We're dividing 36690388 by 717 
The aim is to understand the frequency of 717 in 36690388.

Let's proceed to step 1:
When dividing 3 by 717, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 717

On to step 2:
36 divided by 717 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 717

Advancing to step 3:
717 goes into 366 0 times with a remainder of 366.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 366 and we're left with 366.
Include the next digit (9) from the dividend after 366, then repeat: 3669 / 717

Step 4:
3669 divided by 717 is 5 with a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 3585 from 3669, we get 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 717

Step 5:
If we divide 840 by 717, we get 1 and a remainder of 123.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 717 from 840 leaves us with 123.
Bring next digit (3) of the dividend behind the 123 and repeat the process: 1233 / 717

Going ahead to step 6:
The number 717 fits into 1233 1 times, leaving a remainder of 516.
Put 1 as the next digit of the answer. 
Result so far: 511.0
Deduct 717 from 1233 and we're left with 516.
Bring next digit (8) of the dividend behind the 516 and repeat the process: 5168 / 717

Let's proceed to step 7:
If we divide 5168 by 717, we get 7 and a remainder of 149.
The next digit of our result is 7. 
Result so far: 5117.0
Subtract 5019 from 5168 to get 149.
Include the next digit (8) from the dividend after 149, then repeat: 1498 / 717

Step 8:
717 goes into 1498 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 51172.0
Subtract 1434 from 1498 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
717 can be fit into 640 0 times, resulting in a remainder of 640.
The next digit of our result is 0. 
Result so far: 51172.0
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 10:
717 can be fit into 6400 8 times, resulting in a remainder of 664.
Write down 8 as next digit of the result. 
Result so far: 51172.08
If we take 5736 away from 6400, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Advancing to step 11:
717 goes into 6640 9 times with a remainder of 187.
Put 9 as the next digit of the answer. 
Result so far: 51172.089
Deduct 6453 from 6640 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 12:
717 can be fit into 1870 2 times, resulting in a remainder of 436.
Write down 2 as next digit of the result. 
Result so far: 51172.0892
If we subtract 1434 from 1870, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 13:
4360 divided by 717 is 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 51172.08926
If we take 4302 away from 4360, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
The number 717 fits into 580 0 times, leaving a remainder of 580.
The number 0 becomes the next digit in our result. 
Result so far: 51172.08926
Subtract 0 from 580 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 15:
When dividing 5800 by 717, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 51172.0892608
If we take 5736 away from 5800, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
When dividing 640 by 717, we get 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 51172.0892608
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 51172.0892608 with a remaining 6.4e-07.
