Let's divide 25518318 by 227
The aim is to understand the frequency of 227 in 25518318.

Advancing to step 1:
The number 227 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 227

Advancing to step 2:
25 divided by 227 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 227

Going ahead to step 3:
The number 227 fits into 255 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 227 from 255 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 227

Let's proceed to step 4:
The number 227 fits into 281 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 54 after subtracting 227 from 281.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 227

Going ahead to step 5:
The number 227 fits into 548 2 times, leaving a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we subtract 454 from 548, we get 94.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 227

Let's proceed to step 6:
227 goes into 943 4 times with a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 1124.0
If we subtract 908 from 943, we get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 227

Moving on to step 7:
227 goes into 351 1 times with a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 11241.0
If we take 227 away from 351, we end up with 124.
Include the next digit (8) from the dividend after 124, then repeat: 1248 / 227

Moving on to step 8:
If we divide 1248 by 227, we get 5 and a remainder of 113.
The next digit of our result is 5. 
Result so far: 112415.0
If we take 1135 away from 1248, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 9:
When dividing 1130 by 227, we get 4 with a remainder of 222.
The next digit of our result is 4. 
Result so far: 112415.4
Subtracting 908 from 1130 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 10:
227 can be fit into 2220 9 times, resulting in a remainder of 177.
Write down 9 as next digit of the result. 
Result so far: 112415.49
If we subtract 2043 from 2220, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 11:
When dividing 1770 by 227, we get 7 with a remainder of 181.
Record the quotient 7 as the next digit in the result. 
Result so far: 112415.497
If we take 1589 away from 1770, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 12:
If we divide 1810 by 227, we get 7 and a remainder of 221.
Write down 7 as next digit of the result. 
Result so far: 112415.4977
Subtracting 1589 from 1810 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

After the division, we end up with 112415.4977 and a remainder of 0.00221.
