We divide 90840 by 72
We want to figure out the number of times 90840 can be divided by 72.

Going ahead to step 1:
If we divide 9 by 72, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 72

Advancing to step 2:
72 can be fit into 90 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 90, we get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 72

Step 3:
188 divided by 72 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 144 away from 188, we end up with 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 72

Let's proceed to step 4:
When dividing 444 by 72, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we subtract 432 from 444, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 72

Going ahead to step 5:
120 divided by 72 is 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 1261.0
If we subtract 72 from 120, we 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.

Moving on to step 6:
If we divide 480 by 72, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1261.6
Subtracting 432 from 480 leaves us 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.

Moving on to step 7:
If we divide 480 by 72, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 1261.66
Subtracting 432 from 480 leaves us 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.

In conclusion, the division gives 1261.66 with a balance of 0.048.
