If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 14

Moving on to step 2:
The number 14 fits into 21 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 14 from 21 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 14

Moving on to step 3:
The number 14 fits into 72 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 70 from 72 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 14

Let's proceed to step 4:
20 divided by 14 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we take 14 away from 20, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 14

On to step 5:
14 goes into 68 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 1514.0
If we take 56 away from 68, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 14

Moving on to step 6:
The number 14 fits into 122 8 times, leaving a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 15148.0
Subtracting 112 from 122 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 14

Going ahead to step 7:
14 can be fit into 105 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 151487.0
If we subtract 98 from 105, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 14

On to step 8:
14 can be fit into 74 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 1514875.0
If we subtract 70 from 74, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 14, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 1514875.2
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1514875.28
If we take 112 away from 120, 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.

Advancing to step 11:
80 divided by 14 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1514875.285
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
14 goes into 100 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 1514875.2857
Deduct 98 from 100 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
14 goes into 20 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1514875.28571
If we take 14 away from 20, we end up with 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 14:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1514875.285714
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
40 divided by 14 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 1514875.2857142
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
14 goes into 120 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1514875.28571428
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 1514875.28571428 with a remainder of 8e-09.
