We look at the division of 404639 by 89 
Let's see how many times 89 fits into 404639.

Step 1:
If we divide 4 by 89, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 89

Step 2:
89 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 89

On to step 3:
89 can be fit into 404 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 356 from 404 leaves us with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 89

Let's proceed to step 4:
If we divide 486 by 89, we get 5 and a remainder of 41.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 445 from 486, we get 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 89

Going ahead to step 5:
89 goes into 413 4 times with a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 454.0
If we take 356 away from 413, we end up with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 89

Going ahead to step 6:
89 can be fit into 579 6 times, resulting in a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 4546.0
If we subtract 534 from 579, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
89 can be fit into 450 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4546.5
If we take 445 away from 450, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 89 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 4546.5
Deduct 0 from 50 and we're left 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.

On to step 9:
The number 89 fits into 500 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4546.505
The remainder is 55 after subtracting 445 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
When dividing 550 by 89, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 4546.5056
Subtracting 534 from 550 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
89 goes into 160 1 times with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 4546.50561
Deduct 89 from 160 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.

On to step 12:
When dividing 710 by 89, we get 7 with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 4546.505617
Subtracting 623 from 710 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
89 goes into 870 9 times with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 4546.5056179
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.

Going ahead to step 14:
The number 89 fits into 690 7 times, leaving a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 4546.50561797
The remainder is 67 after subtracting 623 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 4546.50561797, with a leftover of 6.7e-08.
