205165 divided by 20 
We're looking to find how many times 20 goes into 205165.

Step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 20

Step 2:
If we divide 20 by 20, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 20 from 20.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 20

On to step 3:
If we divide 5 by 20, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 20

Going ahead to step 4:
The number 20 fits into 51 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Deduct 40 from 51 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 20

Step 5:
20 goes into 116 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 1025.0
If we subtract 100 from 116, we get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 20

Moving on to step 6:
If we divide 165 by 20, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 10258.0
Deduct 160 from 165 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 20, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 10258.2
If we take 40 away from 50, we end up 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.

Let's proceed to step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10258.25
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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10258.25
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.

Going ahead to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10258.25
If we take 0 away from 0, 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.

The quotient of the division is 10258.25, and the remainder is 0.0.
