We look at the division of 218599 by 14 
The aim is to understand the frequency of 14 in 218599.

Advancing to step 1:
2 divided by 14 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 14

Going ahead to step 2:
When dividing 21 by 14, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 14 from 21 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 14

On to step 3:
14 goes into 78 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 70 from 78 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 14

Step 4:
If we divide 85 by 14, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we subtract 84 from 85, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 14

Going ahead to step 5:
When dividing 19 by 14, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1561.0
Subtract 14 from 19 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 14

Let's proceed to step 6:
If we divide 59 by 14, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 15614.0
Subtract 56 from 59 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 14, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 15614.2
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 15614.21
If we subtract 14 from 20, we 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.

On to step 9:
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: 15614.214
If we take 56 away from 60, we end up 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 10:
40 divided by 14 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 15614.2142
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.

Let's proceed to step 11:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 15614.21428
Subtracting 112 from 120 leaves us 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.

Step 12:
When dividing 80 by 14, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 15614.214285
If we take 70 away from 80, we end up 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.

Advancing to step 13:
If we divide 100 by 14, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 15614.2142857
Subtract 98 from 100 to get 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 14:
20 divided by 14 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 15614.21428571
Deduct 14 from 20 and we're left 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.

The final outcome is 15614.21428571, with a leftover of 6e-09.
