216985 ÷ 81 
Our goal is to divide 216985 by 81.

Step 1:
If we divide 2 by 81, we get 0 and 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 81

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.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 81

Advancing to step 3:
81 goes into 216 2 times with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 162 away from 216, we end up with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 81

Advancing to step 4:
81 goes into 549 6 times with a remainder of 63.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 486 from 549 to get 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 81

Let's proceed to step 5:
81 goes into 638 7 times with a remainder of 71.
The next digit of our result is 7. 
Result so far: 267.0
Subtract 567 from 638 to get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 81

Going ahead to step 6:
81 goes into 715 8 times with a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 2678.0
If we take 648 away from 715, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
When dividing 670 by 81, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2678.8
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
81 goes into 220 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 2678.82
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
When dividing 580 by 81, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 2678.827
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
130 divided by 81 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 2678.8271
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
490 divided by 81 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2678.82716
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
81 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2678.82716
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 81, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 2678.8271604
The remainder is 76 after subtracting 324 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
81 goes into 760 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 2678.82716049
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 2678.82716049, and the remainder is 3.1e-08.
