365555 divided by 80 
We're looking to find how many times 80 goes into 365555.

Advancing to step 1:
3 divided by 80 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 80

Advancing to step 2:
If we divide 36 by 80, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 80

Moving on to step 3:
If we divide 365 by 80, we get 4 and a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 320 from 365 to get 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 80

Advancing to step 4:
When dividing 455 by 80, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 55 after subtracting 400 from 455.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 80

Advancing to step 5:
If we divide 555 by 80, we get 6 and a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 456.0
Subtract 480 from 555 to get 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 80

Step 6:
When dividing 755 by 80, we get 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 4569.0
Subtract 720 from 755 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
80 can be fit into 350 4 times, resulting in a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4569.4
Subtracting 320 from 350 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 4569.43
If we take 240 away from 300, we end up 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.

Moving on to step 9:
600 divided by 80 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 4569.437
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.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4569.4375
If we take 400 away from 400, 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 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4569.4375
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.

On to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4569.4375
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 4569.4375, with a leftover of 0.0.
