We look at the division of 13866690 by 795 
The aim is to understand the frequency of 795 in 13866690.

On to step 1:
When dividing 1 by 795, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 795

Advancing to step 2:
795 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 795

On to step 3:
When dividing 138 by 795, we get 0 with a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 138 and we're left with 138.
Take the next digit (6) from the dividend and append it to 138, then repeat: 1386 / 795

Step 4:
795 goes into 1386 1 times with a remainder of 591.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 795 from 1386 and we're left with 591.
Grab the next digit (6) from the dividend, add it to 591, then carry on: 5916 / 795

Moving on to step 5:
If we divide 5916 by 795, we get 7 and a remainder of 351.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 5565 from 5916 leaves us with 351.
Fetch the next digit (6) from the dividend, attach it to 351 and continue: 3516 / 795

Step 6:
If we divide 3516 by 795, we get 4 and a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we subtract 3180 from 3516, we get 336.
Include the next digit (9) from the dividend after 336, then repeat: 3369 / 795

Step 7:
When dividing 3369 by 795, we get 4 with a remainder of 189.
Write down 4 as next digit of the result. 
Result so far: 1744.0
Subtracting 3180 from 3369 leaves us with 189.
Include the next digit (0) from the dividend after 189, then repeat: 1890 / 795

On to step 8:
The number 795 fits into 1890 2 times, leaving a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 17442.0
If we take 1590 away from 1890, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 9:
If we divide 3000 by 795, we get 3 and a remainder of 615.
Put 3 as the next digit of the answer. 
Result so far: 17442.3
Subtract 2385 from 3000 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 10:
If we divide 6150 by 795, we get 7 and a remainder of 585.
The next digit of our result is 7. 
Result so far: 17442.37
If we take 5565 away from 6150, we end up with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 11:
The number 795 fits into 5850 7 times, leaving a remainder of 285.
Put 7 as the next digit of the answer. 
Result so far: 17442.377
The remainder is 285 after subtracting 5565 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The final result is 17442.377 with a remainder of 0.0285.
