there is no figure in the ten millions column (zero doesn't count in this instance), so we move onto:

806, 486, 266 - eight hundred and six million, four hundred and eighty six thousand, two hundred and twenty-six

5, 806, 486, 266 - five billion, eight hundred and six million, four hundred and eighty six thousand, two hundred and twenty-six

35, 806, 486, 226 - thirty-five billion, eight hundred and six million, four hundred and eighty six thousand, two hundred and twenty-six.
