We're dividing 25131418 by 506 
Let's see how many times 506 fits into 25131418.

Advancing to step 1:
506 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
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 / 506

Step 2:
When dividing 25 by 506, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 506

Advancing to step 3:
251 divided by 506 is 0 with a remainder of 251.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 251, we get 251.
Take the next digit (3) from the dividend and append it to 251, then repeat: 2513 / 506

On to step 4:
2513 divided by 506 is 4 with a remainder of 489.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2024 from 2513, we get 489.
Append the next digit (1) from the dividend to 489 and continue with: 4891 / 506

Advancing to step 5:
506 goes into 4891 9 times with a remainder of 337.
Write down 9 as next digit of the result. 
Result so far: 49.0
The remainder is 337 after subtracting 4554 from 4891.
Append the next digit (4) from the dividend to 337 and continue with: 3374 / 506

Advancing to step 6:
If we divide 3374 by 506, we get 6 and a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 496.0
Subtract 3036 from 3374 to get 338.
Take the next digit (1) from the dividend and append it to 338, then repeat: 3381 / 506

On to step 7:
When dividing 3381 by 506, we get 6 with a remainder of 345.
Use 6 as the next digit of our solution. 
Result so far: 4966.0
Subtracting 3036 from 3381 leaves us with 345.
Append the next digit (8) from the dividend to 345 and continue with: 3458 / 506

Moving on to step 8:
506 can be fit into 3458 6 times, resulting in a remainder of 422.
Put 6 as the next digit of the answer. 
Result so far: 49666.0
The remainder is 422 after subtracting 3036 from 3458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 9:
The number 506 fits into 4220 8 times, leaving a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 49666.8
The remainder is 172 after subtracting 4048 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 10:
1720 divided by 506 is 3 with a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 49666.83
The remainder is 202 after subtracting 1518 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 11:
When dividing 2020 by 506, we get 3 with a remainder of 502.
The next digit of our result is 3. 
Result so far: 49666.833
If we subtract 1518 from 2020, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Our division results in 49666.833 with a remaining 0.0502.
