How to use division in JavaScript

Make one of those numbers a float.

737/parseFloat(1070)

or a bit faster:

737*1.0/1070

convert to 2 decimal places

Math.round(737 * 100.0 / 1070) / 100

Also you can to use [.toPrecision(n)], where n is (total) the number of digits. So (23.467543).toPrecision(4) => 23.47 or (1241876.2341).toPrecision(8) => 1241876.2.

See MDN

Try this

 let ans = 737/1070;
 console.log(ans.toFixed(2));

toFixed() function will do

(737/1070).toFixed(2); rounds the result to 2 decimals and returns it as a string. In this case the rounded result is 0.69 by the way, not 0.68. If you need a real float rounded to 2 decimals from your division, use parseFloat((737/1070).toFixed(2))
