80928879 divided by 285 
The aim is to understand the frequency of 285 in 80928879.

Going ahead to step 1:
285 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 285

On to step 2:
If we divide 80 by 285, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 285

On to step 3:
809 divided by 285 is 2 with a remainder of 239.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 570 from 809, we get 239.
Bring next digit (2) of the dividend behind the 239 and repeat the process: 2392 / 285

Advancing to step 4:
285 goes into 2392 8 times with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 2280 away from 2392, we end up with 112.
Include the next digit (8) from the dividend after 112, then repeat: 1128 / 285

Step 5:
If we divide 1128 by 285, we get 3 and a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 283.0
If we subtract 855 from 1128, we get 273.
Bring next digit (8) of the dividend behind the 273 and repeat the process: 2738 / 285

Let's proceed to step 6:
When dividing 2738 by 285, we get 9 with a remainder of 173.
Use 9 as the next digit of our solution. 
Result so far: 2839.0
Deduct 2565 from 2738 and we're left with 173.
Fetch the next digit (7) from the dividend, attach it to 173 and continue: 1737 / 285

Going ahead to step 7:
285 goes into 1737 6 times with a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 28396.0
The remainder is 27 after subtracting 1710 from 1737.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 285

Let's proceed to step 8:
If we divide 279 by 285, we get 0 and a remainder of 279.
Write down 0 as next digit of the result. 
Result so far: 283960.0
Subtracting 0 from 279 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 9:
2790 divided by 285 is 9 with a remainder of 225.
The number 9 becomes the next digit in our result. 
Result so far: 283960.9
Subtract 2565 from 2790 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
285 goes into 2250 7 times with a remainder of 255.
Use 7 as the next digit of our solution. 
Result so far: 283960.97
Subtracting 1995 from 2250 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 11:
285 goes into 2550 8 times with a remainder of 270.
The number 8 becomes the next digit in our result. 
Result so far: 283960.978
If we take 2280 away from 2550, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
The number 285 fits into 2700 9 times, leaving a remainder of 135.
Use 9 as the next digit of our solution. 
Result so far: 283960.9789
If we take 2565 away from 2700, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 13:
285 goes into 1350 4 times with a remainder of 210.
Write down 4 as next digit of the result. 
Result so far: 283960.97894
If we take 1140 away from 1350, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 14:
The number 285 fits into 2100 7 times, leaving a remainder of 105.
The next digit of our result is 7. 
Result so far: 283960.978947
Subtract 1995 from 2100 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 15:
285 can be fit into 1050 3 times, resulting in a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 283960.9789473
Subtract 855 from 1050 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 16:
The number 285 fits into 1950 6 times, leaving a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 283960.97894736
If we take 1710 away from 1950, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The quotient of the division is 283960.97894736, and the remainder is 2.4e-07.
