721052 ÷ 80 
Let's see how many times 80 fits into 721052.

On to step 1:
7 divided by 80 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 80

Let's proceed to step 2:
If we divide 72 by 80, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 80

Moving on to step 3:
If we divide 721 by 80, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
If we take 720 away from 721, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 80

Going ahead to step 4:
If we divide 10 by 80, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 80

Step 5:
The number 80 fits into 105 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 901.0
If we subtract 80 from 105, we get 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 80

Moving on to step 6:
If we divide 252 by 80, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 9013.0
Subtract 240 from 252 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
The number 80 fits into 120 1 times, leaving a remainder of 40.
The next digit of our result is 1. 
Result so far: 9013.1
If we take 80 away from 120, we end up 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.

Advancing to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9013.15
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.

Moving on to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9013.15
The remainder is 0 after subtracting 0 from 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 10:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9013.15
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.

The quotient of the division is 9013.15, and the remainder is 0.0.
