12118098 divided by 287 
The aim is to understand the frequency of 287 in 12118098.

On to step 1:
287 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 287

Let's proceed to step 2:
12 divided by 287 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 287

Moving on to step 3:
If we divide 121 by 287, we get 0 and a remainder of 121.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Append the next digit (1) from the dividend to 121 and continue with: 1211 / 287

Step 4:
If we divide 1211 by 287, we get 4 and a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1148 from 1211 and we're left with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 287

On to step 5:
287 goes into 638 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 574 from 638 to get 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 287

Advancing to step 6:
The number 287 fits into 640 2 times, leaving a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 422.0
Subtract 574 from 640 to get 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 287

Let's proceed to step 7:
287 can be fit into 669 2 times, resulting in a remainder of 95.
The number 2 becomes the next digit in our result. 
Result so far: 4222.0
If we subtract 574 from 669, we get 95.
Grab the next digit (8) from the dividend, add it to 95, then carry on: 958 / 287

Advancing to step 8:
287 can be fit into 958 3 times, resulting in a remainder of 97.
The next digit of our result is 3. 
Result so far: 42223.0
If we take 861 away from 958, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
If we divide 970 by 287, we get 3 and a remainder of 109.
The number 3 becomes the next digit in our result. 
Result so far: 42223.3
If we take 861 away from 970, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 10:
When dividing 1090 by 287, we get 3 with a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 42223.33
Deduct 861 from 1090 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final outcome is 42223.33, with a leftover of 0.229.
