365597 ÷ 80 
We want to divide 365597 by 80.

Advancing to step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 80

On to step 2:
36 divided by 80 is 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 80

Let's proceed to step 3:
The number 80 fits into 365 4 times, leaving a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
If we take 320 away from 365, we end up with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 80

Going ahead to step 4:
When dividing 455 by 80, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 400 from 455, we get 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 80

Step 5:
80 goes into 559 6 times with a remainder of 79.
The next digit of our result is 6. 
Result so far: 456.0
The remainder is 79 after subtracting 480 from 559.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 80

Going ahead to step 6:
80 goes into 797 9 times with a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 4569.0
If we take 720 away from 797, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
When dividing 770 by 80, we get 9 with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 4569.9
The remainder is 50 after subtracting 720 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4569.96
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed 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: 4569.962
Subtracting 160 from 200 leaves us 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:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4569.9625
Subtract 400 from 400 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.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4569.9625
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 12:
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: 4569.9625
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.

After the division, we end up with 4569.9625 and a remainder of 0.0.
