25940045 ÷ 680 
Our goal is to divide 25940045 by 680.

Advancing to step 1:
680 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 680

On to step 2:
680 can be fit into 25 0 times, resulting in 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 / 680

Step 3:
680 can be fit into 259 0 times, resulting in a remainder of 259.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 259 to get 259.
Take the next digit (4) from the dividend and append it to 259, then repeat: 2594 / 680

Let's proceed to step 4:
If we divide 2594 by 680, we get 3 and a remainder of 554.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2040 from 2594 and we're left with 554.
Grab the next digit (0) from the dividend, add it to 554, then carry on: 5540 / 680

Step 5:
5540 divided by 680 is 8 with a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 5440 from 5540 leaves us with 100.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 680

Step 6:
680 goes into 1000 1 times with a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 381.0
If we take 680 away from 1000, we end up with 320.
Append the next digit (4) from the dividend to 320 and continue with: 3204 / 680

On to step 7:
680 goes into 3204 4 times with a remainder of 484.
Write down 4 as next digit of the result. 
Result so far: 3814.0
If we subtract 2720 from 3204, we get 484.
Include the next digit (5) from the dividend after 484, then repeat: 4845 / 680

Going ahead to step 8:
If we divide 4845 by 680, we get 7 and a remainder of 85.
Write down 7 as next digit of the result. 
Result so far: 38147.0
Subtracting 4760 from 4845 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
680 goes into 850 1 times with a remainder of 170.
The number 1 becomes the next digit in our result. 
Result so far: 38147.1
Subtract 680 from 850 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
1700 divided by 680 is 2 with a remainder of 340.
Record the quotient 2 as the next digit in the result. 
Result so far: 38147.12
If we subtract 1360 from 1700, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
If we divide 3400 by 680, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 38147.125
Subtract 3400 from 3400 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.

Let's proceed to step 12:
When dividing 0 by 680, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38147.125
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.

Advancing to step 13:
680 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 38147.125
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 38147.125 with a remainder of 0.0.
