Let's divide 143219 by 14
The aim is to understand the frequency of 14 in 143219.

Advancing to step 1:
14 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 14

Let's proceed to step 2:
When dividing 14 by 14, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 14 away from 14, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 14

Step 3:
14 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 14

Moving on to step 4:
When dividing 32 by 14, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 102.0
If we subtract 28 from 32, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 14

Step 5:
The number 14 fits into 41 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 1022.0
Deduct 28 from 41 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 14

Advancing to step 6:
14 goes into 139 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 10229.0
Deduct 126 from 139 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 14, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 10229.9
Deduct 126 from 130 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 8:
14 goes into 40 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 10229.92
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.

Moving on to step 9:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10229.928
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.

On to step 10:
14 goes into 80 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10229.9285
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
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: 10229.92857
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 12:
14 goes into 20 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 10229.928571
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.

Let's proceed to step 13:
If we divide 60 by 14, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 10229.9285714
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 14:
14 goes into 40 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 10229.92857142
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.

In conclusion, the division gives 10229.92857142 with a balance of 1.2e-08.
