Let's divide 198009 by 80
We're looking to find how many times 80 goes into 198009.

Let's proceed to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 80

Let's proceed to step 2:
80 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 80

Going ahead to step 3:
80 can be fit into 198 2 times, resulting in a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 160 from 198 leaves us with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 80

Going ahead to step 4:
80 can be fit into 380 4 times, resulting in a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 320 from 380 and we're left with 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 80

Advancing to step 5:
If we divide 600 by 80, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 247.0
The remainder is 40 after subtracting 560 from 600.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 80

Step 6:
80 can be fit into 409 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 2475.0
The remainder is 9 after subtracting 400 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
80 can be fit into 90 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 2475.1
Deduct 80 from 90 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 2475.11
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 2475.11, and the remainder is 0.02.
