We look at the division of 14666939 by 717 
The aim is to understand the frequency of 717 in 14666939.

On to step 1:
If we divide 1 by 717, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 717

Moving on to step 2:
If we divide 14 by 717, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 717

Advancing to step 3:
146 divided by 717 is 0 with a remainder of 146.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 146, we get 146.
Fetch the next digit (6) from the dividend, attach it to 146 and continue: 1466 / 717

Let's proceed to step 4:
717 goes into 1466 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1434 from 1466 to get 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 717

Step 5:
When dividing 326 by 717, we get 0 with a remainder of 326.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 326 after subtracting 0 from 326.
Fetch the next digit (9) from the dividend, attach it to 326 and continue: 3269 / 717

Moving on to step 6:
3269 divided by 717 is 4 with a remainder of 401.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
If we subtract 2868 from 3269, we get 401.
Append the next digit (3) from the dividend to 401 and continue with: 4013 / 717

Advancing to step 7:
When dividing 4013 by 717, we get 5 with a remainder of 428.
The next digit of our result is 5. 
Result so far: 2045.0
If we subtract 3585 from 4013, we get 428.
Bring next digit (9) of the dividend behind the 428 and repeat the process: 4289 / 717

Step 8:
If we divide 4289 by 717, we get 5 and a remainder of 704.
Record the quotient 5 as the next digit in the result. 
Result so far: 20455.0
The remainder is 704 after subtracting 3585 from 4289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 9:
If we divide 7040 by 717, we get 9 and a remainder of 587.
The number 9 becomes the next digit in our result. 
Result so far: 20455.9
Deduct 6453 from 7040 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Let's proceed to step 10:
717 can be fit into 5870 8 times, resulting in a remainder of 134.
The number 8 becomes the next digit in our result. 
Result so far: 20455.98
If we subtract 5736 from 5870, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 11:
When dividing 1340 by 717, we get 1 with a remainder of 623.
Use 1 as the next digit of our solution. 
Result so far: 20455.981
Subtracting 717 from 1340 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Going ahead to step 12:
The number 717 fits into 6230 8 times, leaving a remainder of 494.
Record the quotient 8 as the next digit in the result. 
Result so far: 20455.9818
Deduct 5736 from 6230 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 13:
4940 divided by 717 is 6 with a remainder of 638.
Record the quotient 6 as the next digit in the result. 
Result so far: 20455.98186
The remainder is 638 after subtracting 4302 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 14:
717 goes into 6380 8 times with a remainder of 644.
Write down 8 as next digit of the result. 
Result so far: 20455.981868
Subtracting 5736 from 6380 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 15:
717 goes into 6440 8 times with a remainder of 704.
Put 8 as the next digit of the answer. 
Result so far: 20455.9818688
Subtract 5736 from 6440 to get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The quotient of the division is 20455.9818688, and the remainder is 7.04e-06.
