520365 divided by 80 
Let's see how many times 80 fits into 520365.

Let's proceed to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 80

Moving on to step 2:
80 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 80

Step 3:
80 can be fit into 520 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 480 from 520 and we're left with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 80

On to step 4:
80 can be fit into 403 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 65.0
Deduct 400 from 403 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 80

Advancing to step 5:
80 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 650.0
The remainder is 36 after subtracting 0 from 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 80

Advancing to step 6:
The number 80 fits into 365 4 times, leaving a remainder of 45.
The next digit of our result is 4. 
Result so far: 6504.0
If we subtract 320 from 365, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
450 divided by 80 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6504.5
If we take 400 away from 450, we end up with 50.
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.
Use 6 as the next digit of our solution. 
Result so far: 6504.56
If we take 480 away from 500, we end up 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.

Going ahead to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 6504.562
Subtract 160 from 200 to 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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6504.5625
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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6504.5625
Subtracting 0 from 0 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.

Step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6504.5625
Subtracting 0 from 0 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.

After the division, we end up with 6504.5625 and a remainder of 0.0.
