124840 divided by 14 
The aim is to understand the frequency of 14 in 124840.

Advancing to step 1:
When dividing 1 by 14, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 14

Advancing to step 2:
12 divided by 14 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 14

Let's proceed to step 3:
124 divided by 14 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 112 from 124, we get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 14

Step 4:
14 goes into 128 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 126 away from 128, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 14

On to step 5:
If we divide 24 by 14, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 891.0
If we subtract 14 from 24, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 14

Let's proceed to step 6:
14 can be fit into 100 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 8917.0
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 7:
20 divided by 14 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 8917.1
If we take 14 away from 20, 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.

Moving on to step 8:
14 goes into 60 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 8917.14
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.

Let's proceed to step 9:
The number 14 fits into 40 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 8917.142
Subtracting 28 from 40 leaves us 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.

Moving on to step 10:
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: 8917.1428
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.

Moving on 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: 8917.14285
Deduct 70 from 80 and we're left 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.

Moving on to step 12:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 8917.142857
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 13:
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: 8917.1428571
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 14:
14 goes into 60 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 8917.14285714
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.

After the division, we end up with 8917.14285714 and a remainder of 4e-09.
