We look at the division of 211817 by 81 
Our goal is to divide 211817 by 81.

Let's proceed to step 1:
2 divided by 81 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 81

Advancing to step 2:
81 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 81

On to step 3:
211 divided by 81 is 2 with a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 49 after subtracting 162 from 211.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 81

Advancing to step 4:
498 divided by 81 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 486 from 498 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 81

Step 5:
81 can be fit into 121 1 times, resulting in a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 261.0
If we subtract 81 from 121, we get 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 81

On to step 6:
When dividing 407 by 81, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 2615.0
Subtract 405 from 407 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 81 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2615.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
81 can be fit into 200 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2615.02
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
81 goes into 380 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 2615.024
If we take 324 away from 380, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
81 goes into 560 6 times with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 2615.0246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 11:
When dividing 740 by 81, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 2615.02469
The remainder is 11 after subtracting 729 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
110 divided by 81 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 2615.024691
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
290 divided by 81 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 2615.0246913
Subtract 243 from 290 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
81 goes into 470 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 2615.02469135
If we subtract 405 from 470, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 2615.02469135 and a remainder of 6.5e-08.
