Step 1: The exponent for 10 is -26. Since the exponent is negative, we must move the decimal point of a number 1.75 26 places to the left.
1.75 → .-------------------------1.75
Step 2: Now we just need to replace empty spaces (dashes) with zeros and to delete old decimal point (the black one) to get:
.0000000000000000000000000175
