We're dividing 216315 by 81 
Let's see how many times 81 fits into 216315.

Advancing to step 1:
81 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 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.
Write down 0 as next digit of 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

Let's proceed to step 3:
The number 81 fits into 216 2 times, leaving a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 162 from 216 to get 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 81

Moving on to step 4:
When dividing 543 by 81, we get 6 with a remainder of 57.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 486 from 543 leaves us with 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 81

Advancing to step 5:
When dividing 571 by 81, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 267.0
Subtract 567 from 571 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 81

Advancing to step 6:
45 divided by 81 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 2670.0
If we take 0 away from 45, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
450 divided by 81 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2670.5
If we subtract 405 from 450, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
When dividing 450 by 81, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 2670.55
Deduct 405 from 450 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 2670.55 with a balance of 0.045.
