We look at the division of 890404 by 72 
Let's see how many times 72 fits into 890404.

On to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 72

Moving on to step 2:
The number 72 fits into 89 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 72 from 89 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 72

Step 3:
The number 72 fits into 170 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 144 away from 170, we end up with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 72

Going ahead to step 4:
72 goes into 264 3 times with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtract 216 from 264 to get 48.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 72

On to step 5:
When dividing 480 by 72, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 1236.0
Deduct 432 from 480 and we're left with 48.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 72

Let's proceed to step 6:
72 goes into 484 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 12366.0
The remainder is 52 after subtracting 432 from 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
The number 72 fits into 520 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 12366.7
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
If we divide 160 by 72, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 12366.72
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12366.722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 12366.722 and a remainder of 0.0016.
