We look at the division of 28445281 by 658 
The aim is to understand the frequency of 658 in 28445281.

On to step 1:
If we divide 2 by 658, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 658

Let's proceed to step 2:
28 divided by 658 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 658

On to step 3:
If we divide 284 by 658, we get 0 and a remainder of 284.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 284, we end up with 284.
Grab the next digit (4) from the dividend, add it to 284, then carry on: 2844 / 658

Step 4:
If we divide 2844 by 658, we get 4 and a remainder of 212.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2632 from 2844 to get 212.
Append the next digit (5) from the dividend to 212 and continue with: 2125 / 658

Advancing to step 5:
2125 divided by 658 is 3 with a remainder of 151.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 151 after subtracting 1974 from 2125.
Append the next digit (2) from the dividend to 151 and continue with: 1512 / 658

Step 6:
The number 658 fits into 1512 2 times, leaving a remainder of 196.
The next digit of our result is 2. 
Result so far: 432.0
Subtracting 1316 from 1512 leaves us with 196.
Bring next digit (8) of the dividend behind the 196 and repeat the process: 1968 / 658

Moving on to step 7:
When dividing 1968 by 658, we get 2 with a remainder of 652.
Use 2 as the next digit of our solution. 
Result so far: 4322.0
Subtract 1316 from 1968 to get 652.
Append the next digit (1) from the dividend to 652 and continue with: 6521 / 658

Moving on to step 8:
6521 divided by 658 is 9 with a remainder of 599.
The number 9 becomes the next digit in our result. 
Result so far: 43229.0
Subtracting 5922 from 6521 leaves us with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 9:
658 can be fit into 5990 9 times, resulting in a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 43229.9
Subtract 5922 from 5990 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 658 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 43229.91
The remainder is 22 after subtracting 658 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
658 goes into 220 0 times with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 43229.91
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
If we divide 2200 by 658, we get 3 and a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 43229.9103
Subtract 1974 from 2200 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 13:
658 can be fit into 2260 3 times, resulting in a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 43229.91033
Subtracting 1974 from 2260 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The quotient of the division is 43229.91033, and the remainder is 0.000286.
