23806391 ÷ 827 
The aim is to understand the frequency of 827 in 23806391.

Step 1:
827 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 827

On to step 2:
827 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 827

Going ahead to step 3:
If we divide 238 by 827, we get 0 and a remainder of 238.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 238 after subtracting 0 from 238.
Include the next digit (0) from the dividend after 238, then repeat: 2380 / 827

Let's proceed to step 4:
2380 divided by 827 is 2 with a remainder of 726.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1654 from 2380 to get 726.
Fetch the next digit (6) from the dividend, attach it to 726 and continue: 7266 / 827

Step 5:
If we divide 7266 by 827, we get 8 and a remainder of 650.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 6616 away from 7266, we end up with 650.
Append the next digit (3) from the dividend to 650 and continue with: 6503 / 827

Moving on to step 6:
827 can be fit into 6503 7 times, resulting in a remainder of 714.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Deduct 5789 from 6503 and we're left with 714.
Bring next digit (9) of the dividend behind the 714 and repeat the process: 7149 / 827

Step 7:
7149 divided by 827 is 8 with a remainder of 533.
The next digit of our result is 8. 
Result so far: 2878.0
If we take 6616 away from 7149, we end up with 533.
Bring next digit (1) of the dividend behind the 533 and repeat the process: 5331 / 827

Advancing to step 8:
The number 827 fits into 5331 6 times, leaving a remainder of 369.
Record the quotient 6 as the next digit in the result. 
Result so far: 28786.0
Subtracting 4962 from 5331 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 9:
When dividing 3690 by 827, we get 4 with a remainder of 382.
Record the quotient 4 as the next digit in the result. 
Result so far: 28786.4
Deduct 3308 from 3690 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 10:
827 goes into 3820 4 times with a remainder of 512.
Write down 4 as next digit of the result. 
Result so far: 28786.44
If we subtract 3308 from 3820, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final result is 28786.44 with a remainder of 0.512.
