313703 ÷ 90 
We want to divide 313703 by 90.

Going ahead to step 1:
90 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 90

Going ahead to step 2:
31 divided by 90 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 90

Going ahead to step 3:
When dividing 313 by 90, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 270 away from 313, we end up with 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 90

Let's proceed to step 4:
The number 90 fits into 437 4 times, leaving a remainder of 77.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 77 after subtracting 360 from 437.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 90

Going ahead to step 5:
90 can be fit into 770 8 times, resulting in a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 348.0
Deduct 720 from 770 and we're left with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 90

Going ahead to step 6:
90 goes into 503 5 times with a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 3485.0
If we subtract 450 from 503, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
When dividing 530 by 90, we get 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 3485.5
Deduct 450 from 530 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
90 goes into 800 8 times with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 3485.58
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
The next digit of our result is 8. 
Result so far: 3485.588
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 3485.588 with a balance of 0.008.
