We look at the division of 387866 by 80 
We want to divide 387866 by 80.

Going ahead to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 80

Step 2:
80 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 80

On to step 3:
387 divided by 80 is 4 with a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 320 from 387 to get 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 80

On to step 4:
If we divide 678 by 80, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 640 from 678 to get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 80

Going ahead to step 5:
80 can be fit into 386 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
If we take 320 away from 386, we end up with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 80

Going ahead to step 6:
The number 80 fits into 666 8 times, leaving a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 4848.0
Subtracting 640 from 666 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
260 divided by 80 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 4848.3
The remainder is 20 after subtracting 240 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 4848.32
If we subtract 160 from 200, we 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.

Advancing to step 9:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4848.325
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.

Going ahead to step 10:
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: 4848.325
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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4848.325
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 4848.325, and the remainder is 0.0.
