769877 divided by 14 
The aim is to understand the frequency of 14 in 769877.

On to step 1:
If we divide 7 by 14, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 14

On to step 2:
The number 14 fits into 76 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 70 from 76, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 14

Let's proceed to step 3:
69 divided by 14 is 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 56 from 69 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 14

Advancing to step 4:
The number 14 fits into 138 9 times, leaving a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 549.0
If we subtract 126 from 138, we get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 14

Moving on to step 5:
If we divide 127 by 14, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 5499.0
The remainder is 1 after subtracting 126 from 127.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 14

Advancing to step 6:
If we divide 17 by 14, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 54991.0
Deduct 14 from 17 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.

Going ahead to step 7:
The number 14 fits into 30 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 54991.2
Deduct 28 from 30 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.

Advancing to step 8:
20 divided by 14 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 54991.21
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.

Moving on to step 9:
The number 14 fits into 60 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 54991.214
The remainder is 4 after subtracting 56 from 60.
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 10:
40 divided by 14 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 54991.2142
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.

Step 11:
14 can be fit into 120 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 54991.21428
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 12:
If we divide 80 by 14, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 54991.214285
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:
The number 14 fits into 100 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 54991.2142857
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.

Going ahead to step 14:
When dividing 20 by 14, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 54991.21428571
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.

The final result is 54991.21428571 with a remainder of 6e-09.
