20217 ÷ 8 
We want to figure out the number of times 20217 can be divided by 8.

Step 1:
If we divide 2 by 8, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 8

On to step 2:
When dividing 20 by 8, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 16 from 20 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 8

Advancing to step 3:
8 can be fit into 42 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 40 from 42 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 8

Moving on to step 4:
21 divided by 8 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 252.0
The remainder is 5 after subtracting 16 from 21.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 8

On to step 5:
8 goes into 57 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 2527.0
The remainder is 1 after subtracting 56 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 6:
8 goes into 10 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 2527.1
The remainder is 2 after subtracting 8 from 10.
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 7:
20 divided by 8 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2527.12
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2527.125
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2527.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2527.125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2527.125 and a remainder of 0.0.
