We look at the division of 843290 by 72 
Let's see how many times 72 fits into 843290.

Going ahead to step 1:
72 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 72

Advancing to step 2:
When dividing 84 by 72, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 12 after subtracting 72 from 84.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 72

Let's proceed to step 3:
72 goes into 123 1 times with a remainder of 51.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 72 from 123 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 72

Advancing to step 4:
If we divide 512 by 72, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 504 away from 512, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 72

On to step 5:
When dividing 89 by 72, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1171.0
Subtract 72 from 89 to get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 72

On to step 6:
The number 72 fits into 170 2 times, leaving a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 11712.0
Subtract 144 from 170 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
The number 72 fits into 260 3 times, leaving a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 11712.3
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
When dividing 440 by 72, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 11712.36
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 72, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11712.361
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 11712.3611
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 11712.3611 with a remainder of 8e-05.
