We're dividing 398551 by 14 
The aim is to understand the frequency of 14 in 398551.

Moving on to step 1:
The number 14 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 14

Let's proceed to step 2:
14 goes into 39 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 28 from 39 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 14

Let's proceed to step 3:
118 divided by 14 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 112 away from 118, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 14

Let's proceed to step 4:
The number 14 fits into 65 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 284.0
Deduct 56 from 65 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 14

Going ahead to step 5:
14 goes into 95 6 times with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 2846.0
If we take 84 away from 95, we end up with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 14

Going ahead to step 6:
The number 14 fits into 111 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 28467.0
Deduct 98 from 111 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 14, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 28467.9
If we subtract 126 from 130, 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.

Going ahead to step 8:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 28467.92
The remainder is 12 after subtracting 28 from 40.
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 9:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 28467.928
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.

Let's proceed to step 10:
80 divided by 14 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 28467.9285
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.

Step 11:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 28467.92857
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.

Let's proceed to step 12:
The number 14 fits into 20 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 28467.928571
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 13:
60 divided by 14 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 28467.9285714
Subtracting 56 from 60 leaves us 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.

Advancing to step 14:
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: 28467.92857142
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 28467.92857142 and a remainder of 1.2e-08.
