We're dividing 723564 by 80 
Let's see how many times 80 fits into 723564.

Advancing to step 1:
If we divide 7 by 80, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 80

On to step 2:
80 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 80

Let's proceed to step 3:
723 divided by 80 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 720 away from 723, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 80

Advancing to step 4:
When dividing 35 by 80, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 80

Going ahead to step 5:
80 can be fit into 356 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 904.0
Subtract 320 from 356 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 80

On to step 6:
The number 80 fits into 364 4 times, leaving a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 9044.0
If we take 320 away from 364, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
When dividing 440 by 80, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 9044.5
Subtract 400 from 440 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.

Advancing to step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 9044.55
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.

After the division, we end up with 9044.55 and a remainder of 0.0.
