Let's divide 82016648 by 80
We want to figure out the number of times 82016648 can be divided by 80.

Moving on to step 1:
8 divided by 80 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 80

Moving on to step 2:
The number 80 fits into 82 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 82 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 80

Moving on to step 3:
20 divided by 80 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 20, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 80

On to step 4:
If we divide 201 by 80, we get 2 and a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we subtract 160 from 201, we get 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 80

Advancing to step 5:
80 can be fit into 416 5 times, resulting in a remainder of 16.
The next digit of our result is 5. 
Result so far: 1025.0
Subtract 400 from 416 to get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 80

Step 6:
The number 80 fits into 166 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 10252.0
If we subtract 160 from 166, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 80

Step 7:
80 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 102520.0
If we take 0 away from 64, we end up with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 80

Advancing to step 8:
80 can be fit into 648 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1025208.0
If we subtract 640 from 648, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 goes into 80 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1025208.1
If we subtract 80 from 80, 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 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1025208.1
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.

On to step 11:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1025208.1
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.

After the division, we end up with 1025208.1 and a remainder of 0.0.
