53805 divided by 20 
We're looking to find how many times 20 goes into 53805.

Moving on to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 20

Moving on to step 2:
20 can be fit into 53 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 40 from 53 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 20

On to step 3:
The number 20 fits into 138 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 120 from 138 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

Advancing to step 4:
The number 20 fits into 180 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 269.0
Subtract 180 from 180 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 20

Let's proceed to step 5:
20 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 2690.0
Deduct 0 from 5 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.

Going ahead to step 6:
50 divided by 20 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2690.2
If we subtract 40 from 50, we 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 7:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2690.25
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.

Let's proceed to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2690.25
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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2690.25
Deduct 0 from 0 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.

The final result is 2690.25 with a remainder of 0.0.
