We look at the division of 778804 by 14 
The aim is to understand the frequency of 14 in 778804.

Advancing to step 1:
The number 14 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 14

Advancing to step 2:
77 divided by 14 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 70 from 77 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 14

Let's proceed to step 3:
The number 14 fits into 78 5 times, leaving a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 70 from 78 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 14

Let's proceed to step 4:
If we divide 88 by 14, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 556.0
The remainder is 4 after subtracting 84 from 88.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 14

Moving on to step 5:
14 goes into 40 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 5562.0
If we take 28 away from 40, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 14

Step 6:
If we divide 124 by 14, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 55628.0
Subtract 112 from 124 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 7:
When dividing 120 by 14, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 55628.8
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.

Going ahead to step 8:
14 goes into 80 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 55628.85
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 14 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 55628.857
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.

Let's proceed to step 10:
20 divided by 14 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 55628.8571
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.

On to step 11:
The number 14 fits into 60 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 55628.85714
If we subtract 56 from 60, we 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 12:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 55628.857142
Subtracting 28 from 40 leaves us 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 13:
120 divided by 14 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 55628.8571428
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 14:
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: 55628.85714285
Subtract 70 from 80 to 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.

After the division, we end up with 55628.85714285 and a remainder of 1e-08.
