Let's divide 321020 by 80
We want to figure out the number of times 321020 can be divided by 80.

Let's proceed to step 1:
When dividing 3 by 80, we get 0 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.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 80

Moving on to step 2:
32 divided by 80 is 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 80

Step 3:
80 goes into 321 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 320 away from 321, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 80

Moving on to step 4:
10 divided by 80 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 10, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 80

Moving on to step 5:
102 divided by 80 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 401.0
If we take 80 away from 102, we end up with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 80

Step 6:
When dividing 220 by 80, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 4012.0
The remainder is 60 after subtracting 160 from 220.
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 7:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 4012.7
Subtract 560 from 600 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.

On to step 8:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4012.75
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.

Going ahead to step 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4012.75
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.

Let's proceed to step 10:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4012.75
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.

After the division, we end up with 4012.75 and a remainder of 0.0.
