215406 ÷ 81 
We want to figure out the number of times 215406 can be divided by 81.

Advancing to step 1:
2 divided by 81 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 81

Advancing to step 2:
21 divided by 81 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 81

Let's proceed to step 3:
When dividing 215 by 81, we get 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 162 from 215 to get 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 81

Moving on to step 4:
When dividing 534 by 81, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 486 from 534 and we're left with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 81

Step 5:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 265.0
If we take 405 away from 480, we end up with 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 81

On to step 6:
81 goes into 756 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 2659.0
Subtracting 729 from 756 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 81 fits into 270 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 2659.3
If we take 243 away from 270, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
When dividing 270 by 81, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 2659.33
The remainder is 27 after subtracting 243 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 2659.33, and the remainder is 0.027.
