okay so you would just divide. you would see how many times 29 can fit into 73,205. for the first number it can fit twice so 73-58=15
so then how many times can 19 fit into 152 which is 5 times 152-145=7
then you would see how many times 29 fits in 70 which is 2 70-58=12
then you would see how many times 29 fits into 125 which is 4 125-116=9
then you would continue that until you get the answer which in the case would be 2524.310345
you get the answer by how many times the number can fit into the number you are given.
it might take a while but that is the best way without a calculator.
hope this helps!
