Let's divide 28946590 by 225
The aim is to understand the frequency of 225 in 28946590.

Step 1:
225 can be fit into 2 0 times, resulting in 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.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 225

Going ahead to step 2:
225 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 225

Going ahead to step 3:
225 goes into 289 1 times with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 225 from 289 and we're left with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 225

Step 4:
644 divided by 225 is 2 with a remainder of 194.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 450 from 644 and we're left with 194.
Fetch the next digit (6) from the dividend, attach it to 194 and continue: 1946 / 225

Going ahead to step 5:
If we divide 1946 by 225, we get 8 and a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 128.0
Subtracting 1800 from 1946 leaves us with 146.
Take the next digit (5) from the dividend and append it to 146, then repeat: 1465 / 225

Let's proceed to step 6:
1465 divided by 225 is 6 with a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 1286.0
Subtracting 1350 from 1465 leaves us with 115.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 225

Moving on to step 7:
1159 divided by 225 is 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 12865.0
Subtracting 1125 from 1159 leaves us with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 225

Moving on to step 8:
The number 225 fits into 340 1 times, leaving a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 128651.0
If we subtract 225 from 340, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
225 can be fit into 1150 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 128651.5
Subtracting 1125 from 1150 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
The number 225 fits into 250 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 128651.51
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
250 divided by 225 is 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 128651.511
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 128651.511 and a remainder of 0.0025.
