We're dividing 25508085 by 511 
Let's see how many times 511 fits into 25508085.

Going ahead to step 1:
When dividing 2 by 511, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 511

Advancing to step 2:
If we divide 25 by 511, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 511

Going ahead to step 3:
511 goes into 255 0 times with a remainder of 255.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 255, we end up with 255.
Take the next digit (0) from the dividend and append it to 255, then repeat: 2550 / 511

Moving on to step 4:
When dividing 2550 by 511, we get 4 with a remainder of 506.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2044 from 2550, we get 506.
Append the next digit (8) from the dividend to 506 and continue with: 5068 / 511

Moving on to step 5:
When dividing 5068 by 511, we get 9 with a remainder of 469.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 4599 from 5068 to get 469.
Append the next digit (0) from the dividend to 469 and continue with: 4690 / 511

Moving on to step 6:
When dividing 4690 by 511, we get 9 with a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 499.0
Deduct 4599 from 4690 and we're left with 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 511

Moving on to step 7:
918 divided by 511 is 1 with a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 4991.0
The remainder is 407 after subtracting 511 from 918.
Take the next digit (5) from the dividend and append it to 407, then repeat: 4075 / 511

Moving on to step 8:
511 goes into 4075 7 times with a remainder of 498.
Write down 7 as next digit of the result. 
Result so far: 49917.0
If we subtract 3577 from 4075, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 9:
When dividing 4980 by 511, we get 9 with a remainder of 381.
The next digit of our result is 9. 
Result so far: 49917.9
If we take 4599 away from 4980, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 10:
511 can be fit into 3810 7 times, resulting in a remainder of 233.
The next digit of our result is 7. 
Result so far: 49917.97
Deduct 3577 from 3810 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 11:
2330 divided by 511 is 4 with a remainder of 286.
Record the quotient 4 as the next digit in the result. 
Result so far: 49917.974
If we take 2044 away from 2330, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 12:
If we divide 2860 by 511, we get 5 and a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 49917.9745
The remainder is 305 after subtracting 2555 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 13:
When dividing 3050 by 511, we get 5 with a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 49917.97455
Deduct 2555 from 3050 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The final outcome is 49917.97455, with a leftover of 0.000495.
