We're dividing 505612 by 25 
We're looking to find how many times 25 goes into 505612.

Advancing to step 1:
When dividing 5 by 25, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 25

Advancing to step 2:
25 goes into 50 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 50 from 50, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 25

Advancing to step 3:
The number 25 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 25

Let's proceed to step 4:
If we divide 56 by 25, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 202.0
Subtract 50 from 56 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 25

Step 5:
61 divided by 25 is 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2022.0
Subtract 50 from 61 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 25

Step 6:
When dividing 112 by 25, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 20224.0
Subtract 100 from 112 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 25 fits into 120 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 20224.4
Subtracting 100 from 120 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.

On to step 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 20224.48
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.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20224.48
If we subtract 0 from 0, 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.

Going ahead to step 10:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20224.48
Subtract 0 from 0 to 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.

The final result is 20224.48 with a remainder of 0.0.
