21687019 divided by 14 
The aim is to understand the frequency of 14 in 21687019.

Going ahead to step 1:
The number 14 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 14

Let's proceed to step 2:
14 can be fit into 21 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 7 after subtracting 14 from 21.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 14

Moving on to step 3:
When dividing 76 by 14, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 70 from 76, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 14

Advancing to step 4:
14 can be fit into 68 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 154.0
The remainder is 12 after subtracting 56 from 68.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 14

Advancing to step 5:
14 goes into 127 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1549.0
Subtract 126 from 127 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 14

On to step 6:
14 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15490.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 14

Going ahead to step 7:
If we divide 101 by 14, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 154907.0
If we subtract 98 from 101, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 14

Step 8:
14 can be fit into 39 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 1549072.0
Subtracting 28 from 39 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
If we divide 110 by 14, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1549072.7
The remainder is 12 after subtracting 98 from 110.
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 goes into 120 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1549072.78
Subtract 112 from 120 to 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.

Going ahead to step 11:
The number 14 fits into 80 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1549072.785
If we take 70 away from 80, we end up with 10.
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.
Use 7 as the next digit of our solution. 
Result so far: 1549072.7857
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.

On to step 13:
14 can be fit into 20 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1549072.78571
Deduct 14 from 20 and we're left 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.

On to step 14:
14 can be fit into 60 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1549072.785714
Deduct 56 from 60 and we're left 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.

Let's proceed to step 15:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1549072.7857142
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 16:
14 can be fit into 120 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1549072.78571428
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.

The quotient of the division is 1549072.78571428, and the remainder is 8e-09.
