39984613 ÷ 784 
Let's see how many times 784 fits into 39984613.

On to step 1:
The number 784 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 784

Let's proceed to step 2:
The number 784 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 784

Step 3:
The number 784 fits into 399 0 times, leaving a remainder of 399.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Grab the next digit (8) from the dividend, add it to 399, then carry on: 3998 / 784

Step 4:
784 can be fit into 3998 5 times, resulting in a remainder of 78.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 3920 away from 3998, we end up with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 784

Advancing to step 5:
784 goes into 784 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 784 away from 784, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 784

Let's proceed to step 6:
784 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 510.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 784

Let's proceed to step 7:
784 goes into 61 0 times with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 5100.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 784

Going ahead to step 8:
784 can be fit into 613 0 times, resulting in a remainder of 613.
Use 0 as the next digit of our solution. 
Result so far: 51000.0
If we take 0 away from 613, we end up with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Let's proceed to step 9:
784 goes into 6130 7 times with a remainder of 642.
Put 7 as the next digit of the answer. 
Result so far: 51000.7
If we subtract 5488 from 6130, we get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Advancing to step 10:
If we divide 6420 by 784, we get 8 and a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 51000.78
If we subtract 6272 from 6420, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
784 goes into 1480 1 times with a remainder of 696.
The next digit of our result is 1. 
Result so far: 51000.781
Deduct 784 from 1480 and we're left with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 12:
When dividing 6960 by 784, we get 8 with a remainder of 688.
The number 8 becomes the next digit in our result. 
Result so far: 51000.7818
Subtracting 6272 from 6960 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.

Step 13:
If we divide 6880 by 784, we get 8 and a remainder of 608.
Put 8 as the next digit of the answer. 
Result so far: 51000.78188
Subtracting 6272 from 6880 leaves us with 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 51000.78188 with a balance of 0.000608.
