We're dividing 216840 by 81 
We want to divide 216840 by 81.

Let's proceed to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 81

Let's proceed to step 2:
If we divide 21 by 81, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 81

Advancing to step 3:
When dividing 216 by 81, we get 2 with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 162 from 216, we get 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 81

On to step 4:
The number 81 fits into 548 6 times, leaving a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 62 after subtracting 486 from 548.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 81

Let's proceed to step 5:
The number 81 fits into 624 7 times, leaving a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
If we take 567 away from 624, we end up with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 81

Let's proceed to step 6:
If we divide 570 by 81, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2677.0
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 81 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2677.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
81 goes into 300 3 times with a remainder of 57.
The next digit of our result is 3. 
Result so far: 2677.03
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
When dividing 570 by 81, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2677.037
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
81 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2677.037
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
300 divided by 81 is 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 2677.03703
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
81 can be fit into 570 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 2677.037037
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2677.037037
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
300 divided by 81 is 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 2677.03703703
The remainder is 57 after subtracting 243 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 2677.03703703 with a remainder of 5.7e-08.
