We're dividing 23965886 by 285 
The aim is to understand the frequency of 285 in 23965886.

On to step 1:
When dividing 2 by 285, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 285

Moving on to step 2:
The number 285 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 285

Let's proceed to step 3:
285 goes into 239 0 times with a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 239 and we're left with 239.
Take the next digit (6) from the dividend and append it to 239, then repeat: 2396 / 285

Going ahead to step 4:
The number 285 fits into 2396 8 times, leaving a remainder of 116.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 116 after subtracting 2280 from 2396.
Fetch the next digit (5) from the dividend, attach it to 116 and continue: 1165 / 285

Moving on to step 5:
If we divide 1165 by 285, we get 4 and a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 1140 from 1165, we get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 285

Step 6:
285 can be fit into 258 0 times, resulting in a remainder of 258.
The number 0 becomes the next digit in our result. 
Result so far: 840.0
If we take 0 away from 258, we end up with 258.
Include the next digit (8) from the dividend after 258, then repeat: 2588 / 285

Advancing to step 7:
2588 divided by 285 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 8409.0
Subtracting 2565 from 2588 leaves us with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 285

Step 8:
When dividing 236 by 285, we get 0 with a remainder of 236.
Use 0 as the next digit of our solution. 
Result so far: 84090.0
The remainder is 236 after subtracting 0 from 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
285 can be fit into 2360 8 times, resulting in a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 84090.8
Subtracting 2280 from 2360 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
285 can be fit into 800 2 times, resulting in a remainder of 230.
The next digit of our result is 2. 
Result so far: 84090.82
Subtracting 570 from 800 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
If we divide 2300 by 285, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 84090.828
Deduct 2280 from 2300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
The number 285 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 84090.828
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
When dividing 2000 by 285, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 84090.82807
If we take 1995 away from 2000, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
285 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 84090.82807
If we take 0 away from 50, we end up with 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 15:
The number 285 fits into 500 1 times, leaving a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 84090.8280701
Subtracting 285 from 500 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 16:
285 goes into 2150 7 times with a remainder of 155.
Use 7 as the next digit of our solution. 
Result so far: 84090.82807017
If we take 1995 away from 2150, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

In conclusion, the division gives 84090.82807017 with a balance of 1.55e-07.
