You will need to be able to do some form of long division to get the answer; but first let’s do something about the decimal point.
5050.21/0.7959=50502.1/7.959=505021/79.59=...=50502100/7959.
All these fractions are the same so we use the last one because it has no decimal points in the divisor.
Let’s also do an estimate of the answer: 50000000/8000=50000/8=6000 approx. So we expect the quotient to be round about 6000.
6345.28...
7959 ) 50502100.00...
-47754
27481
-23877
36040
-31836
42040
-39795
22450
-15918
65320 etc.
See how the decimal points in the quotient and dividend line up. We estimated the answer was going to be around 6000, so 6345.28 seems to be correct as far as we’ve taken it. We can be confident that the decimal point is in the right place.
