We're dividing 65144217 by 225 
Our goal is to divide 65144217 by 225.

Let's proceed to step 1:
The number 225 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 225

On to step 2:
225 goes into 65 0 times 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.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 225

Let's proceed to step 3:
225 goes into 651 2 times with a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 450 from 651 to get 201.
Grab the next digit (4) from the dividend, add it to 201, then carry on: 2014 / 225

Moving on to step 4:
225 goes into 2014 8 times with a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 1800 from 2014 to get 214.
Grab the next digit (4) from the dividend, add it to 214, then carry on: 2144 / 225

Going ahead to step 5:
2144 divided by 225 is 9 with a remainder of 119.
The next digit of our result is 9. 
Result so far: 289.0
If we take 2025 away from 2144, we end up with 119.
Include the next digit (2) from the dividend after 119, then repeat: 1192 / 225

Step 6:
225 goes into 1192 5 times with a remainder of 67.
Put 5 as the next digit of the answer. 
Result so far: 2895.0
The remainder is 67 after subtracting 1125 from 1192.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 225

On to step 7:
671 divided by 225 is 2 with a remainder of 221.
Record the quotient 2 as the next digit in the result. 
Result so far: 28952.0
Deduct 450 from 671 and we're left with 221.
Fetch the next digit (7) from the dividend, attach it to 221 and continue: 2217 / 225

Step 8:
225 can be fit into 2217 9 times, resulting in a remainder of 192.
Put 9 as the next digit of the answer. 
Result so far: 289529.0
Deduct 2025 from 2217 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 9:
When dividing 1920 by 225, we get 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 289529.8
Deduct 1800 from 1920 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
1200 divided by 225 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 289529.85
If we subtract 1125 from 1200, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
The number 225 fits into 750 3 times, leaving a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 289529.853
If we take 675 away from 750, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
The number 225 fits into 750 3 times, leaving a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 289529.8533
If we subtract 675 from 750, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 289529.8533 with a remainder of 0.00075.
