We look at the division of 70380667 by 228 
The aim is to understand the frequency of 228 in 70380667.

Going ahead to step 1:
7 divided by 228 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 228

On to step 2:
If we divide 70 by 228, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 228

Advancing to step 3:
When dividing 703 by 228, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 684 from 703, we get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 228

Step 4:
If we divide 198 by 228, we get 0 and a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 198 leaves us with 198.
Bring next digit (0) of the dividend behind the 198 and repeat the process: 1980 / 228

Step 5:
228 can be fit into 1980 8 times, resulting in a remainder of 156.
The next digit of our result is 8. 
Result so far: 308.0
If we subtract 1824 from 1980, we get 156.
Take the next digit (6) from the dividend and append it to 156, then repeat: 1566 / 228

Going ahead to step 6:
If we divide 1566 by 228, we get 6 and a remainder of 198.
Write down 6 as next digit of the result. 
Result so far: 3086.0
If we subtract 1368 from 1566, we get 198.
Fetch the next digit (6) from the dividend, attach it to 198 and continue: 1986 / 228

Moving on to step 7:
When dividing 1986 by 228, we get 8 with a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 30868.0
Subtract 1824 from 1986 to get 162.
Include the next digit (7) from the dividend after 162, then repeat: 1627 / 228

Let's proceed to step 8:
If we divide 1627 by 228, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 308687.0
If we take 1596 away from 1627, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
The number 228 fits into 310 1 times, leaving a remainder of 82.
The next digit of our result is 1. 
Result so far: 308687.1
Subtracting 228 from 310 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
228 can be fit into 820 3 times, resulting in a remainder of 136.
The next digit of our result is 3. 
Result so far: 308687.13
Subtract 684 from 820 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
When dividing 1360 by 228, we get 5 with a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 308687.135
Subtracting 1140 from 1360 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
228 goes into 2200 9 times with a remainder of 148.
Write down 9 as next digit of the result. 
Result so far: 308687.1359
Subtract 2052 from 2200 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 13:
1480 divided by 228 is 6 with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 308687.13596
Subtract 1368 from 1480 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 14:
228 can be fit into 1120 4 times, resulting in a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 308687.135964
Subtracting 912 from 1120 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 15:
2080 divided by 228 is 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 308687.1359649
Deduct 2052 from 2080 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 16:
280 divided by 228 is 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 308687.13596491
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 308687.13596491 with a remainder of 5.2e-08.
