39664656 ÷ 784 
We want to divide 39664656 by 784.

Let's proceed to step 1:
784 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 784

Going ahead to step 2:
The number 784 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 784

Moving on to step 3:
396 divided by 784 is 0 with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 396 leaves us with 396.
Grab the next digit (6) from the dividend, add it to 396, then carry on: 3966 / 784

On to step 4:
3966 divided by 784 is 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 3920 from 3966 leaves us with 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 784

Advancing to step 5:
The number 784 fits into 464 0 times, leaving a remainder of 464.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 464 to get 464.
Fetch the next digit (6) from the dividend, attach it to 464 and continue: 4646 / 784

Moving on to step 6:
The number 784 fits into 4646 5 times, leaving a remainder of 726.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
If we subtract 3920 from 4646, we get 726.
Include the next digit (5) from the dividend after 726, then repeat: 7265 / 784

Let's proceed to step 7:
7265 divided by 784 is 9 with a remainder of 209.
The number 9 becomes the next digit in our result. 
Result so far: 5059.0
Subtracting 7056 from 7265 leaves us with 209.
Take the next digit (6) from the dividend and append it to 209, then repeat: 2096 / 784

Advancing to step 8:
784 goes into 2096 2 times with a remainder of 528.
Write down 2 as next digit of the result. 
Result so far: 50592.0
Subtracting 1568 from 2096 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 9:
When dividing 5280 by 784, we get 6 with a remainder of 576.
The next digit of our result is 6. 
Result so far: 50592.6
Deduct 4704 from 5280 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 10:
784 can be fit into 5760 7 times, resulting in a remainder of 272.
The number 7 becomes the next digit in our result. 
Result so far: 50592.67
Subtracting 5488 from 5760 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 11:
784 goes into 2720 3 times with a remainder of 368.
The next digit of our result is 3. 
Result so far: 50592.673
If we subtract 2352 from 2720, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
The number 784 fits into 3680 4 times, leaving a remainder of 544.
Write down 4 as next digit of the result. 
Result so far: 50592.6734
Subtract 3136 from 3680 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 13:
The number 784 fits into 5440 6 times, leaving a remainder of 736.
Put 6 as the next digit of the answer. 
Result so far: 50592.67346
Subtracting 4704 from 5440 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 14:
If we divide 7360 by 784, we get 9 and a remainder of 304.
Use 9 as the next digit of our solution. 
Result so far: 50592.673469
If we take 7056 away from 7360, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
3040 divided by 784 is 3 with a remainder of 688.
The number 3 becomes the next digit in our result. 
Result so far: 50592.6734693
Subtracting 2352 from 3040 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 16:
When dividing 6880 by 784, we get 8 with a remainder of 608.
Record the quotient 8 as the next digit in the result. 
Result so far: 50592.67346938
If we subtract 6272 from 6880, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

In conclusion, the division gives 50592.67346938 with a balance of 6.08e-07.
