816684 divided by 88 
The aim is to understand the frequency of 88 in 816684.

Step 1:
88 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 88

Let's proceed to step 2:
81 divided by 88 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 88

Let's proceed to step 3:
88 can be fit into 816 9 times, resulting in a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 792 away from 816, we end up with 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 88

Step 4:
88 can be fit into 246 2 times, resulting in a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtracting 176 from 246 leaves us with 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 88

Moving on to step 5:
708 divided by 88 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 928.0
If we subtract 704 from 708, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 88

Going ahead to step 6:
44 divided by 88 is 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 9280.0
Deduct 0 from 44 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
88 can be fit into 440 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9280.5
Deduct 440 from 440 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
88 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9280.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 88, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9280.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 9280.5 with a remaining 0.0.
