25655565 ÷ 80 
We want to figure out the number of times 25655565 can be divided by 80.

Let's proceed to step 1:
80 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 80

Advancing to step 2:
The number 80 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 80

Let's proceed to step 3:
80 goes into 256 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 240 away from 256, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 80

Going ahead to step 4:
80 goes into 165 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 160 from 165 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 80

Moving on to step 5:
55 divided by 80 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 320.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 80

Step 6:
80 goes into 555 6 times with a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 3206.0
If we subtract 480 from 555, we get 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 80

Step 7:
When dividing 756 by 80, we get 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 32069.0
If we subtract 720 from 756, we get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 80

On to step 8:
80 goes into 365 4 times with a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 320694.0
The remainder is 45 after subtracting 320 from 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
If we divide 450 by 80, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 320694.5
If we subtract 400 from 450, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
80 goes into 500 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 320694.56
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 320694.562
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 320694.5625
If we take 400 away from 400, we end up with 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:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 320694.5625
If we take 0 away from 0, we end up with 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 14:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 320694.5625
The remainder is 0 after subtracting 0 from 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 320694.5625 with a remainder of 0.0.
