We're dividing 270388 by 20 
We want to figure out the number of times 270388 can be divided by 20.

Step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 20

Let's proceed to step 2:
27 divided by 20 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 27 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 20

Advancing to step 3:
20 goes into 70 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 10 after subtracting 60 from 70.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 20

Let's proceed to step 4:
If we divide 103 by 20, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Subtract 100 from 103 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 20

Going ahead to step 5:
If we divide 38 by 20, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1351.0
Subtracting 20 from 38 leaves us with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 20

Going ahead to step 6:
When dividing 188 by 20, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 13519.0
If we take 180 away from 188, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
20 can be fit into 80 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 13519.4
The remainder is 0 after subtracting 80 from 80.
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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13519.4
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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13519.4
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 final outcome is 13519.4, with a leftover of 0.0.
