We're dividing 721142 by 80 
We want to divide 721142 by 80.

Advancing to step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 80

On to step 2:
If we divide 72 by 80, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 80

On to step 3:
80 goes into 721 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 720 from 721 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 80

Step 4:
If we divide 11 by 80, we get 0 and a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 11, we get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 80

Moving on to step 5:
80 can be fit into 114 1 times, resulting in a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 901.0
Subtract 80 from 114 to get 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 80

On to step 6:
80 goes into 342 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 9014.0
If we subtract 320 from 342, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
80 goes into 220 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 9014.2
The remainder is 60 after subtracting 160 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 9014.27
Deduct 560 from 600 and we're left 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 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9014.275
The remainder is 0 after subtracting 400 from 400.
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 number 0 becomes the next digit in our result. 
Result so far: 9014.275
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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9014.275
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.

In conclusion, the division gives 9014.275 with a balance of 0.0.
