217370 ÷ 81 
Our goal is to divide 217370 by 81.

Let's proceed to 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
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

Step 2:
If we divide 21 by 81, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 81

Going ahead to step 3:
81 can be fit into 217 2 times, resulting in a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 162 from 217 to get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 81

Let's proceed to step 4:
If we divide 553 by 81, we get 6 and a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 486 from 553, we get 67.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 81

Moving on to step 5:
The number 81 fits into 677 8 times, leaving a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 268.0
If we take 648 away from 677, we end up with 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 81

Moving on to step 6:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 2683.0
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
470 divided by 81 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 2683.5
If we subtract 405 from 470, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
81 goes into 650 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 2683.58
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
20 divided by 81 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 2683.58
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
200 divided by 81 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 2683.5802
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
When dividing 380 by 81, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 2683.58024
Deduct 324 from 380 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
81 can be fit into 560 6 times, resulting in a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 2683.580246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
The number 81 fits into 740 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 2683.5802469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
When dividing 110 by 81, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 2683.58024691
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 2683.58024691 with a remaining 2.9e-08.
