Let's divide 65409830 by 664
Let's see how many times 664 fits into 65409830.

Moving on to step 1:
If we divide 6 by 664, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 664

Moving on to step 2:
65 divided by 664 is 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 664

Advancing to step 3:
When dividing 654 by 664, we get 0 with a remainder of 654.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 654, we end up with 654.
Take the next digit (0) from the dividend and append it to 654, then repeat: 6540 / 664

On to step 4:
664 can be fit into 6540 9 times, resulting in a remainder of 564.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 5976 from 6540 leaves us with 564.
Append the next digit (9) from the dividend to 564 and continue with: 5649 / 664

Going ahead to step 5:
The number 664 fits into 5649 8 times, leaving a remainder of 337.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtracting 5312 from 5649 leaves us with 337.
Include the next digit (8) from the dividend after 337, then repeat: 3378 / 664

Let's proceed to step 6:
The number 664 fits into 3378 5 times, leaving a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 985.0
If we take 3320 away from 3378, we end up with 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 664

Step 7:
When dividing 583 by 664, we get 0 with a remainder of 583.
The next digit of our result is 0. 
Result so far: 9850.0
Subtracting 0 from 583 leaves us with 583.
Include the next digit (0) from the dividend after 583, then repeat: 5830 / 664

Step 8:
When dividing 5830 by 664, we get 8 with a remainder of 518.
The next digit of our result is 8. 
Result so far: 98508.0
If we take 5312 away from 5830, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 9:
5180 divided by 664 is 7 with a remainder of 532.
Record the quotient 7 as the next digit in the result. 
Result so far: 98508.7
If we take 4648 away from 5180, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 10:
If we divide 5320 by 664, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 98508.78
Subtracting 5312 from 5320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
664 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 98508.78
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
The number 664 fits into 800 1 times, leaving a remainder of 136.
Use 1 as the next digit of our solution. 
Result so far: 98508.7801
Deduct 664 from 800 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
1360 divided by 664 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 98508.78012
Subtracting 1328 from 1360 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
The number 664 fits into 320 0 times, leaving a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 98508.78012
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
When dividing 3200 by 664, we get 4 with a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 98508.7801204
The remainder is 544 after subtracting 2656 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 16:
664 can be fit into 5440 8 times, resulting in a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 98508.78012048
Subtracting 5312 from 5440 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 98508.78012048 with a balance of 1.28e-07.
