We look at the division of 80894833 by 285 
The aim is to understand the frequency of 285 in 80894833.

Going ahead to step 1:
The number 285 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 285

Going ahead to step 2:
The number 285 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 285

Let's proceed to step 3:
The number 285 fits into 808 2 times, leaving a remainder of 238.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 570 from 808 to get 238.
Append the next digit (9) from the dividend to 238 and continue with: 2389 / 285

Let's proceed to step 4:
If we divide 2389 by 285, we get 8 and a remainder of 109.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 109 after subtracting 2280 from 2389.
Include the next digit (4) from the dividend after 109, then repeat: 1094 / 285

Let's proceed to step 5:
285 goes into 1094 3 times with a remainder of 239.
Write down 3 as next digit of the result. 
Result so far: 283.0
If we subtract 855 from 1094, we get 239.
Include the next digit (8) from the dividend after 239, then repeat: 2398 / 285

Going ahead to step 6:
When dividing 2398 by 285, we get 8 with a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 2838.0
Deduct 2280 from 2398 and we're left with 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 285

Let's proceed to step 7:
285 goes into 1183 4 times with a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 28384.0
Subtract 1140 from 1183 to get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 285

Advancing to step 8:
When dividing 433 by 285, we get 1 with a remainder of 148.
Record the quotient 1 as the next digit in the result. 
Result so far: 283841.0
Subtract 285 from 433 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
285 can be fit into 1480 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 283841.5
Subtract 1425 from 1480 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
When dividing 550 by 285, we get 1 with a remainder of 265.
Put 1 as the next digit of the answer. 
Result so far: 283841.51
Deduct 285 from 550 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 11:
285 goes into 2650 9 times with a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 283841.519
If we subtract 2565 from 2650, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
850 divided by 285 is 2 with a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 283841.5192
Deduct 570 from 850 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
When dividing 2800 by 285, we get 9 with a remainder of 235.
The number 9 becomes the next digit in our result. 
Result so far: 283841.51929
Subtracting 2565 from 2800 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 14:
The number 285 fits into 2350 8 times, leaving a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 283841.519298
Subtract 2280 from 2350 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 15:
285 can be fit into 700 2 times, resulting in a remainder of 130.
The next digit of our result is 2. 
Result so far: 283841.5192982
Deduct 570 from 700 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 16:
When dividing 1300 by 285, we get 4 with a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 283841.51929824
If we subtract 1140 from 1300, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 283841.51929824 with a remainder of 1.6e-07.
