Let's divide 65133815 by 225
The aim is to understand the frequency of 225 in 65133815.

Let's proceed to step 1:
6 divided by 225 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 225

On to step 2:
When dividing 65 by 225, we get 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 225

On to step 3:
If we divide 651 by 225, we get 2 and a remainder of 201.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 450 from 651 and we're left with 201.
Take the next digit (3) from the dividend and append it to 201, then repeat: 2013 / 225

On to step 4:
When dividing 2013 by 225, we get 8 with a remainder of 213.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 1800 from 2013 and we're left with 213.
Bring next digit (3) of the dividend behind the 213 and repeat the process: 2133 / 225

Going ahead to step 5:
225 can be fit into 2133 9 times, resulting in a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 289.0
If we take 2025 away from 2133, we end up with 108.
Take the next digit (8) from the dividend and append it to 108, then repeat: 1088 / 225

Going ahead to step 6:
225 goes into 1088 4 times with a remainder of 188.
The next digit of our result is 4. 
Result so far: 2894.0
If we take 900 away from 1088, we end up with 188.
Append the next digit (1) from the dividend to 188 and continue with: 1881 / 225

Step 7:
1881 divided by 225 is 8 with a remainder of 81.
Record the quotient 8 as the next digit in the result. 
Result so far: 28948.0
Subtract 1800 from 1881 to get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 225

On to step 8:
The number 225 fits into 815 3 times, leaving a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 289483.0
If we subtract 675 from 815, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 9:
225 can be fit into 1400 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 289483.6
Subtract 1350 from 1400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 225, we get 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 289483.62
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
225 can be fit into 500 2 times, resulting in a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 289483.622
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 289483.622 and a remainder of 0.005.
