We divide 23979851 by 287
The aim is to understand the frequency of 287 in 23979851.

On to step 1:
287 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 287

On to step 2:
287 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 287

Going ahead to step 3:
The number 287 fits into 239 0 times, leaving a remainder of 239.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 239, we get 239.
Take the next digit (7) from the dividend and append it to 239, then repeat: 2397 / 287

Going ahead to step 4:
287 can be fit into 2397 8 times, resulting in a remainder of 101.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 2296 away from 2397, we end up with 101.
Bring next digit (9) of the dividend behind the 101 and repeat the process: 1019 / 287

Moving on to step 5:
1019 divided by 287 is 3 with a remainder of 158.
The next digit of our result is 3. 
Result so far: 83.0
If we subtract 861 from 1019, we get 158.
Append the next digit (8) from the dividend to 158 and continue with: 1588 / 287

Step 6:
287 can be fit into 1588 5 times, resulting in a remainder of 153.
Record the quotient 5 as the next digit in the result. 
Result so far: 835.0
Subtract 1435 from 1588 to get 153.
Include the next digit (5) from the dividend after 153, then repeat: 1535 / 287

Advancing to step 7:
287 goes into 1535 5 times with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 8355.0
If we subtract 1435 from 1535, we get 100.
Grab the next digit (1) from the dividend, add it to 100, then carry on: 1001 / 287

On to step 8:
When dividing 1001 by 287, we get 3 with a remainder of 140.
The next digit of our result is 3. 
Result so far: 83553.0
Deduct 861 from 1001 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 9:
If we divide 1400 by 287, we get 4 and a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 83553.4
The remainder is 252 after subtracting 1148 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 10:
2520 divided by 287 is 8 with a remainder of 224.
The next digit of our result is 8. 
Result so far: 83553.48
The remainder is 224 after subtracting 2296 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 11:
If we divide 2240 by 287, we get 7 and a remainder of 231.
The number 7 becomes the next digit in our result. 
Result so far: 83553.487
The remainder is 231 after subtracting 2009 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 12:
When dividing 2310 by 287, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 83553.4878
The remainder is 14 after subtracting 2296 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
If we divide 140 by 287, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 83553.4878
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
If we divide 1400 by 287, we get 4 and a remainder of 252.
The next digit of our result is 4. 
Result so far: 83553.487804
If we take 1148 away from 1400, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 15:
If we divide 2520 by 287, we get 8 and a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 83553.4878048
If we take 2296 away from 2520, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 16:
287 goes into 2240 7 times with a remainder of 231.
Put 7 as the next digit of the answer. 
Result so far: 83553.48780487
Subtracting 2009 from 2240 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

After the division, we end up with 83553.48780487 and a remainder of 2.31e-07.
