270229 ÷ 21 
Our goal is to divide 270229 by 21.

On to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 21

Moving on to step 2:
21 can be fit into 27 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 6 after subtracting 21 from 27.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 21

Moving on to step 3:
When dividing 60 by 21, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 42 from 60, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 21

Advancing to step 4:
The number 21 fits into 182 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 168 from 182 leaves us with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 21

Step 5:
When dividing 142 by 21, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1286.0
If we take 126 away from 142, we end up with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 21

Let's proceed to step 6:
When dividing 169 by 21, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 12868.0
If we subtract 168 from 169, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12868.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
21 goes into 100 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 12868.04
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 12868.047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 12868.0476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 12868.04761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 12868.047619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12868.047619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
If we divide 100 by 21, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 12868.04761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 12868.04761904 and a remainder of 1.6e-08.
