25128089 ÷ 285 
Let's see how many times 285 fits into 25128089.

Moving on to step 1:
285 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 285

Advancing to step 2:
When dividing 25 by 285, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 285

On to step 3:
If we divide 251 by 285, we get 0 and a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 251, we end up with 251.
Bring next digit (2) of the dividend behind the 251 and repeat the process: 2512 / 285

On to step 4:
The number 285 fits into 2512 8 times, leaving a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 2280 from 2512 and we're left with 232.
Include the next digit (8) from the dividend after 232, then repeat: 2328 / 285

Going ahead to step 5:
When dividing 2328 by 285, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtracting 2280 from 2328 leaves us with 48.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 285

Going ahead to step 6:
When dividing 480 by 285, we get 1 with a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 881.0
Subtract 285 from 480 to get 195.
Take the next digit (8) from the dividend and append it to 195, then repeat: 1958 / 285

Going ahead to step 7:
If we divide 1958 by 285, we get 6 and a remainder of 248.
Write down 6 as next digit of the result. 
Result so far: 8816.0
Deduct 1710 from 1958 and we're left with 248.
Fetch the next digit (9) from the dividend, attach it to 248 and continue: 2489 / 285

On to step 8:
2489 divided by 285 is 8 with a remainder of 209.
Write down 8 as next digit of the result. 
Result so far: 88168.0
Deduct 2280 from 2489 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
2090 divided by 285 is 7 with a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 88168.7
Subtract 1995 from 2090 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 10:
950 divided by 285 is 3 with a remainder of 95.
The next digit of our result is 3. 
Result so far: 88168.73
Subtract 855 from 950 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 11:
285 goes into 950 3 times with a remainder of 95.
Write down 3 as next digit of the result. 
Result so far: 88168.733
Subtract 855 from 950 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Our division results in 88168.733 with a remaining 0.0095.
