301815 ÷ 225 
We want to divide 301815 by 225.

Step 1:
225 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 225

Advancing to step 2:
30 divided by 225 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 225

Let's proceed to step 3:
301 divided by 225 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 225 from 301, we get 76.
Take the next digit (8) from the dividend and append it to 76, then repeat: 768 / 225

On to step 4:
225 goes into 768 3 times with a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 93 after subtracting 675 from 768.
Take the next digit (1) from the dividend and append it to 93, then repeat: 931 / 225

Advancing to step 5:
If we divide 931 by 225, we get 4 and a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtract 900 from 931 to get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 225

Advancing to step 6:
The number 225 fits into 315 1 times, leaving a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 1341.0
If we subtract 225 from 315, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 7:
When dividing 900 by 225, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1341.4
If we subtract 900 from 900, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
225 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1341.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
225 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1341.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1341.4 and a remainder of 0.0.
