We're dividing 321671 by 80 
Let's see how many times 80 fits into 321671.

Moving on to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 80

Going ahead to step 2:
When dividing 32 by 80, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 80

Going ahead to step 3:
The number 80 fits into 321 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 320 from 321, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 80

Step 4:
When dividing 16 by 80, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 80

Let's proceed to step 5:
80 can be fit into 167 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 402.0
Subtract 160 from 167 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 80

Advancing to step 6:
The number 80 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 4020.0
If we subtract 0 from 71, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
80 can be fit into 710 8 times, resulting in a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 4020.8
If we take 640 away from 710, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 4020.88
Subtracting 640 from 700 leaves us 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.

Our division results in 4020.88 with a remaining 0.06.
