We divide 25903878 by 9
Let's see how many times 9 fits into 25903878.

Moving on to step 1:
If we divide 2 by 9, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 9

Let's proceed to step 2:
If we divide 25 by 9, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 7 after subtracting 18 from 25.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 9

Step 3:
The number 9 fits into 79 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 72 from 79 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 9

Going ahead to step 4:
When dividing 70 by 9, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Subtracting 63 from 70 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 9

Step 5:
If we divide 73 by 9, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 2878.0
If we subtract 72 from 73, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 9

Advancing to step 6:
If we divide 18 by 9, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 28782.0
If we subtract 18 from 18, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 9

Moving on to step 7:
7 divided by 9 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 287820.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 9

Let's proceed to step 8:
78 divided by 9 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 2878208.0
Deduct 72 from 78 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 9 fits into 60 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 2878208.6
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
9 goes into 60 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2878208.66
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 2878208.66 and a remainder of 0.006.
