We look at the division of 679694 by 28 
The aim is to understand the frequency of 28 in 679694.

On to step 1:
28 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 28

Step 2:
28 can be fit into 67 2 times, resulting in a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 56 from 67, we get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 28

Step 3:
119 divided by 28 is 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 112 from 119 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 28

Step 4:
If we divide 76 by 28, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 242.0
If we subtract 56 from 76, we get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 28

Moving on to step 5:
The number 28 fits into 209 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 2427.0
If we subtract 196 from 209, we get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 28

On to step 6:
28 goes into 134 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 24274.0
If we take 112 away from 134, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
When dividing 220 by 28, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 24274.7
The remainder is 24 after subtracting 196 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24274.78
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 24274.785
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.

Going ahead to step 10:
200 divided by 28 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 24274.7857
If we take 196 away from 200, we end up 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.

On to step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 24274.78571
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.

Moving on to step 12:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 24274.785714
If we subtract 112 from 120, we get 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 13:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 24274.7857142
Subtracting 56 from 80 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.

Step 14:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 24274.78571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 24274.78571428 with a balance of 1.6e-08.
