Let's divide 25805869 by 10
Our goal is to divide 25805869 by 10.

Advancing to step 1:
The number 10 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 10

On to step 2:
If we divide 25 by 10, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 20 from 25 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 10

Let's proceed to step 3:
10 goes into 58 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 8 after subtracting 50 from 58.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 10

Moving on to step 4:
When dividing 80 by 10, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 258.0
If we subtract 80 from 80, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 10

Moving on to step 5:
5 divided by 10 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 2580.0
Subtract 0 from 5 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 10

Let's proceed to step 6:
If we divide 58 by 10, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 25805.0
If we take 50 away from 58, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 10

Step 7:
10 can be fit into 86 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 258058.0
Subtracting 80 from 86 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 10

Advancing to step 8:
10 goes into 69 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 2580586.0
Subtract 60 from 69 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
90 divided by 10 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2580586.9
Deduct 90 from 90 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.

Advancing to step 10:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2580586.9
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.

Advancing to step 11:
If we divide 0 by 10, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2580586.9
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 2580586.9 with a remainder of 0.0.
