We look at the division of 678580 by 14 
The aim is to understand the frequency of 14 in 678580.

Going ahead to step 1:
When dividing 6 by 14, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 14

On to step 2:
The number 14 fits into 67 4 times, leaving a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 56 from 67 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 14

Advancing to step 3:
If we divide 118 by 14, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 112 from 118 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 14

Let's proceed to step 4:
When dividing 65 by 14, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Deduct 56 from 65 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 14

Step 5:
If we divide 98 by 14, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 4847.0
Subtracting 98 from 98 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 14

Moving on to step 6:
14 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48470.0
If we take 0 away from 0, we end up 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.

Advancing to step 7:
14 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48470.0
If we take 0 away from 0, we end up 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.

On to step 8:
14 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48470.0
Subtract 0 from 0 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.

The final outcome is 48470.0, with a leftover of 0.0.
