Let's divide 698235 by 28
The aim is to understand the frequency of 28 in 698235.

On to step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 28

Advancing to step 2:
The number 28 fits into 69 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 56 from 69 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 28

Advancing to step 3:
When dividing 138 by 28, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 26 after subtracting 112 from 138.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 28

On to step 4:
The number 28 fits into 262 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 249.0
Subtract 252 from 262 to get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 28

On to step 5:
28 can be fit into 103 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 2493.0
The remainder is 19 after subtracting 84 from 103.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 28

On to step 6:
The number 28 fits into 195 6 times, leaving a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 24936.0
If we subtract 168 from 195, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
270 divided by 28 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 24936.9
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
28 goes into 180 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 24936.96
If we subtract 168 from 180, 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.

On to step 9:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 24936.964
If we take 112 away from 120, we end up 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:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 24936.9642
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.

Moving on to step 11:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 24936.96428
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.

Let's proceed to step 12:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 24936.964285
Subtracting 140 from 160 leaves us 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.

On to step 13:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 24936.9642857
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.

Step 14:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 24936.96428571
Deduct 28 from 40 and we're left 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 24936.96428571 and a remainder of 1.2e-08.
