We look at the division of 21712 by 20 
Let's see how many times 20 fits into 21712.

Let's proceed to step 1:
20 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 20

Let's proceed to step 2:
21 divided by 20 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 20 from 21 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 20

Advancing to step 3:
The number 20 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 20

Moving on to step 4:
If we divide 171 by 20, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtract 160 from 171 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 20

On to step 5:
If we divide 112 by 20, we get 5 and a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 1085.0
Subtract 100 from 112 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 6:
20 goes into 120 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1085.6
The remainder is 0 after subtracting 120 from 120.
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 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1085.6
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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1085.6
Subtract 0 from 0 to get 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 1085.6 and a remainder of 0.0.
