71650047 ÷ 780 
We're looking to find how many times 780 goes into 71650047.

Going ahead to step 1:
780 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 780

Let's proceed to step 2:
780 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 780

Step 3:
780 can be fit into 716 0 times, resulting in a remainder of 716.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 716 to get 716.
Bring next digit (5) of the dividend behind the 716 and repeat the process: 7165 / 780

Going ahead to step 4:
The number 780 fits into 7165 9 times, leaving a remainder of 145.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7020 from 7165 leaves us with 145.
Include the next digit (0) from the dividend after 145, then repeat: 1450 / 780

On to step 5:
When dividing 1450 by 780, we get 1 with a remainder of 670.
Write down 1 as next digit of the result. 
Result so far: 91.0
Deduct 780 from 1450 and we're left with 670.
Append the next digit (0) from the dividend to 670 and continue with: 6700 / 780

Advancing to step 6:
When dividing 6700 by 780, we get 8 with a remainder of 460.
Put 8 as the next digit of the answer. 
Result so far: 918.0
The remainder is 460 after subtracting 6240 from 6700.
Append the next digit (4) from the dividend to 460 and continue with: 4604 / 780

Advancing to step 7:
780 goes into 4604 5 times with a remainder of 704.
Put 5 as the next digit of the answer. 
Result so far: 9185.0
If we take 3900 away from 4604, we end up with 704.
Append the next digit (7) from the dividend to 704 and continue with: 7047 / 780

On to step 8:
780 goes into 7047 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 91859.0
If we take 7020 away from 7047, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
270 divided by 780 is 0 with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 91859.0
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
When dividing 2700 by 780, we get 3 with a remainder of 360.
The number 3 becomes the next digit in our result. 
Result so far: 91859.03
Subtract 2340 from 2700 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
The number 780 fits into 3600 4 times, leaving a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 91859.034
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
4800 divided by 780 is 6 with a remainder of 120.
The next digit of our result is 6. 
Result so far: 91859.0346
Deduct 4680 from 4800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
1200 divided by 780 is 1 with a remainder of 420.
The next digit of our result is 1. 
Result so far: 91859.03461
If we subtract 780 from 1200, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
The number 780 fits into 4200 5 times, leaving a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 91859.034615
Subtracting 3900 from 4200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
The number 780 fits into 3000 3 times, leaving a remainder of 660.
Use 3 as the next digit of our solution. 
Result so far: 91859.0346153
The remainder is 660 after subtracting 2340 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 16:
6600 divided by 780 is 8 with a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 91859.03461538
Deduct 6240 from 6600 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 91859.03461538 with a remainder of 3.6e-07.
