Let's divide 310065 by 80
Let's see how many times 80 fits into 310065.

On to step 1:
80 goes into 3 0 times 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.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 80

Moving on to step 2:
When dividing 31 by 80, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 80

Advancing to step 3:
80 goes into 310 3 times with a remainder of 70.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 240 from 310 leaves us with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 80

Moving on to step 4:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 38.0
The remainder is 60 after subtracting 640 from 700.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 80

On to step 5:
If we divide 606 by 80, we get 7 and a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
Deduct 560 from 606 and we're left with 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 80

Going ahead to step 6:
If we divide 465 by 80, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3875.0
If we take 400 away from 465, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
650 divided by 80 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 3875.8
Deduct 640 from 650 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 3875.81
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 3875.812
Deduct 160 from 200 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 10:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3875.8125
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.

Advancing 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: 3875.8125
Subtract 0 from 0 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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3875.8125
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 3875.8125 with a remainder of 0.0.
