286871 ÷ 14 
The aim is to understand the frequency of 14 in 286871.

Step 1:
2 divided by 14 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 14

Advancing to step 2:
If we divide 28 by 14, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 28 from 28.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 14

Step 3:
If we divide 6 by 14, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 14

Going ahead to step 4:
When dividing 68 by 14, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 204.0
The remainder is 12 after subtracting 56 from 68.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 14

Advancing to step 5:
14 can be fit into 127 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2049.0
Subtracting 126 from 127 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 14

Moving on to step 6:
11 divided by 14 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 20490.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 14 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 20490.7
Subtract 98 from 110 to 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.

Going ahead to step 8:
120 divided by 14 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 20490.78
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.

On to step 9:
The number 14 fits into 80 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 20490.785
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.

Step 10:
If we divide 100 by 14, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 20490.7857
If we take 98 away from 100, we end up 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.

Moving on to step 11:
20 divided by 14 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 20490.78571
Subtracting 14 from 20 leaves us 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.

Step 12:
60 divided by 14 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 20490.785714
Subtract 56 from 60 to 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.

Let's proceed to step 13:
14 goes into 40 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 20490.7857142
If we take 28 away from 40, we end up 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.

Let's proceed to step 14:
If we divide 120 by 14, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 20490.78571428
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.

In conclusion, the division gives 20490.78571428 with a balance of 8e-09.
