We divide 28878319 by 225
The aim is to understand the frequency of 225 in 28878319.

Step 1:
If we divide 2 by 225, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 225

Going ahead to step 2:
If we divide 28 by 225, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 225

Going ahead to step 3:
When dividing 288 by 225, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 63 after subtracting 225 from 288.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 225

Going ahead to step 4:
225 can be fit into 637 2 times, resulting in a remainder of 187.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 450 from 637 and we're left with 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 225

Let's proceed to step 5:
1878 divided by 225 is 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 128.0
If we take 1800 away from 1878, we end up with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 225

Let's proceed to step 6:
The number 225 fits into 783 3 times, leaving a remainder of 108.
Put 3 as the next digit of the answer. 
Result so far: 1283.0
Subtract 675 from 783 to get 108.
Include the next digit (1) from the dividend after 108, then repeat: 1081 / 225

Step 7:
If we divide 1081 by 225, we get 4 and a remainder of 181.
The number 4 becomes the next digit in our result. 
Result so far: 12834.0
Subtracting 900 from 1081 leaves us with 181.
Take the next digit (9) from the dividend and append it to 181, then repeat: 1819 / 225

Let's proceed to step 8:
225 can be fit into 1819 8 times, resulting in a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 128348.0
Subtract 1800 from 1819 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
225 can be fit into 190 0 times, resulting in a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 128348.0
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
225 can be fit into 1900 8 times, resulting in a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 128348.08
Subtract 1800 from 1900 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.

Advancing to step 11:
225 can be fit into 1000 4 times, resulting in a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 128348.084
If we subtract 900 from 1000, we 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.

Let's proceed to step 12:
When dividing 1000 by 225, we get 4 with a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 128348.0844
If we subtract 900 from 1000, we 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.

Our division results in 128348.0844 with a remaining 0.001.
