25433953 ÷ 781 
We want to figure out the number of times 25433953 can be divided by 781.

On to step 1:
The number 781 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 781

Advancing to step 2:
781 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 781

On to step 3:
781 goes into 254 0 times with a remainder of 254.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 254, we get 254.
Bring next digit (3) of the dividend behind the 254 and repeat the process: 2543 / 781

On to step 4:
When dividing 2543 by 781, we get 3 with a remainder of 200.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2343 from 2543, we get 200.
Grab the next digit (3) from the dividend, add it to 200, then carry on: 2003 / 781

Step 5:
781 can be fit into 2003 2 times, resulting in a remainder of 441.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtracting 1562 from 2003 leaves us with 441.
Include the next digit (9) from the dividend after 441, then repeat: 4419 / 781

Advancing to step 6:
The number 781 fits into 4419 5 times, leaving a remainder of 514.
Write down 5 as next digit of the result. 
Result so far: 325.0
If we subtract 3905 from 4419, we get 514.
Grab the next digit (5) from the dividend, add it to 514, then carry on: 5145 / 781

Let's proceed to step 7:
5145 divided by 781 is 6 with a remainder of 459.
Record the quotient 6 as the next digit in the result. 
Result so far: 3256.0
Subtracting 4686 from 5145 leaves us with 459.
Fetch the next digit (3) from the dividend, attach it to 459 and continue: 4593 / 781

Advancing to step 8:
If we divide 4593 by 781, we get 5 and a remainder of 688.
Use 5 as the next digit of our solution. 
Result so far: 32565.0
Deduct 3905 from 4593 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 9:
When dividing 6880 by 781, we get 8 with a remainder of 632.
Use 8 as the next digit of our solution. 
Result so far: 32565.8
If we subtract 6248 from 6880, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 10:
The number 781 fits into 6320 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 32565.88
If we take 6248 away from 6320, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 32565.88 with a remainder of 0.072.
