Let's divide 199842 by 80
We want to divide 199842 by 80.

Going ahead to step 1:
80 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 80

Let's proceed to step 2:
When dividing 19 by 80, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 80

Let's proceed to step 3:
When dividing 199 by 80, we get 2 with a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 39 after subtracting 160 from 199.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 80

Advancing to step 4:
80 goes into 398 4 times with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 320 from 398 to get 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 80

Advancing to step 5:
If we divide 784 by 80, we get 9 and a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 249.0
The remainder is 64 after subtracting 720 from 784.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 80

Moving on to step 6:
The number 80 fits into 642 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2498.0
Deduct 640 from 642 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 80, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2498.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 2498.02
If we take 160 away from 200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 2498.025
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2498.025
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.

Going ahead to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2498.025
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.

The quotient of the division is 2498.025, and the remainder is 0.0.
