We look at the division of 604590 by 72 
We want to figure out the number of times 604590 can be divided by 72.

Advancing to step 1:
6 divided by 72 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 72

Step 2:
72 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 72

On to step 3:
604 divided by 72 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 8.0
If we take 576 away from 604, we end up with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 72

Advancing to step 4:
If we divide 285 by 72, we get 3 and a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 216 from 285 and we're left with 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 72

On to step 5:
When dividing 699 by 72, we get 9 with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 839.0
Subtracting 648 from 699 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 72

Advancing to step 6:
If we divide 510 by 72, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 8397.0
Subtract 504 from 510 to get 6.
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:
When dividing 60 by 72, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 8397.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
If we divide 600 by 72, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8397.08
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
72 can be fit into 240 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 8397.083
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 72, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 8397.0833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 8397.0833 with a remainder of 0.00024.
