Let's divide 250860 by 14
The aim is to understand the frequency of 14 in 250860.

Step 1:
14 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 14

Going ahead to step 2:
25 divided by 14 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 14 from 25, we get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 14

Going ahead to step 3:
When dividing 110 by 14, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 98 from 110 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 14

Going ahead to step 4:
14 goes into 128 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
The remainder is 2 after subtracting 126 from 128.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 14

Step 5:
The number 14 fits into 26 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1791.0
Subtracting 14 from 26 leaves us with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 14

On to step 6:
14 can be fit into 120 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 17918.0
Deduct 112 from 120 and we're left 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.

Moving on to step 7:
The number 14 fits into 80 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 17918.5
Subtracting 70 from 80 leaves us 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.

Advancing to step 8:
14 can be fit into 100 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 17918.57
Subtracting 98 from 100 leaves us 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.

Step 9:
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: 17918.571
Subtract 14 from 20 to get 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 10:
When dividing 60 by 14, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 17918.5714
If we take 56 away from 60, we end up 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.

Moving on to step 11:
14 goes into 40 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 17918.57142
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 12:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 17918.571428
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.

Step 13:
If we divide 80 by 14, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 17918.5714285
If we subtract 70 from 80, we get 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 14:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 17918.57142857
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 17918.57142857, with a leftover of 2e-09.
