438774 ÷ 90 
We want to divide 438774 by 90.

On to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
The next digit of our result is 0. 
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

On to step 2:
90 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 90

Let's proceed to step 3:
If we divide 438 by 90, we get 4 and 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.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 90

Going ahead to step 4:
If we divide 787 by 90, we get 8 and a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 720 away from 787, we end up with 67.
Append the next digit (7) from the dividend to 67 and continue with: 677 / 90

On to step 5:
90 goes into 677 7 times with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 487.0
If we subtract 630 from 677, we get 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 90

Going ahead to step 6:
90 goes into 474 5 times with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 4875.0
If we take 450 away from 474, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
When dividing 240 by 90, we get 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 4875.2
The remainder is 60 after subtracting 180 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 90 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 4875.26
If we subtract 540 from 600, we 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.

Going ahead to step 9:
600 divided by 90 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 4875.266
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.

The quotient of the division is 4875.266, and the remainder is 0.006.
