We look at the division of 28089217 by 451 
The aim is to understand the frequency of 451 in 28089217.

Advancing to step 1:
451 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 451

Moving on to step 2:
The number 451 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 451

Going ahead to step 3:
The number 451 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 280, we get 280.
Bring next digit (8) of the dividend behind the 280 and repeat the process: 2808 / 451

Moving on to step 4:
When dividing 2808 by 451, we get 6 with a remainder of 102.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 2706 away from 2808, we end up with 102.
Include the next digit (9) from the dividend after 102, then repeat: 1029 / 451

Moving on to step 5:
The number 451 fits into 1029 2 times, leaving a remainder of 127.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtract 902 from 1029 to get 127.
Take the next digit (2) from the dividend and append it to 127, then repeat: 1272 / 451

Step 6:
451 can be fit into 1272 2 times, resulting in a remainder of 370.
Use 2 as the next digit of our solution. 
Result so far: 622.0
If we take 902 away from 1272, we end up with 370.
Append the next digit (1) from the dividend to 370 and continue with: 3701 / 451

Advancing to step 7:
If we divide 3701 by 451, we get 8 and a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 6228.0
Subtracting 3608 from 3701 leaves us with 93.
Grab the next digit (7) from the dividend, add it to 93, then carry on: 937 / 451

Step 8:
451 can be fit into 937 2 times, resulting in a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 62282.0
Subtracting 902 from 937 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
350 divided by 451 is 0 with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 62282.0
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
3500 divided by 451 is 7 with a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 62282.07
Subtract 3157 from 3500 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 11:
The number 451 fits into 3430 7 times, leaving a remainder of 273.
Record the quotient 7 as the next digit in the result. 
Result so far: 62282.077
Subtract 3157 from 3430 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

The quotient of the division is 62282.077, and the remainder is 0.0273.
