We're dividing 843204 by 72 
Let's see how many times 72 fits into 843204.

Going ahead to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 72

Advancing to step 2:
72 goes into 84 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 84 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 72

Moving on to step 3:
When dividing 123 by 72, we get 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 72 from 123, we get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 72

Moving on to step 4:
72 goes into 512 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 8 after subtracting 504 from 512.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 72

Moving on to step 5:
72 goes into 80 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1171.0
Subtracting 72 from 80 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 72

On to step 6:
72 can be fit into 84 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 11711.0
Subtracting 72 from 84 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
72 goes into 120 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 11711.1
Subtract 72 from 120 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 11711.16
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 11711.166
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 11711.166, and the remainder is 0.0048.
