We're dividing 99830 by 80 
We want to figure out the number of times 99830 can be divided by 80.

Let's proceed to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 80

Step 2:
80 goes into 99 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 80 from 99 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 80

On to step 3:
When dividing 198 by 80, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 160 from 198 leaves us with 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 80

Step 4:
The number 80 fits into 383 4 times, leaving a remainder of 63.
The next digit of our result is 4. 
Result so far: 124.0
The remainder is 63 after subtracting 320 from 383.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 80

Let's proceed to step 5:
630 divided by 80 is 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 1247.0
Subtract 560 from 630 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 6:
700 divided by 80 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 1247.8
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
80 goes into 600 7 times with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1247.87
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1247.875
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1247.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1247.875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1247.875 and a remainder of 0.0.
