Let's divide 39995737 by 780
We're looking to find how many times 780 goes into 39995737.

Step 1:
780 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 780

On to step 2:
If we divide 39 by 780, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 780

Advancing to step 3:
780 goes into 399 0 times with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 399 after subtracting 0 from 399.
Grab the next digit (9) from the dividend, add it to 399, then carry on: 3999 / 780

On to step 4:
780 goes into 3999 5 times with a remainder of 99.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 3900 from 3999 and we're left with 99.
Grab the next digit (5) from the dividend, add it to 99, then carry on: 995 / 780

Advancing to step 5:
The number 780 fits into 995 1 times, leaving a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 780 from 995, we get 215.
Include the next digit (7) from the dividend after 215, then repeat: 2157 / 780

Going ahead to step 6:
When dividing 2157 by 780, we get 2 with a remainder of 597.
The next digit of our result is 2. 
Result so far: 512.0
Subtracting 1560 from 2157 leaves us with 597.
Take the next digit (3) from the dividend and append it to 597, then repeat: 5973 / 780

Let's proceed to step 7:
780 goes into 5973 7 times with a remainder of 513.
The number 7 becomes the next digit in our result. 
Result so far: 5127.0
If we take 5460 away from 5973, we end up with 513.
Fetch the next digit (7) from the dividend, attach it to 513 and continue: 5137 / 780

On to step 8:
When dividing 5137 by 780, we get 6 with a remainder of 457.
Use 6 as the next digit of our solution. 
Result so far: 51276.0
Subtract 4680 from 5137 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

On to step 9:
The number 780 fits into 4570 5 times, leaving a remainder of 670.
Use 5 as the next digit of our solution. 
Result so far: 51276.5
If we take 3900 away from 4570, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 10:
780 can be fit into 6700 8 times, resulting in a remainder of 460.
The next digit of our result is 8. 
Result so far: 51276.58
The remainder is 460 after subtracting 6240 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
The number 780 fits into 4600 5 times, leaving a remainder of 700.
The next digit of our result is 5. 
Result so far: 51276.585
If we take 3900 away from 4600, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 12:
7000 divided by 780 is 8 with a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 51276.5858
The remainder is 760 after subtracting 6240 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 13:
7600 divided by 780 is 9 with a remainder of 580.
The next digit of our result is 9. 
Result so far: 51276.58589
If we take 7020 away from 7600, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 14:
5800 divided by 780 is 7 with a remainder of 340.
Record the quotient 7 as the next digit in the result. 
Result so far: 51276.585897
If we subtract 5460 from 5800, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 15:
The number 780 fits into 3400 4 times, leaving a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 51276.5858974
If we subtract 3120 from 3400, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
The number 780 fits into 2800 3 times, leaving a remainder of 460.
Use 3 as the next digit of our solution. 
Result so far: 51276.58589743
Subtract 2340 from 2800 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

In conclusion, the division gives 51276.58589743 with a balance of 4.6e-07.
