Let's divide 286386 by 80
We want to figure out the number of times 286386 can be divided by 80.

Going ahead to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 80

Advancing to step 2:
When dividing 28 by 80, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 80

On to step 3:
The number 80 fits into 286 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 240 from 286 to get 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 80

Let's proceed to step 4:
If we divide 463 by 80, we get 5 and a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtracting 400 from 463 leaves us with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 80

Let's proceed to step 5:
When dividing 638 by 80, we get 7 with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 357.0
Subtracting 560 from 638 leaves us with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 80

Advancing to step 6:
80 goes into 786 9 times with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 3579.0
The remainder is 66 after subtracting 720 from 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
When dividing 660 by 80, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 3579.8
Deduct 640 from 660 and we're left 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 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 3579.82
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 3579.825
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.

Advancing to step 10:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3579.825
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.

On to step 11:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3579.825
Deduct 0 from 0 and we're left 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 3579.825, and the remainder is 0.0.
