20835 ÷ 53 
We want to figure out the number of times 20835 can be divided by 53.

Advancing to step 1:
2 divided by 53 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 53

Let's proceed to step 2:
20 divided by 53 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 53

Let's proceed to step 3:
53 goes into 208 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 49 after subtracting 159 from 208.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 53

Step 4:
53 goes into 493 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 477 from 493 leaves us with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 53

Advancing to step 5:
If we divide 165 by 53, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 393.0
If we subtract 159 from 165, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 6:
53 can be fit into 60 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 393.1
The remainder is 7 after subtracting 53 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 53 fits into 70 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 393.11
If we subtract 53 from 70, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 393.11 with a remainder of 0.017.
