399480 divided by 89 
Let's see how many times 89 fits into 399480.

Let's proceed to step 1:
89 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 89

Moving on to step 2:
The number 89 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 89

Moving on to step 3:
89 can be fit into 399 4 times, resulting in a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 356 away from 399, we end up with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 89

Going ahead to step 4:
89 can be fit into 434 4 times, resulting in a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 78 after subtracting 356 from 434.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 89

On to step 5:
89 goes into 788 8 times with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
Subtract 712 from 788 to get 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 89

Advancing to step 6:
If we divide 760 by 89, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 4488.0
Subtract 712 from 760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 89 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4488.5
If we take 445 away from 480, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
350 divided by 89 is 3 with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 4488.53
Deduct 267 from 350 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
If we divide 830 by 89, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 4488.539
Subtracting 801 from 830 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
If we divide 290 by 89, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 4488.5393
Subtract 267 from 290 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
89 goes into 230 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 4488.53932
The remainder is 52 after subtracting 178 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
When dividing 520 by 89, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4488.539325
The remainder is 75 after subtracting 445 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
The number 89 fits into 750 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 4488.5393258
Subtract 712 from 750 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
89 goes into 380 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4488.53932584
Subtract 356 from 380 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 4488.53932584 with a balance of 2.4e-08.
