81654108 ÷ 225 
We want to figure out the number of times 81654108 can be divided by 225.

Moving on to step 1:
225 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 225

On to step 2:
If we divide 81 by 225, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 225

Advancing to step 3:
If we divide 816 by 225, we get 3 and a remainder of 141.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 141 after subtracting 675 from 816.
Append the next digit (5) from the dividend to 141 and continue with: 1415 / 225

On to step 4:
If we divide 1415 by 225, we get 6 and a remainder of 65.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 65 after subtracting 1350 from 1415.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 225

Let's proceed to step 5:
225 goes into 654 2 times with a remainder of 204.
The next digit of our result is 2. 
Result so far: 362.0
If we take 450 away from 654, we end up with 204.
Include the next digit (1) from the dividend after 204, then repeat: 2041 / 225

Moving on to step 6:
The number 225 fits into 2041 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 3629.0
Subtracting 2025 from 2041 leaves us with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 225

Moving on to step 7:
225 can be fit into 160 0 times, resulting in a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 36290.0
The remainder is 160 after subtracting 0 from 160.
Include the next digit (8) from the dividend after 160, then repeat: 1608 / 225

Let's proceed to step 8:
225 goes into 1608 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 362907.0
If we take 1575 away from 1608, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
225 can be fit into 330 1 times, resulting in a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 362907.1
Subtracting 225 from 330 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 10:
1050 divided by 225 is 4 with a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 362907.14
Subtract 900 from 1050 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
225 can be fit into 1500 6 times, resulting in a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 362907.146
Deduct 1350 from 1500 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
225 can be fit into 1500 6 times, resulting in a remainder of 150.
Write down 6 as next digit of the result. 
Result so far: 362907.1466
Subtracting 1350 from 1500 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 362907.1466 with a remainder of 0.0015.
