389763 ÷ 14 
The aim is to understand the frequency of 14 in 389763.

On to step 1:
When dividing 3 by 14, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 14

On to step 2:
14 goes into 38 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 10 after subtracting 28 from 38.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 14

Moving on to step 3:
109 divided by 14 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 98 from 109 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 14

Moving on to step 4:
117 divided by 14 is 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 278.0
Subtract 112 from 117 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 14

Step 5:
14 can be fit into 56 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 2784.0
If we take 56 away from 56, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 14

Advancing to step 6:
When dividing 3 by 14, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 27840.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 14, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 27840.2
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 27840.21
The remainder is 6 after subtracting 14 from 20.
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 9:
14 can be fit into 60 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 27840.214
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.

Advancing to step 10:
When dividing 40 by 14, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 27840.2142
Subtract 28 from 40 to 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 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: 27840.21428
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 12:
14 can be fit into 80 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 27840.214285
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.

Let's proceed to step 13:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 27840.2142857
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 14:
14 goes into 20 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 27840.21428571
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.

In conclusion, the division gives 27840.21428571 with a balance of 6e-09.
