768690 ÷ 28 
The aim is to understand the frequency of 28 in 768690.

Moving on to step 1:
The number 28 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 28

Step 2:
When dividing 76 by 28, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 56 from 76, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 28

Advancing to step 3:
28 can be fit into 208 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 196 away from 208, we end up with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 28

Let's proceed to step 4:
126 divided by 28 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 274.0
If we subtract 112 from 126, we get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 28

Moving on to step 5:
28 can be fit into 149 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 2745.0
Deduct 140 from 149 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 28

Advancing to step 6:
The number 28 fits into 90 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 27453.0
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 28 fits into 60 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 27453.2
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 27453.21
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 28, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 27453.214
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.

On to step 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 27453.2142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 27453.21428
If we subtract 224 from 240, we 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.

On 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: 27453.214285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 27453.2142857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 27453.21428571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 27453.21428571 and a remainder of 1.2e-08.
