We divide 358310 by 90
We want to divide 358310 by 90.

Moving 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
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 90

On to step 2:
90 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 90

Let's proceed to step 3:
The number 90 fits into 358 3 times, leaving a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 270 away from 358, we end up with 88.
Append the next digit (3) from the dividend to 88 and continue with: 883 / 90

Step 4:
883 divided by 90 is 9 with a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 810 from 883 and we're left with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 90

Step 5:
The number 90 fits into 731 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 398.0
The remainder is 11 after subtracting 720 from 731.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 90

Let's proceed to step 6:
When dividing 110 by 90, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 3981.0
The remainder is 20 after subtracting 90 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
When dividing 200 by 90, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 3981.2
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 3981.22
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 3981.22 and a remainder of 0.02.
