We're dividing 253162 by 20 
We want to figure out the number of times 253162 can be divided by 20.

On to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 20

On to step 2:
25 divided by 20 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 20 from 25 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 20

Moving on to step 3:
If we divide 53 by 20, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 40 from 53, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 20

Going ahead to step 4:
The number 20 fits into 131 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 126.0
If we take 120 away from 131, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 20

Step 5:
20 can be fit into 116 5 times, resulting in a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 1265.0
If we subtract 100 from 116, we get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 20

Let's proceed to step 6:
20 goes into 162 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 12658.0
If we subtract 160 from 162, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 can be fit into 20 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 12658.1
Deduct 20 from 20 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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12658.1
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12658.1
Subtract 0 from 0 to get 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 outcome is 12658.1, with a leftover of 0.0.
