We're dividing 227178 by 21 
Our goal is to divide 227178 by 21.

Let's proceed to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

Moving on to step 2:
If we divide 22 by 21, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 21 from 22 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 21

Going ahead to step 3:
The number 21 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 17, we get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 21

On to step 4:
21 can be fit into 171 8 times, resulting in a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 108.0
The remainder is 3 after subtracting 168 from 171.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 21

Moving on to step 5:
If we divide 37 by 21, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 1081.0
If we subtract 21 from 37, we get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 21

Step 6:
21 can be fit into 168 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 10818.0
The remainder is 0 after subtracting 168 from 168.
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 7:
If we divide 0 by 21, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10818.0
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.

Let's proceed to step 8:
0 divided by 21 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10818.0
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 result is 10818.0 with a remainder of 0.0.
