Let's divide 25565297 by 780
We want to figure out the number of times 25565297 can be divided by 780.

Let's proceed to step 1:
780 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 780

On to step 2:
The number 780 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 780

Let's proceed to step 3:
The number 780 fits into 255 0 times, leaving a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 255, we end up with 255.
Append the next digit (6) from the dividend to 255 and continue with: 2556 / 780

Going ahead to step 4:
If we divide 2556 by 780, we get 3 and a remainder of 216.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2340 away from 2556, we end up with 216.
Grab the next digit (5) from the dividend, add it to 216, then carry on: 2165 / 780

On to step 5:
780 goes into 2165 2 times with a remainder of 605.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 1560 away from 2165, we end up with 605.
Append the next digit (2) from the dividend to 605 and continue with: 6052 / 780

Going ahead to step 6:
The number 780 fits into 6052 7 times, leaving a remainder of 592.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
If we subtract 5460 from 6052, we get 592.
Append the next digit (9) from the dividend to 592 and continue with: 5929 / 780

Moving on to step 7:
If we divide 5929 by 780, we get 7 and a remainder of 469.
Put 7 as the next digit of the answer. 
Result so far: 3277.0
If we take 5460 away from 5929, we end up with 469.
Take the next digit (7) from the dividend and append it to 469, then repeat: 4697 / 780

On to step 8:
If we divide 4697 by 780, we get 6 and a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 32776.0
If we subtract 4680 from 4697, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
The number 780 fits into 170 0 times, leaving a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 32776.0
Deduct 0 from 170 and we're left with 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:
If we divide 1700 by 780, we get 2 and a remainder of 140.
The next digit of our result is 2. 
Result so far: 32776.02
Subtract 1560 from 1700 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
The number 780 fits into 1400 1 times, leaving a remainder of 620.
The number 1 becomes the next digit in our result. 
Result so far: 32776.021
Subtracting 780 from 1400 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 12:
6200 divided by 780 is 7 with a remainder of 740.
The number 7 becomes the next digit in our result. 
Result so far: 32776.0217
Subtracting 5460 from 6200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 13:
7400 divided by 780 is 9 with a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 32776.02179
Subtract 7020 from 7400 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
If we divide 3800 by 780, we get 4 and a remainder of 680.
Record the quotient 4 as the next digit in the result. 
Result so far: 32776.021794
If we subtract 3120 from 3800, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 15:
6800 divided by 780 is 8 with a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 32776.0217948
If we take 6240 away from 6800, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
780 can be fit into 5600 7 times, resulting in a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 32776.02179487
If we take 5460 away from 5600, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 32776.02179487, and the remainder is 1.4e-07.
