21517713 ÷ 14 
We want to divide 21517713 by 14.

Step 1:
14 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 14

Step 2:
14 goes into 21 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 14 from 21 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 14

Going ahead to step 3:
14 can be fit into 75 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 70 from 75 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 14

On to step 4:
When dividing 51 by 14, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
The remainder is 9 after subtracting 42 from 51.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 14

Advancing to step 5:
14 goes into 97 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 1536.0
Deduct 84 from 97 and we're left with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 14

Going ahead to step 6:
14 goes into 137 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 15369.0
Subtracting 126 from 137 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 14

Going ahead to step 7:
14 goes into 111 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 153697.0
Subtract 98 from 111 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 14

Going ahead to step 8:
When dividing 133 by 14, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1536979.0
Subtracting 126 from 133 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 14 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1536979.5
Subtract 70 from 70 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.

Let's proceed to step 10:
If we divide 0 by 14, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1536979.5
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.

Step 11:
0 divided by 14 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1536979.5
If we subtract 0 from 0, we 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 result is 1536979.5 with a remainder of 0.0.
