393602 divided by 80 
We want to figure out the number of times 393602 can be divided by 80.

On to step 1:
80 goes into 3 0 times with 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.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 80

On to step 2:
When dividing 39 by 80, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 80

Step 3:
80 can be fit into 393 4 times, resulting in a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 320 from 393 and we're left with 73.
Take the next digit (6) from the dividend and append it to 73, then repeat: 736 / 80

Moving on to step 4:
If we divide 736 by 80, we get 9 and a remainder of 16.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 720 from 736 to get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 80

On to step 5:
80 goes into 160 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 492.0
If we take 160 away from 160, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 80

Let's proceed to step 6:
The number 80 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 4920.0
If we take 0 away from 2, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
80 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4920.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
80 goes into 200 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 4920.02
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.

Advancing to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4920.025
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4920.025
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.

Step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4920.025
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.

The quotient of the division is 4920.025, and the remainder is 0.0.
