We look at the division of 308507 by 90 
Let's see how many times 90 fits into 308507.

Going ahead to step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 90

Let's proceed to step 2:
30 divided by 90 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 90

Step 3:
If we divide 308 by 90, we get 3 and a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 270 from 308, we get 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 90

Moving on to step 4:
385 divided by 90 is 4 with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 360 away from 385, we end up with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 90

Going ahead to step 5:
250 divided by 90 is 2 with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 342.0
Deduct 180 from 250 and we're left with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 90

Step 6:
The number 90 fits into 707 7 times, leaving a remainder of 77.
The next digit of our result is 7. 
Result so far: 3427.0
The remainder is 77 after subtracting 630 from 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
When dividing 770 by 90, we get 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 3427.8
If we subtract 720 from 770, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3427.85
If we take 450 away from 500, we end up 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.

Moving on to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3427.855
The remainder is 50 after subtracting 450 from 500.
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 3427.855 with a balance of 0.005.
