The number 520 fits into 693 1 times, leaving a remainder of 173.
Write down 1 as next digit of the result. 
Result so far: 28581.0
The remainder is 173 after subtracting 520 from 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 9:
520 goes into 1730 3 times with a remainder of 170.
The next digit of our result is 3. 
Result so far: 28581.3
Deduct 1560 from 1730 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
1700 divided by 520 is 3 with a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 28581.33
Deduct 1560 from 1700 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 28581.33, and the remainder is 0.14.
