535664 divided by 80 
We want to figure out the number of times 535664 can be divided by 80.

Moving on to step 1:
5 divided by 80 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 80

Step 2:
53 divided by 80 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 80

Going ahead to step 3:
The number 80 fits into 535 6 times, leaving a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 480 away from 535, we end up with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 80

On to step 4:
If we divide 556 by 80, we get 6 and a remainder of 76.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 480 from 556, we get 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 80

Step 5:
80 can be fit into 766 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 669.0
Subtracting 720 from 766 leaves us with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 80

Moving on to step 6:
464 divided by 80 is 5 with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 6695.0
If we take 400 away from 464, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
The number 80 fits into 640 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 6695.8
Deduct 640 from 640 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.

Advancing to step 8:
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: 6695.8
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.

Advancing 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: 6695.8
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.

Our division results in 6695.8 with a remaining 0.0.
