438663 ÷ 89 
Let's see how many times 89 fits into 438663.

Moving on to step 1:
When dividing 4 by 89, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 89

Moving on to step 2:
43 divided by 89 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 89

Advancing to step 3:
89 can be fit into 438 4 times, resulting in a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 82 after subtracting 356 from 438.
Fetch the next digit (6) from the dividend, attach it to 82 and continue: 826 / 89

Let's proceed to step 4:
If we divide 826 by 89, we get 9 and a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 801 from 826, we get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 89

Advancing to step 5:
If we divide 256 by 89, we get 2 and a remainder of 78.
The next digit of our result is 2. 
Result so far: 492.0
If we subtract 178 from 256, we get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 89

Moving on to step 6:
The number 89 fits into 783 8 times, leaving a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 4928.0
Deduct 712 from 783 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
89 goes into 710 7 times with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 4928.7
Subtract 623 from 710 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 8:
89 goes into 870 9 times with a remainder of 69.
The next digit of our result is 9. 
Result so far: 4928.79
The remainder is 69 after subtracting 801 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
If we divide 690 by 89, we get 7 and a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 4928.797
Subtract 623 from 690 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
89 can be fit into 670 7 times, resulting in a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 4928.7977
If we subtract 623 from 670, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 4928.7977 and a remainder of 0.00047.
