217821 divided by 80 
We're looking to find how many times 80 goes into 217821.

On to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 80

Advancing to step 2:
80 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 80

Let's proceed to step 3:
If we divide 217 by 80, we get 2 and a remainder of 57.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 160 from 217 leaves us with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 80

Step 4:
578 divided by 80 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 18 after subtracting 560 from 578.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 80

Advancing to step 5:
When dividing 182 by 80, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 272.0
If we take 160 away from 182, we end up with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 80

Step 6:
80 can be fit into 221 2 times, resulting in a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 2722.0
The remainder is 61 after subtracting 160 from 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
When dividing 610 by 80, we get 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 2722.7
Subtract 560 from 610 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
500 divided by 80 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 2722.76
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 2722.762
Deduct 160 from 200 and we're left 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.

Step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2722.7625
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.

Going ahead to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2722.7625
If we take 0 away from 0, 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.

Let's proceed to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2722.7625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2722.7625 with a balance of 0.0.
