391283 ÷ 14 
The aim is to understand the frequency of 14 in 391283.

On to step 1:
14 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 14

Going ahead to step 2:
If we divide 39 by 14, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 28 from 39, we get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 14

Going ahead to step 3:
14 can be fit into 111 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 98 from 111 leaves us with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 14

On to step 4:
If we divide 132 by 14, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 279.0
If we subtract 126 from 132, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 14

Let's proceed to step 5:
68 divided by 14 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 2794.0
The remainder is 12 after subtracting 56 from 68.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 14

Moving on to step 6:
If we divide 123 by 14, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 27948.0
Subtract 112 from 123 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
14 goes into 110 7 times with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 27948.7
Deduct 98 from 110 and we're left 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.

Going ahead to step 8:
When dividing 120 by 14, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 27948.78
Subtract 112 from 120 to get 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 9:
14 goes into 80 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 27948.785
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.

Step 10:
14 goes into 100 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 27948.7857
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.

Going ahead to step 11:
The number 14 fits into 20 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 27948.78571
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 12:
14 can be fit into 60 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 27948.785714
Deduct 56 from 60 and we're left 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 13:
The number 14 fits into 40 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 27948.7857142
Deduct 28 from 40 and we're left 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.

On to step 14:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 27948.78571428
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.

The final result is 27948.78571428 with a remainder of 8e-09.
