We divide 286446 by 80
We want to figure out the number of times 286446 can be divided by 80.

Advancing to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 80

On to step 2:
80 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 80

On to step 3:
If we divide 286 by 80, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 46 after subtracting 240 from 286.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 80

Moving on to step 4:
80 goes into 464 5 times with a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 400 away from 464, we end up with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 80

Moving on to step 5:
644 divided by 80 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 358.0
Subtract 640 from 644 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 80

Going ahead to step 6:
The number 80 fits into 46 0 times, leaving a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 3580.0
If we subtract 0 from 46, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
460 divided by 80 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 3580.5
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.
Write down 7 as next digit of the result. 
Result so far: 3580.57
Subtract 560 from 600 to get 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 9:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3580.575
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.

Let's proceed to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3580.575
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.

Going ahead to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3580.575
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.

After the division, we end up with 3580.575 and a remainder of 0.0.
