815161 divided by 14 
The aim is to understand the frequency of 14 in 815161.

Step 1:
8 divided by 14 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 14

On to step 2:
81 divided by 14 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 70 from 81 and we're left with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 14

Advancing to step 3:
14 goes into 115 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 112 from 115 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 14

Step 4:
14 can be fit into 31 2 times, resulting in a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 582.0
Deduct 28 from 31 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 14

Moving on to step 5:
If we divide 36 by 14, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5822.0
If we take 28 away from 36, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 14

Let's proceed to step 6:
The number 14 fits into 81 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 58225.0
Subtracting 70 from 81 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
14 can be fit into 110 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 58225.7
If we take 98 away from 110, 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.

Advancing to step 8:
14 goes into 120 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 58225.78
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.

Advancing to step 9:
80 divided by 14 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 58225.785
Deduct 70 from 80 and we're left 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.

Going ahead to step 10:
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: 58225.7857
The remainder is 2 after subtracting 98 from 100.
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 11:
The number 14 fits into 20 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 58225.78571
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 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: 58225.785714
If we subtract 56 from 60, we 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.

Let's proceed to step 13:
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: 58225.7857142
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.

Advancing to step 14:
120 divided by 14 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 58225.78571428
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.

In conclusion, the division gives 58225.78571428 with a balance of 8e-09.
