Let's divide 86578383 by 780
We're looking to find how many times 780 goes into 86578383.

Let's proceed to step 1:
If we divide 8 by 780, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 780

On to step 2:
780 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 780

Going ahead to step 3:
If we divide 865 by 780, we get 1 and a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 780 from 865 leaves us with 85.
Fetch the next digit (7) from the dividend, attach it to 85 and continue: 857 / 780

Step 4:
780 can be fit into 857 1 times, resulting in a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 780 away from 857, we end up with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 780

On to step 5:
When dividing 778 by 780, we get 0 with a remainder of 778.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Deduct 0 from 778 and we're left with 778.
Append the next digit (3) from the dividend to 778 and continue with: 7783 / 780

On to step 6:
780 goes into 7783 9 times with a remainder of 763.
The number 9 becomes the next digit in our result. 
Result so far: 1109.0
Subtracting 7020 from 7783 leaves us with 763.
Take the next digit (8) from the dividend and append it to 763, then repeat: 7638 / 780

Advancing to step 7:
7638 divided by 780 is 9 with a remainder of 618.
Use 9 as the next digit of our solution. 
Result so far: 11099.0
Subtracting 7020 from 7638 leaves us with 618.
Include the next digit (3) from the dividend after 618, then repeat: 6183 / 780

On to step 8:
6183 divided by 780 is 7 with a remainder of 723.
The number 7 becomes the next digit in our result. 
Result so far: 110997.0
Subtract 5460 from 6183 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Advancing to step 9:
When dividing 7230 by 780, we get 9 with a remainder of 210.
The next digit of our result is 9. 
Result so far: 110997.9
Subtract 7020 from 7230 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
2100 divided by 780 is 2 with a remainder of 540.
The next digit of our result is 2. 
Result so far: 110997.92
Subtract 1560 from 2100 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 11:
780 goes into 5400 6 times with a remainder of 720.
Use 6 as the next digit of our solution. 
Result so far: 110997.926
If we subtract 4680 from 5400, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
780 goes into 7200 9 times with a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 110997.9269
The remainder is 180 after subtracting 7020 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
When dividing 1800 by 780, we get 2 with a remainder of 240.
The next digit of our result is 2. 
Result so far: 110997.92692
If we take 1560 away from 1800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
When dividing 2400 by 780, we get 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 110997.926923
If we subtract 2340 from 2400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
The number 780 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 110997.926923
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 16:
6000 divided by 780 is 7 with a remainder of 540.
The next digit of our result is 7. 
Result so far: 110997.92692307
Subtract 5460 from 6000 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final result is 110997.92692307 with a remainder of 5.4e-07.
