We divide 396100 by 80
We want to figure out the number of times 396100 can be divided by 80.

Moving on to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 80

On to step 2:
39 divided by 80 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 80

Let's proceed to step 3:
80 can be fit into 396 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 76 after subtracting 320 from 396.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 80

Moving on to step 4:
The number 80 fits into 761 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 41 after subtracting 720 from 761.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 80

Step 5:
When dividing 410 by 80, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 495.0
If we subtract 400 from 410, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 80

On to step 6:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 4951.0
Deduct 80 from 100 and we're left with 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 7:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 4951.2
Subtracting 160 from 200 leaves us 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.

Step 8:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4951.25
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.

Let's proceed to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4951.25
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.

Step 10:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4951.25
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 final result is 4951.25 with a remainder of 0.0.
