We look at the division of 978408 by 72 
We want to divide 978408 by 72.

Going ahead to step 1:
If we divide 9 by 72, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 72

Advancing to step 2:
97 divided by 72 is 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 72 from 97 and we're left with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 72

Going ahead to step 3:
When dividing 258 by 72, we get 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 42 after subtracting 216 from 258.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 72

Step 4:
When dividing 424 by 72, we get 5 with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 360 from 424 to get 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 72

Moving on to step 5:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 1358.0
Subtract 576 from 640 to get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 72

Moving on to step 6:
648 divided by 72 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 13589.0
The remainder is 0 after subtracting 648 from 648.
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 7:
The number 72 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13589.0
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.

Moving on to step 8:
If we divide 0 by 72, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13589.0
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.

The quotient of the division is 13589.0, and the remainder is 0.0.
