We look at the division of 600805 by 90 
We're looking to find how many times 90 goes into 600805.

Moving on to step 1:
The number 90 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 90

Step 2:
90 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 90

Advancing to step 3:
600 divided by 90 is 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 540 from 600 and we're left with 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 90

Step 4:
90 goes into 608 6 times with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 540 from 608 leaves us with 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 90

Going ahead to step 5:
When dividing 680 by 90, we get 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 667.0
Subtract 630 from 680 to get 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 90

On to step 6:
The number 90 fits into 505 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 6675.0
The remainder is 55 after subtracting 450 from 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
90 can be fit into 550 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 6675.6
If we take 540 away from 550, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 6675.61
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 6675.611
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 6675.611 with a balance of 0.001.
