25980487 ÷ 902 
Our goal is to divide 25980487 by 902.

Moving on to step 1:
When dividing 2 by 902, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 902

Step 2:
When dividing 25 by 902, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 902

Let's proceed to step 3:
259 divided by 902 is 0 with a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 259 to get 259.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 902

Step 4:
2598 divided by 902 is 2 with a remainder of 794.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 794 after subtracting 1804 from 2598.
Take the next digit (0) from the dividend and append it to 794, then repeat: 7940 / 902

Let's proceed to step 5:
When dividing 7940 by 902, we get 8 with a remainder of 724.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 7216 from 7940 and we're left with 724.
Append the next digit (4) from the dividend to 724 and continue with: 7244 / 902

Let's proceed to step 6:
902 can be fit into 7244 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
The remainder is 28 after subtracting 7216 from 7244.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 902

Moving on to step 7:
When dividing 288 by 902, we get 0 with a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 2880.0
If we subtract 0 from 288, we get 288.
Grab the next digit (7) from the dividend, add it to 288, then carry on: 2887 / 902

Step 8:
The number 902 fits into 2887 3 times, leaving a remainder of 181.
Put 3 as the next digit of the answer. 
Result so far: 28803.0
If we take 2706 away from 2887, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 9:
The number 902 fits into 1810 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 28803.2
Deduct 1804 from 1810 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.

Advancing to step 10:
902 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 28803.2
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
When dividing 600 by 902, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 28803.2
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 28803.2, and the remainder is 0.06.
