858378 divided by 14 
The aim is to understand the frequency of 14 in 858378.

Advancing to step 1:
14 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 14

Going ahead to step 2:
When dividing 85 by 14, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 84 from 85, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 14

Step 3:
18 divided by 14 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 14 from 18, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 14

Let's proceed to step 4:
43 divided by 14 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 613.0
The remainder is 1 after subtracting 42 from 43.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 14

Advancing to step 5:
14 goes into 17 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 6131.0
If we take 14 away from 17, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 14

Let's proceed to step 6:
14 goes into 38 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 61312.0
The remainder is 10 after subtracting 28 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 61312.7
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.

Advancing 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: 61312.71
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.

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: 61312.714
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.

Going ahead to step 10:
If we divide 40 by 14, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 61312.7142
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.
Record the quotient 8 as the next digit in the result. 
Result so far: 61312.71428
The remainder is 8 after subtracting 112 from 120.
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 12:
When dividing 80 by 14, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 61312.714285
Subtracting 70 from 80 leaves us 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:
When dividing 100 by 14, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 61312.7142857
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.

Moving on to step 14:
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: 61312.71428571
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.

Our division results in 61312.71428571 with a remaining 6e-09.
