We look at the division of 28455125 by 801 
The aim is to understand the frequency of 801 in 28455125.

Let's proceed to step 1:
801 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 801

Step 2:
801 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 801

Advancing to step 3:
If we divide 284 by 801, we get 0 and a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 284 to get 284.
Include the next digit (5) from the dividend after 284, then repeat: 2845 / 801

Step 4:
801 goes into 2845 3 times with a remainder of 442.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 442 after subtracting 2403 from 2845.
Fetch the next digit (5) from the dividend, attach it to 442 and continue: 4425 / 801

Step 5:
801 can be fit into 4425 5 times, resulting in a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 4005 from 4425 and we're left with 420.
Include the next digit (1) from the dividend after 420, then repeat: 4201 / 801

Let's proceed to step 6:
801 can be fit into 4201 5 times, resulting in a remainder of 196.
The next digit of our result is 5. 
Result so far: 355.0
Deduct 4005 from 4201 and we're left with 196.
Include the next digit (2) from the dividend after 196, then repeat: 1962 / 801

Let's proceed to step 7:
801 can be fit into 1962 2 times, resulting in a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 3552.0
Deduct 1602 from 1962 and we're left with 360.
Append the next digit (5) from the dividend to 360 and continue with: 3605 / 801

Going ahead to step 8:
801 goes into 3605 4 times with a remainder of 401.
Record the quotient 4 as the next digit in the result. 
Result so far: 35524.0
The remainder is 401 after subtracting 3204 from 3605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 9:
801 can be fit into 4010 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 35524.5
The remainder is 5 after subtracting 4005 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 801 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 35524.5
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 801, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 35524.5
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 35524.5, and the remainder is 0.05.
