Let's divide 211531 by 20
Our goal is to divide 211531 by 20.

Let's proceed to step 1:
2 divided by 20 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 20

Going ahead to step 2:
If we divide 21 by 20, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 20 from 21 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 20

On to step 3:
20 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 11 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 20

Moving on to step 4:
115 divided by 20 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 105.0
The remainder is 15 after subtracting 100 from 115.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 20

Advancing to step 5:
20 goes into 153 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 1057.0
If we subtract 140 from 153, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 20

Advancing to step 6:
If we divide 131 by 20, we get 6 and a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 10576.0
Subtracting 120 from 131 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10576.5
Subtract 100 from 110 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10576.55
Deduct 100 from 100 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.

Our division results in 10576.55 with a remaining 0.0.
