312391 ÷ 14 
The aim is to understand the frequency of 14 in 312391.

Let's proceed to step 1:
The number 14 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 14

On to step 2:
When dividing 31 by 14, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 3 after subtracting 28 from 31.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 14

Advancing to step 3:
32 divided by 14 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 4 after subtracting 28 from 32.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 14

On to step 4:
The number 14 fits into 43 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 223.0
If we subtract 42 from 43, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 14

On to step 5:
When dividing 19 by 14, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 2231.0
If we subtract 14 from 19, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 14

Let's proceed to step 6:
51 divided by 14 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 22313.0
The remainder is 9 after subtracting 42 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 14, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 22313.6
Subtract 84 from 90 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.

Moving on to step 8:
If we divide 60 by 14, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 22313.64
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.

On to step 9:
If we divide 40 by 14, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 22313.642
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.

On to step 10:
14 goes into 120 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 22313.6428
Deduct 112 from 120 and we're left 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 11:
14 goes into 80 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 22313.64285
Subtracting 70 from 80 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 14, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 22313.642857
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 13:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 22313.6428571
The remainder is 6 after subtracting 14 from 20.
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 14:
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: 22313.64285714
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.

After the division, we end up with 22313.64285714 and a remainder of 4e-09.
