We divide 393353 by 80
Our goal is to divide 393353 by 80.

Advancing to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 80

Moving on to step 2:
80 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 80

Step 3:
The number 80 fits into 393 4 times, leaving a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 320 from 393 to get 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 80

Let's proceed to step 4:
80 goes into 733 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 720 away from 733, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 80

On to step 5:
The number 80 fits into 135 1 times, leaving a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 491.0
Subtracting 80 from 135 leaves us with 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 80

Step 6:
80 goes into 553 6 times with a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 4916.0
If we take 480 away from 553, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
80 can be fit into 730 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 4916.9
The remainder is 10 after subtracting 720 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
80 goes into 100 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 4916.91
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 4916.912
Subtract 160 from 200 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 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4916.9125
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.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4916.9125
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.

Let's proceed to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4916.9125
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.

Our division results in 4916.9125 with a remaining 0.0.
