We divide 99875680 by 225
We want to divide 99875680 by 225.

Going ahead to step 1:
225 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 225

Step 2:
225 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Include the next digit (8) from the dividend after 99, then repeat: 998 / 225

Step 3:
The number 225 fits into 998 4 times, leaving a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 900 from 998 and we're left with 98.
Fetch the next digit (7) from the dividend, attach it to 98 and continue: 987 / 225

Moving on to step 4:
987 divided by 225 is 4 with a remainder of 87.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 900 from 987 leaves us with 87.
Fetch the next digit (5) from the dividend, attach it to 87 and continue: 875 / 225

Moving on to step 5:
The number 225 fits into 875 3 times, leaving a remainder of 200.
Write down 3 as next digit of the result. 
Result so far: 443.0
If we subtract 675 from 875, we get 200.
Grab the next digit (6) from the dividend, add it to 200, then carry on: 2006 / 225

Step 6:
The number 225 fits into 2006 8 times, leaving a remainder of 206.
The next digit of our result is 8. 
Result so far: 4438.0
Deduct 1800 from 2006 and we're left with 206.
Fetch the next digit (8) from the dividend, attach it to 206 and continue: 2068 / 225

Going ahead to step 7:
225 can be fit into 2068 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 44389.0
Subtracting 2025 from 2068 leaves us with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 225

Moving on to step 8:
When dividing 430 by 225, we get 1 with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 443891.0
The remainder is 205 after subtracting 225 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
225 goes into 2050 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 443891.9
If we subtract 2025 from 2050, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
When dividing 250 by 225, we get 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 443891.91
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
When dividing 250 by 225, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 443891.911
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 443891.911 with a remainder of 0.0025.
