Try this. It's similar to Boris' solution - also from my Iban

Since the precision of double is about 15.95 digits - 15 to be safe - it calculates how many digits (for/next/step) it can take per calculation

In the case of mod 97 that would be steps of 13

*--------------------------------------------------------------------------
function Do_it()
	
	?Mod_String('2291909071000729000', 97)
	
endfunc
*--------------------------------------------------------------------------
function Mod_String(s, Divisor)

	local StepSize, StepMultiplier, i, n
	
	StepSize = (15 - ceiling(log10(m.Divisor)))
	StepMultiplier = int(10 ^ m.StepSize)
	
	n = 0
	
	for i = 1 to len(m.s) step m.StepSize 
		n = mod(int(m.n * m.StepMultiplier) + int(val(substr(m.s, m.i, m.StepSize))), m.Divisor)
	endfor
	
	return m.n
endfunc
