8823404 divided by 818 
The aim is to understand the frequency of 818 in 8823404.

Advancing to step 1:
8 divided by 818 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 818

On to step 2:
If we divide 88 by 818, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Append the next digit (2) from the dividend to 88 and continue with: 882 / 818

Let's proceed to step 3:
If we divide 882 by 818, we get 1 and a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 818 from 882, we get 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 818

Advancing to step 4:
When dividing 643 by 818, we get 0 with a remainder of 643.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 643 and we're left with 643.
Grab the next digit (4) from the dividend, add it to 643, then carry on: 6434 / 818

Let's proceed to step 5:
If we divide 6434 by 818, we get 7 and a remainder of 708.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 5726 from 6434, we get 708.
Include the next digit (0) from the dividend after 708, then repeat: 7080 / 818

Moving on to step 6:
When dividing 7080 by 818, we get 8 with a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 1078.0
Subtracting 6544 from 7080 leaves us with 536.
Take the next digit (4) from the dividend and append it to 536, then repeat: 5364 / 818

Step 7:
If we divide 5364 by 818, we get 6 and a remainder of 456.
The number 6 becomes the next digit in our result. 
Result so far: 10786.0
If we take 4908 away from 5364, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 8:
818 can be fit into 4560 5 times, resulting in a remainder of 470.
The next digit of our result is 5. 
Result so far: 10786.5
Subtracting 4090 from 4560 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 9:
When dividing 4700 by 818, we get 5 with a remainder of 610.
Write down 5 as next digit of the result. 
Result so far: 10786.55
If we take 4090 away from 4700, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The quotient of the division is 10786.55, and the remainder is 0.61.
