578694 ÷ 14 
The aim is to understand the frequency of 14 in 578694.

Going ahead to step 1:
When dividing 5 by 14, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 14

Moving on to step 2:
The number 14 fits into 57 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 56 away from 57, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 14

Step 3:
14 can be fit into 18 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 14 from 18 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 14

On to step 4:
If we divide 46 by 14, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 413.0
If we subtract 42 from 46, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 14

Advancing to step 5:
When dividing 49 by 14, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 4133.0
The remainder is 7 after subtracting 42 from 49.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 14

Step 6:
14 goes into 74 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 41335.0
Subtracting 70 from 74 leaves us 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.

Moving on to step 7:
14 goes into 40 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 41335.2
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.

Going ahead to step 8:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 41335.28
If we subtract 112 from 120, we get 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 9:
14 can be fit into 80 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 41335.285
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 10:
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: 41335.2857
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.

Moving on to step 11:
The number 14 fits into 20 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 41335.28571
Subtract 14 from 20 to 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.

Moving on to step 12:
When dividing 60 by 14, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 41335.285714
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.

Let's proceed to step 13:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 41335.2857142
If we take 28 away from 40, we end up 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.

Going ahead to step 14:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 41335.28571428
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 41335.28571428 with a remainder of 8e-09.
