140407 divided by 14 
The aim is to understand the frequency of 14 in 140407.

Let's proceed to step 1:
14 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 14

Moving on to step 2:
14 can be fit into 14 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 14 away from 14, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 14

Advancing to step 3:
If we divide 0 by 14, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 14

Advancing to step 4:
14 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 14

Step 5:
When dividing 40 by 14, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1002.0
Subtract 28 from 40 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 14

On to step 6:
14 can be fit into 127 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 10029.0
The remainder is 1 after subtracting 126 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 14 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10029.0
Subtract 0 from 10 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.

On to step 8:
When dividing 100 by 14, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 10029.07
Deduct 98 from 100 and we're left 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 9:
The number 14 fits into 20 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 10029.071
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.

Step 10:
60 divided by 14 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 10029.0714
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.

Advancing to step 11:
14 goes into 40 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 10029.07142
If we subtract 28 from 40, we 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.

Moving on to step 12:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10029.071428
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 13:
If we divide 80 by 14, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10029.0714285
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.

On to step 14:
100 divided by 14 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 10029.07142857
Deduct 98 from 100 and we're left 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.

After the division, we end up with 10029.07142857 and a remainder of 2e-09.
