99887497 ÷ 228 
The aim is to understand the frequency of 228 in 99887497.

Let's proceed to step 1:
9 divided by 228 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 228

Moving on to step 2:
228 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Grab the next digit (8) from the dividend, add it to 99, then carry on: 998 / 228

On to step 3:
228 goes into 998 4 times with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 912 away from 998, we end up with 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 228

Let's proceed to step 4:
When dividing 868 by 228, we get 3 with a remainder of 184.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 684 from 868, we get 184.
Include the next digit (7) from the dividend after 184, then repeat: 1847 / 228

Let's proceed to step 5:
1847 divided by 228 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 438.0
The remainder is 23 after subtracting 1824 from 1847.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 228

Step 6:
If we divide 234 by 228, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 4381.0
The remainder is 6 after subtracting 228 from 234.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 228

Moving on to step 7:
When dividing 69 by 228, we get 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 43810.0
If we subtract 0 from 69, we get 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 228

Let's proceed to step 8:
If we divide 697 by 228, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 438103.0
Subtracting 684 from 697 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
228 goes into 130 0 times with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 438103.0
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
The number 228 fits into 1300 5 times, leaving a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 438103.05
Deduct 1140 from 1300 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
1600 divided by 228 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 438103.057
Subtract 1596 from 1600 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
40 divided by 228 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 438103.057
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
The number 228 fits into 400 1 times, leaving a remainder of 172.
Put 1 as the next digit of the answer. 
Result so far: 438103.05701
If we subtract 228 from 400, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 14:
1720 divided by 228 is 7 with a remainder of 124.
Write down 7 as next digit of the result. 
Result so far: 438103.057017
Deduct 1596 from 1720 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 15:
The number 228 fits into 1240 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 438103.0570175
Subtract 1140 from 1240 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 16:
If we divide 1000 by 228, we get 4 and a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 438103.05701754
If we subtract 912 from 1000, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 438103.05701754, with a leftover of 8.8e-08.
