40430902 divided by 489 
We're looking to find how many times 489 goes into 40430902.

Step 1:
When dividing 4 by 489, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 489

Moving on to step 2:
The number 489 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 489

Advancing to step 3:
When dividing 404 by 489, we get 0 with a remainder of 404.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 404, we get 404.
Bring next digit (3) of the dividend behind the 404 and repeat the process: 4043 / 489

Moving on to step 4:
489 goes into 4043 8 times with a remainder of 131.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 131 after subtracting 3912 from 4043.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 489

Going ahead to step 5:
489 goes into 1310 2 times with a remainder of 332.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we take 978 away from 1310, we end up with 332.
Take the next digit (9) from the dividend and append it to 332, then repeat: 3329 / 489

Step 6:
489 can be fit into 3329 6 times, resulting in a remainder of 395.
Write down 6 as next digit of the result. 
Result so far: 826.0
Deduct 2934 from 3329 and we're left with 395.
Fetch the next digit (0) from the dividend, attach it to 395 and continue: 3950 / 489

Moving on to step 7:
489 can be fit into 3950 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 8268.0
Subtracting 3912 from 3950 leaves us with 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 489

Let's proceed to step 8:
If we divide 382 by 489, we get 0 and a remainder of 382.
The next digit of our result is 0. 
Result so far: 82680.0
The remainder is 382 after subtracting 0 from 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 9:
When dividing 3820 by 489, we get 7 with a remainder of 397.
The number 7 becomes the next digit in our result. 
Result so far: 82680.7
Subtracting 3423 from 3820 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 10:
If we divide 3970 by 489, we get 8 and a remainder of 58.
The next digit of our result is 8. 
Result so far: 82680.78
If we subtract 3912 from 3970, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
If we divide 580 by 489, we get 1 and a remainder of 91.
The next digit of our result is 1. 
Result so far: 82680.781
If we subtract 489 from 580, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 12:
489 goes into 910 1 times with a remainder of 421.
Write down 1 as next digit of the result. 
Result so far: 82680.7811
Subtracting 489 from 910 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

In conclusion, the division gives 82680.7811 with a balance of 0.00421.
