We look at the division of 604390 by 68 
Our goal is to divide 604390 by 68.

Step 1:
If we divide 6 by 68, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 68

Advancing to step 2:
60 divided by 68 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 68

Step 3:
68 can be fit into 604 8 times, resulting in a remainder of 60.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 544 from 604 and we're left with 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 68

Going ahead to step 4:
68 can be fit into 603 8 times, resulting in a remainder of 59.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
The remainder is 59 after subtracting 544 from 603.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 68

Let's proceed to step 5:
When dividing 599 by 68, we get 8 with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 888.0
If we subtract 544 from 599, we get 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 68

Moving on to step 6:
When dividing 550 by 68, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8888.0
The remainder is 6 after subtracting 544 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 68, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8888.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
If we divide 600 by 68, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8888.08
The remainder is 56 after subtracting 544 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
68 can be fit into 560 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 8888.088
Subtract 544 from 560 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 8888.088 with a remainder of 0.0016.
