Let's divide 354943 by 14
The aim is to understand the frequency of 14 in 354943.

Going ahead to step 1:
The number 14 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 14

Step 2:
If we divide 35 by 14, we get 2 and a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 28 from 35 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 14

Let's proceed to step 3:
If we divide 74 by 14, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 4 after subtracting 70 from 74.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 14

Going ahead to step 4:
The number 14 fits into 49 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 253.0
If we take 42 away from 49, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 14

Moving on to step 5:
When dividing 74 by 14, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 2535.0
If we subtract 70 from 74, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 14

Let's proceed to step 6:
When dividing 43 by 14, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 25353.0
The remainder is 1 after subtracting 42 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 14, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 25353.0
If we subtract 0 from 10, 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.

Moving on to step 8:
14 goes into 100 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 25353.07
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.

Advancing to step 9:
When dividing 20 by 14, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 25353.071
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 10:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 25353.0714
Subtract 56 from 60 to 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.

Step 11:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 25353.07142
The remainder is 12 after subtracting 28 from 40.
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 12:
The number 14 fits into 120 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 25353.071428
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.

Let's proceed to step 13:
14 goes into 80 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 25353.0714285
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 14:
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: 25353.07142857
Deduct 98 from 100 and we're left 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.

In conclusion, the division gives 25353.07142857 with a balance of 2e-09.
