Let's divide 313901 by 90
Let's see how many times 90 fits into 313901.

Going ahead 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
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 90

Advancing to step 2:
90 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 90

Moving on to step 3:
If we divide 313 by 90, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 270 from 313 and we're left with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 90

Let's proceed to step 4:
90 goes into 439 4 times with a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 360 from 439 leaves us with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 90

Going ahead to step 5:
90 can be fit into 790 8 times, resulting in a remainder of 70.
The next digit of our result is 8. 
Result so far: 348.0
Deduct 720 from 790 and we're left with 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 90

Going ahead to step 6:
90 can be fit into 701 7 times, resulting in a remainder of 71.
The next digit of our result is 7. 
Result so far: 3487.0
Subtract 630 from 701 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
The number 90 fits into 710 7 times, leaving a remainder of 80.
Write down 7 as next digit of the result. 
Result so far: 3487.7
The remainder is 80 after subtracting 630 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 3487.78
Subtract 720 from 800 to 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.

Let's proceed to step 9:
800 divided by 90 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 3487.788
Subtracting 720 from 800 leaves us 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.

Our division results in 3487.788 with a remaining 0.008.
