Let's divide 257646 by 80
We want to figure out the number of times 257646 can be divided by 80.

Let's proceed to step 1:
The number 80 fits into 2 0 times, leaving 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 / 80

Let's proceed to step 2:
The number 80 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 80

Going ahead to step 3:
If we divide 257 by 80, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 240 from 257 and we're left with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 80

On to step 4:
When dividing 176 by 80, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 160 from 176 to get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 80

Moving on to step 5:
164 divided by 80 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 322.0
If we take 160 away from 164, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 80

Going ahead to step 6:
When dividing 46 by 80, we get 0 with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 3220.0
The remainder is 46 after subtracting 0 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
80 goes into 460 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 3220.5
Subtract 400 from 460 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 3220.57
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3220.575
If we subtract 400 from 400, 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.

Going ahead to step 10:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3220.575
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.

Going ahead to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3220.575
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 3220.575, and the remainder is 0.0.
