643082 divided by 14 
The aim is to understand the frequency of 14 in 643082.

Going ahead to step 1:
If we divide 6 by 14, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 14

Step 2:
If we divide 64 by 14, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 56 from 64 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 14

Step 3:
14 can be fit into 83 5 times, resulting in a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 70 from 83 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 14

Moving on to step 4:
The number 14 fits into 130 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 459.0
Subtract 126 from 130 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 14

Let's proceed to step 5:
14 can be fit into 48 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 4593.0
Deduct 42 from 48 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 14

Going ahead to step 6:
14 can be fit into 62 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 45934.0
If we take 56 away from 62, we end up 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 7:
14 goes into 60 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 45934.4
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 45934.42
Subtract 28 from 40 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 9:
If we divide 120 by 14, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 45934.428
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.

Advancing to step 10:
14 can be fit into 80 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 45934.4285
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.

Moving on to step 11:
100 divided by 14 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 45934.42857
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.

Step 12:
14 goes into 20 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 45934.428571
Subtract 14 from 20 to get 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 13:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 45934.4285714
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.

Moving on to step 14:
14 can be fit into 40 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 45934.42857142
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 45934.42857142 and a remainder of 1.2e-08.
