We're dividing 87577584 by 225 
Let's see how many times 225 fits into 87577584.

Going ahead to step 1:
225 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 225

Step 2:
225 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (5) from the dividend to 87 and continue with: 875 / 225

Going ahead to step 3:
225 goes into 875 3 times with a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 675 away from 875, we end up with 200.
Append the next digit (7) from the dividend to 200 and continue with: 2007 / 225

Going ahead to step 4:
The number 225 fits into 2007 8 times, leaving a remainder of 207.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 1800 from 2007 to get 207.
Append the next digit (7) from the dividend to 207 and continue with: 2077 / 225

Let's proceed to step 5:
The number 225 fits into 2077 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 389.0
Subtract 2025 from 2077 to get 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 225

On to step 6:
If we divide 525 by 225, we get 2 and a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 3892.0
Deduct 450 from 525 and we're left with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 225

Advancing to step 7:
225 goes into 758 3 times with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 38923.0
If we subtract 675 from 758, we get 83.
Grab the next digit (4) from the dividend, add it to 83, then carry on: 834 / 225

Going ahead to step 8:
The number 225 fits into 834 3 times, leaving a remainder of 159.
The number 3 becomes the next digit in our result. 
Result so far: 389233.0
If we subtract 675 from 834, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 9:
If we divide 1590 by 225, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 389233.7
If we take 1575 away from 1590, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
When dividing 150 by 225, we get 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 389233.7
If we subtract 0 from 150, we 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:
If we divide 1500 by 225, we get 6 and a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 389233.706
Subtract 1350 from 1500 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.

Moving on to step 12:
225 goes into 1500 6 times with a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 389233.7066
If we take 1350 away from 1500, we end up 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.

After the division, we end up with 389233.7066 and a remainder of 0.0015.
