508142 divided by 25 
Our goal is to divide 508142 by 25.

Going ahead to step 1:
25 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 25

Moving on to step 2:
If we divide 50 by 25, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 50 from 50, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 25

Moving on to step 3:
25 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 25

Going ahead to step 4:
25 can be fit into 81 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
If we take 75 away from 81, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 25

Advancing to step 5:
64 divided by 25 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2032.0
The remainder is 14 after subtracting 50 from 64.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 25

Advancing to step 6:
142 divided by 25 is 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 20325.0
Deduct 125 from 142 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 25, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 20325.6
Subtracting 150 from 170 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 25 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 20325.68
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20325.68
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 20325.68
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 20325.68, with a leftover of 0.0.
