We're dividing 438767 by 90 
We want to figure out the number of times 438767 can be divided by 90.

Moving on to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 90

Let's proceed to step 2:
90 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 90

Moving on to step 3:
When dividing 438 by 90, we get 4 with a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 360 from 438 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 90

Step 4:
90 goes into 787 8 times with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 720 from 787 to get 67.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 90

On to step 5:
When dividing 676 by 90, we get 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Subtract 630 from 676 to get 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 90

Let's proceed to step 6:
467 divided by 90 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 4875.0
The remainder is 17 after subtracting 450 from 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 90, we get 1 and a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 4875.1
Subtracting 90 from 170 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.

Let's proceed to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
The next digit of our result is 8. 
Result so far: 4875.18
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.

Let's proceed to step 9:
800 divided by 90 is 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 4875.188
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.

The final result is 4875.188 with a remainder of 0.008.
