If we take 558 away from 690, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
When dividing 1320 by 279, we get 4 with a remainder of 204.
Use 4 as the next digit of our solution. 
Result so far: 290663.98924
The remainder is 204 after subtracting 1116 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 14:
279 can be fit into 2040 7 times, resulting in a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 290663.989247
Deduct 1953 from 2040 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 15:
The number 279 fits into 870 3 times, leaving a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 290663.9892473
