Let's divide 303188 by 90
We want to divide 303188 by 90.

Let's proceed to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 90

Advancing to step 2:
90 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 90

Moving on to step 3:
303 divided by 90 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 270 from 303 to get 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 90

Advancing to step 4:
331 divided by 90 is 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 270 from 331, we get 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 90

Moving on to step 5:
The number 90 fits into 618 6 times, leaving a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 336.0
The remainder is 78 after subtracting 540 from 618.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 90

Going ahead to step 6:
90 can be fit into 788 8 times, resulting in a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 3368.0
If we subtract 720 from 788, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
680 divided by 90 is 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 3368.7
The remainder is 50 after subtracting 630 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
90 goes into 500 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 3368.75
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3368.755
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 3368.755 with a balance of 0.005.
