We look at the division of 86510865 by 228 
The aim is to understand the frequency of 228 in 86510865.

Advancing to step 1:
8 divided by 228 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 228

Let's proceed to step 2:
When dividing 86 by 228, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 228

Moving on to step 3:
If we divide 865 by 228, we get 3 and a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 684 from 865 leaves us with 181.
Fetch the next digit (1) from the dividend, attach it to 181 and continue: 1811 / 228

Advancing to step 4:
The number 228 fits into 1811 7 times, leaving a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we subtract 1596 from 1811, we get 215.
Fetch the next digit (0) from the dividend, attach it to 215 and continue: 2150 / 228

On to step 5:
When dividing 2150 by 228, we get 9 with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 379.0
If we take 2052 away from 2150, we end up with 98.
Fetch the next digit (8) from the dividend, attach it to 98 and continue: 988 / 228

Let's proceed to step 6:
If we divide 988 by 228, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 3794.0
Subtracting 912 from 988 leaves us with 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 228

Advancing to step 7:
228 can be fit into 766 3 times, resulting in a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 37943.0
If we subtract 684 from 766, we get 82.
Include the next digit (5) from the dividend after 82, then repeat: 825 / 228

Going ahead to step 8:
If we divide 825 by 228, we get 3 and a remainder of 141.
Use 3 as the next digit of our solution. 
Result so far: 379433.0
The remainder is 141 after subtracting 684 from 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 9:
When dividing 1410 by 228, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 379433.6
Subtracting 1368 from 1410 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
420 divided by 228 is 1 with a remainder of 192.
The number 1 becomes the next digit in our result. 
Result so far: 379433.61
The remainder is 192 after subtracting 228 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 11:
The number 228 fits into 1920 8 times, leaving a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 379433.618
If we subtract 1824 from 1920, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 12:
960 divided by 228 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 379433.6184
Subtracting 912 from 960 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
228 goes into 480 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 379433.61842
Deduct 456 from 480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
240 divided by 228 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 379433.618421
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
The number 228 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 379433.618421
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
When dividing 1200 by 228, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 379433.61842105
If we take 1140 away from 1200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 379433.61842105 and a remainder of 6e-08.
