We divide 603427 by 90
Let's see how many times 90 fits into 603427.

Advancing to step 1:
If we divide 6 by 90, we get 0 and 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.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 90

On to step 2:
90 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 90

Let's proceed to step 3:
90 goes into 603 6 times with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 540 from 603, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 90

Going ahead to step 4:
90 can be fit into 634 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 67.0
The remainder is 4 after subtracting 630 from 634.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 90

On to step 5:
When dividing 42 by 90, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 670.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 90

On to step 6:
90 can be fit into 427 4 times, resulting in a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 6704.0
The remainder is 67 after subtracting 360 from 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
670 divided by 90 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 6704.7
If we subtract 630 from 670, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 6704.74
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 6704.744
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 6704.744 with a remainder of 0.004.
