Advancing to step 11:
902 goes into 1640 1 times with a remainder of 738.
Put 1 as the next digit of the answer. 
Result so far: 80537.681
If we take 902 away from 1640, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Moving on to step 12:
7380 divided by 902 is 8 with a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 80537.6818
If we subtract 7216 from 7380, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

1640 divided by 902 is 1 with a remainder of 738.
Put 1 as the next digit of the answer. 
Result so far: 80537.68181
Subtract 902 from 1640 to get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Let's proceed to step 14:
When dividing 7380 by 902, we get 8 with a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 80537.681818
Subtract 7216 from 7380 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 15:
When dividing 1640 by 902, we get 1 with a remainder of 738.
Record the quotient 1 as the next digit in the result. 
Result so far: 80537.6818181
If we take 902 away from 1640, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

On to step 16:
7380 divided by 902 is 8 with a remainder of 164.
Write down 8 as next digit of the result.
