We look at the division of 389934 by 80 
We want to divide 389934 by 80.

On to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 80

Step 2:
When dividing 38 by 80, we get 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 80

Advancing to step 3:
389 divided by 80 is 4 with a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 320 from 389 to get 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 80

Advancing to step 4:
If we divide 699 by 80, we get 8 and a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we subtract 640 from 699, we get 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 80

Step 5:
80 goes into 593 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 487.0
If we subtract 560 from 593, we get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 80

On to step 6:
80 can be fit into 334 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4874.0
Subtract 320 from 334 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
80 can be fit into 140 1 times, resulting in a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 4874.1
The remainder is 60 after subtracting 80 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 4874.17
If we take 560 away from 600, we end up 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.

Let's proceed to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4874.175
Subtract 400 from 400 to 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:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4874.175
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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4874.175
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.

Our division results in 4874.175 with a remaining 0.0.
