We divide 334303 by 90
We want to divide 334303 by 90.

On to step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 90

Going ahead to step 2:
33 divided by 90 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 90

Step 3:
334 divided by 90 is 3 with a remainder of 64.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 64 after subtracting 270 from 334.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 90

Step 4:
The number 90 fits into 643 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we take 630 away from 643, we end up with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 90

Step 5:
If we divide 130 by 90, we get 1 and a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 371.0
If we subtract 90 from 130, we get 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 90

Advancing to step 6:
The number 90 fits into 403 4 times, leaving a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 3714.0
Subtracting 360 from 403 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
430 divided by 90 is 4 with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 3714.4
Subtract 360 from 430 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 3714.47
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 3714.477
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 3714.477, with a leftover of 0.007.
