85080 divided by 90 
Let's see how many times 90 fits into 85080.

On to step 1:
8 divided by 90 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 90

Step 2:
85 divided by 90 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 90

Going ahead to step 3:
The number 90 fits into 850 9 times, leaving a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 40 after subtracting 810 from 850.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 90

Going ahead to step 4:
If we divide 408 by 90, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 94.0
The remainder is 48 after subtracting 360 from 408.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 90

Step 5:
90 goes into 480 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 945.0
If we subtract 450 from 480, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 6:
The number 90 fits into 300 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 945.3
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
300 divided by 90 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 945.33
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 945.33, and the remainder is 0.03.
