We look at the division of 164421 by 14 
The aim is to understand the frequency of 14 in 164421.

Step 1:
If we divide 1 by 14, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 14

Moving on to step 2:
If we divide 16 by 14, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 14 from 16, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 14

Step 3:
14 goes into 24 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 14 from 24, we get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 14

On to step 4:
When dividing 104 by 14, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 98 from 104, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 14

Going ahead to step 5:
The number 14 fits into 62 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1174.0
Subtracting 56 from 62 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 14

On to step 6:
If we divide 61 by 14, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 11744.0
Deduct 56 from 61 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 14 fits into 50 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 11744.3
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
14 goes into 80 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 11744.35
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.

On to step 9:
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: 11744.357
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 10:
If we divide 20 by 14, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 11744.3571
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.

Advancing to step 11:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 11744.35714
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.

Step 12:
14 goes into 40 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 11744.357142
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.

Advancing to step 13:
If we divide 120 by 14, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11744.3571428
Subtracting 112 from 120 leaves us 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.

Advancing to step 14:
14 goes into 80 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11744.35714285
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.

The final result is 11744.35714285 with a remainder of 1e-08.
