We're dividing 386718 by 90 
Let's see how many times 90 fits into 386718.

Advancing to step 1:
90 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 90

Step 2:
If we divide 38 by 90, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 90

Let's proceed to step 3:
The number 90 fits into 386 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 360 from 386 to get 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 90

Going ahead to step 4:
90 goes into 267 2 times with a remainder of 87.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 180 from 267, we get 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 90

Advancing to step 5:
The number 90 fits into 871 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
If we take 810 away from 871, we end up with 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 90

Moving on to step 6:
618 divided by 90 is 6 with a remainder of 78.
The next digit of our result is 6. 
Result so far: 4296.0
Deduct 540 from 618 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
90 can be fit into 780 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 4296.8
Subtract 720 from 780 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 4296.86
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 90, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4296.866
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 4296.866 with a balance of 0.006.
