605304 ÷ 90 
We're looking to find how many times 90 goes into 605304.

Going ahead to step 1:
6 divided by 90 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 90

Let's proceed to step 2:
60 divided by 90 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 90

Step 3:
If we divide 605 by 90, we get 6 and a remainder of 65.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 540 from 605 leaves us with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 90

Let's proceed to step 4:
The number 90 fits into 653 7 times, leaving a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we take 630 away from 653, we end up with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 90

Let's proceed to step 5:
If we divide 230 by 90, we get 2 and a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 672.0
If we subtract 180 from 230, we get 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 90

Let's proceed to step 6:
504 divided by 90 is 5 with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 6725.0
Subtracting 450 from 504 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
The number 90 fits into 540 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 6725.6
Deduct 540 from 540 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 90 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6725.6
Subtracting 0 from 0 leaves us with 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 9:
If we divide 0 by 90, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6725.6
Deduct 0 from 0 and we're left with 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 final result is 6725.6 with a remainder of 0.0.
