We look at the division of 80983317 by 990 
Let's see how many times 990 fits into 80983317.

Step 1:
If we divide 8 by 990, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 990

Going ahead to step 2:
If we divide 80 by 990, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 990

Moving on to step 3:
990 goes into 809 0 times with a remainder of 809.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 809 to get 809.
Fetch the next digit (8) from the dividend, attach it to 809 and continue: 8098 / 990

On to step 4:
When dividing 8098 by 990, we get 8 with a remainder of 178.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7920 away from 8098, we end up with 178.
Grab the next digit (3) from the dividend, add it to 178, then carry on: 1783 / 990

Going ahead to step 5:
When dividing 1783 by 990, we get 1 with a remainder of 793.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 793 after subtracting 990 from 1783.
Include the next digit (3) from the dividend after 793, then repeat: 7933 / 990

Let's proceed to step 6:
7933 divided by 990 is 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 818.0
Subtract 7920 from 7933 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 990

On to step 7:
990 can be fit into 131 0 times, resulting in a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 8180.0
Subtracting 0 from 131 leaves us with 131.
Take the next digit (7) from the dividend and append it to 131, then repeat: 1317 / 990

Step 8:
The number 990 fits into 1317 1 times, leaving a remainder of 327.
Use 1 as the next digit of our solution. 
Result so far: 81801.0
Deduct 990 from 1317 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 9:
3270 divided by 990 is 3 with a remainder of 300.
Put 3 as the next digit of the answer. 
Result so far: 81801.3
Subtracting 2970 from 3270 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 10:
990 can be fit into 3000 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 81801.33
Subtracting 2970 from 3000 leaves us 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 81801.33, and the remainder is 0.03.
