215635 ÷ 20 
Our goal is to divide 215635 by 20.

Going ahead 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
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 20

Step 2:
20 can be fit into 21 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 20 from 21 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

On to step 3:
If we divide 15 by 20, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 20

Moving on to step 4:
If we divide 156 by 20, we get 7 and a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 140 away from 156, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 20

Advancing to step 5:
20 can be fit into 163 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 1078.0
Deduct 160 from 163 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Let's proceed to step 6:
20 can be fit into 35 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 10781.0
Deduct 20 from 35 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
20 can be fit into 150 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 10781.7
Deduct 140 from 150 and we're left 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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10781.75
If we take 100 away from 100, we end up 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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10781.75
Subtracting 0 from 0 leaves us 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.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10781.75
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 10781.75, and the remainder is 0.0.
