392811 divided by 80 
We want to figure out the number of times 392811 can be divided by 80.

Moving on to step 1:
3 divided by 80 is 0 with 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.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 80

Going ahead to step 2:
When dividing 39 by 80, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 80

Step 3:
When dividing 392 by 80, we get 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 320 from 392 leaves us with 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 80

Advancing to step 4:
80 can be fit into 728 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 720 from 728 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 80

Step 5:
80 can be fit into 81 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 491.0
Subtracting 80 from 81 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 80

Let's proceed to step 6:
If we divide 11 by 80, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 4910.0
If we take 0 away from 11, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 80, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 4910.1
Subtracting 80 from 110 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 4910.13
If we take 240 away from 300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 goes into 600 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 4910.137
Deduct 560 from 600 and we're left 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.

Advancing 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: 4910.1375
Subtracting 400 from 400 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:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4910.1375
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.

Let's proceed to step 12:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4910.1375
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.

Our division results in 4910.1375 with a remaining 0.0.
