336564 ÷ 80 
We're looking to find how many times 80 goes into 336564.

Let's proceed to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 80

Going ahead to step 2:
When dividing 33 by 80, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 80

On to step 3:
336 divided by 80 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 320 from 336, we get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 80

Moving on to step 4:
The number 80 fits into 165 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 160 from 165, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 80

Let's proceed to step 5:
The number 80 fits into 56 0 times, leaving a remainder of 56.
The next digit of our result is 0. 
Result so far: 420.0
If we take 0 away from 56, we end up with 56.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 80

Step 6:
80 can be fit into 564 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 4207.0
If we take 560 away from 564, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
40 divided by 80 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4207.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4207.05
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.

On to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4207.05
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.

Moving on to step 10:
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: 4207.05
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 result is 4207.05 with a remainder of 0.0.
