311020 ÷ 80 
We're looking to find how many times 80 goes into 311020.

Moving on to step 1:
3 divided by 80 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 80

Going ahead to step 2:
When dividing 31 by 80, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 80

Going ahead to step 3:
311 divided by 80 is 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 240 from 311 to get 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 80

Let's proceed to step 4:
If we divide 710 by 80, we get 8 and a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 70 after subtracting 640 from 710.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 80

On to step 5:
The number 80 fits into 702 8 times, leaving a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 388.0
The remainder is 62 after subtracting 640 from 702.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 80

Let's proceed to step 6:
If we divide 620 by 80, we get 7 and a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 3887.0
Subtract 560 from 620 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 3887.7
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.

Let's proceed to step 8:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3887.75
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:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3887.75
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.

Moving on to step 10:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3887.75
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.

The final result is 3887.75 with a remainder of 0.0.
