280696 divided by 88 
The aim is to understand the frequency of 88 in 280696.

Step 1:
2 divided by 88 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 88

On to step 2:
88 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 88

Let's proceed to step 3:
When dividing 280 by 88, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 264 from 280, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 88

Going ahead to step 4:
If we divide 166 by 88, we get 1 and a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 88 from 166, we get 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 88

Going ahead to step 5:
88 goes into 789 8 times with a remainder of 85.
Use 8 as the next digit of our solution. 
Result so far: 318.0
If we take 704 away from 789, we end up with 85.
Take the next digit (6) from the dividend and append it to 85, then repeat: 856 / 88

Step 6:
The number 88 fits into 856 9 times, leaving a remainder of 64.
The next digit of our result is 9. 
Result so far: 3189.0
Subtract 792 from 856 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 7:
88 can be fit into 640 7 times, resulting in a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 3189.7
If we take 616 away from 640, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
88 can be fit into 240 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 3189.72
If we subtract 176 from 240, we 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.

On to step 9:
88 can be fit into 640 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 3189.727
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
88 can be fit into 240 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 3189.7272
Subtract 176 from 240 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.

Step 11:
When dividing 640 by 88, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 3189.72727
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
88 can be fit into 240 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 3189.727272
Subtract 176 from 240 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.

Advancing to step 13:
88 can be fit into 640 7 times, resulting in a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 3189.7272727
If we take 616 away from 640, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
If we divide 240 by 88, we get 2 and a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 3189.72727272
Deduct 176 from 240 and we're left 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.

The final outcome is 3189.72727272, with a leftover of 6.4e-08.
