We divide 216815 by 81
We want to divide 216815 by 81.

Step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 81

Moving on to step 2:
21 divided by 81 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 81

Going ahead to step 3:
When dividing 216 by 81, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 162 away from 216, we end up with 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 81

On to step 4:
When dividing 548 by 81, we get 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 486 away from 548, we end up with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 81

Moving on to step 5:
81 can be fit into 621 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 267.0
Subtract 567 from 621 to get 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 81

On to step 6:
The number 81 fits into 545 6 times, leaving a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 2676.0
Subtract 486 from 545 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
81 can be fit into 590 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 2676.7
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
81 goes into 230 2 times with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 2676.72
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
680 divided by 81 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 2676.728
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
320 divided by 81 is 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 2676.7283
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 11:
770 divided by 81 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 2676.72839
If we take 729 away from 770, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 12:
When dividing 410 by 81, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2676.728395
Deduct 405 from 410 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
When dividing 50 by 81, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 2676.728395
If we subtract 0 from 50, we 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.

On to step 14:
The number 81 fits into 500 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 2676.72839506
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 2676.72839506 and a remainder of 1.4e-08.
