We look at the division of 215404 by 81 
Our goal is to divide 215404 by 81.

On to step 1:
2 divided by 81 is 0 with a remainder of 2.
The next digit of our result is 0. 
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

On to step 2:
81 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 81

Moving on to step 3:
When dividing 215 by 81, we get 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 162 from 215 and we're left with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 81

Moving on to step 4:
If we divide 534 by 81, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 486 away from 534, we end up with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 81

Moving on to step 5:
When dividing 480 by 81, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Subtracting 405 from 480 leaves us with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 81

On to step 6:
If we divide 754 by 81, we get 9 and a remainder of 25.
The next digit of our result is 9. 
Result so far: 2659.0
The remainder is 25 after subtracting 729 from 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
When dividing 250 by 81, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 2659.3
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 2659.3
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 2659.308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 2659.3086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 2659.30864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
160 divided by 81 is 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 2659.308641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 13:
81 goes into 790 9 times with a remainder of 61.
The next digit of our result is 9. 
Result so far: 2659.3086419
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 14:
When dividing 610 by 81, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 2659.30864197
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 2659.30864197, and the remainder is 4.3e-08.
