Let's divide 305665 by 80
We're looking to find how many times 80 goes into 305665.

Moving on to step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 80

On to step 2:
80 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 80

Moving on to step 3:
80 goes into 305 3 times with a remainder of 65.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 240 away from 305, we end up with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 80

Let's proceed to step 4:
The number 80 fits into 656 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 16 after subtracting 640 from 656.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 80

Going ahead to step 5:
80 can be fit into 166 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 382.0
Subtract 160 from 166 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 80

Step 6:
80 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 3820.0
If we subtract 0 from 65, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
When dividing 650 by 80, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 3820.8
Subtract 640 from 650 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 3820.81
Deduct 80 from 100 and we're left with 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:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3820.812
If we subtract 160 from 200, we 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 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3820.8125
If we subtract 400 from 400, 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 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3820.8125
If we take 0 away from 0, we end up 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.

Moving on to step 12:
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: 3820.8125
If we take 0 away from 0, we end up 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.

The final outcome is 3820.8125, with a leftover of 0.0.
