218571 divided by 20 
We're looking to find how many times 20 goes into 218571.

On to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 20

Moving on to step 2:
20 goes into 21 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 20 from 21.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 20

Step 3:
20 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 20

Advancing to step 4:
20 can be fit into 185 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we subtract 180 from 185, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 20

On to step 5:
20 goes into 57 2 times with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 1092.0
Subtracting 40 from 57 leaves us with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 20

Let's proceed to step 6:
The number 20 fits into 171 8 times, leaving a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 10928.0
The remainder is 11 after subtracting 160 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 10928.5
Subtracting 100 from 110 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10928.55
The remainder is 0 after subtracting 100 from 100.
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 10928.55 and a remainder of 0.0.
