We look at the division of 57421268 by 228 
The aim is to understand the frequency of 228 in 57421268.

Advancing to step 1:
If we divide 5 by 228, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 228

On to step 2:
228 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 228

Let's proceed to step 3:
If we divide 574 by 228, we get 2 and a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 456 from 574, we get 118.
Include the next digit (2) from the dividend after 118, then repeat: 1182 / 228

Advancing to step 4:
228 can be fit into 1182 5 times, resulting in a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 1140 away from 1182, we end up with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 228

Going ahead to step 5:
The number 228 fits into 421 1 times, leaving a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 251.0
Subtract 228 from 421 to get 193.
Take the next digit (2) from the dividend and append it to 193, then repeat: 1932 / 228

Going ahead to step 6:
When dividing 1932 by 228, we get 8 with a remainder of 108.
The next digit of our result is 8. 
Result so far: 2518.0
The remainder is 108 after subtracting 1824 from 1932.
Grab the next digit (6) from the dividend, add it to 108, then carry on: 1086 / 228

Step 7:
If we divide 1086 by 228, we get 4 and a remainder of 174.
Use 4 as the next digit of our solution. 
Result so far: 25184.0
Subtract 912 from 1086 to get 174.
Include the next digit (8) from the dividend after 174, then repeat: 1748 / 228

On to step 8:
The number 228 fits into 1748 7 times, leaving a remainder of 152.
Record the quotient 7 as the next digit in the result. 
Result so far: 251847.0
Subtracting 1596 from 1748 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 9:
1520 divided by 228 is 6 with a remainder of 152.
The next digit of our result is 6. 
Result so far: 251847.6
Subtract 1368 from 1520 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
1520 divided by 228 is 6 with a remainder of 152.
The next digit of our result is 6. 
Result so far: 251847.66
If we take 1368 away from 1520, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The quotient of the division is 251847.66, and the remainder is 0.152.
