880669 ÷ 28 
The aim is to understand the frequency of 28 in 880669.

Moving on to step 1:
28 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 28

On to step 2:
28 goes into 88 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 4 after subtracting 84 from 88.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 28

Advancing to step 3:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 28 from 40 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 28

Step 4:
When dividing 126 by 28, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
Subtract 112 from 126 to get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 28

Step 5:
When dividing 146 by 28, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 3145.0
Subtract 140 from 146 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 28

Advancing to step 6:
The number 28 fits into 69 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 31452.0
Subtract 56 from 69 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
28 goes into 130 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 31452.4
The remainder is 18 after subtracting 112 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
The number 28 fits into 180 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 31452.46
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 31452.464
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 31452.4642
If we take 56 away from 80, 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.

Going ahead to step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 31452.46428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 31452.464285
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 31452.4642857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 31452.46428571
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 31452.46428571 with a remaining 1.2e-08.
