We're dividing 28548440 by 85 
The aim is to understand the frequency of 85 in 28548440.

Moving on to step 1:
2 divided by 85 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 85

Moving on to step 2:
85 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 85

Step 3:
85 goes into 285 3 times with a remainder of 30.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 30 after subtracting 255 from 285.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 85

Step 4:
When dividing 304 by 85, we get 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 255 away from 304, we end up with 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 85

Moving on to step 5:
85 goes into 498 5 times with a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
The remainder is 73 after subtracting 425 from 498.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 85

Let's proceed to step 6:
The number 85 fits into 734 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 3358.0
Deduct 680 from 734 and we're left with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 85

On to step 7:
85 goes into 544 6 times with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 33586.0
Subtracting 510 from 544 leaves us with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 85

On to step 8:
340 divided by 85 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 335864.0
Subtract 340 from 340 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 85, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 335864.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
0 divided by 85 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 335864.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 335864.0, with a leftover of 0.0.
