We're dividing 65486648 by 780 
Our goal is to divide 65486648 by 780.

Let's proceed to step 1:
The number 780 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 780

Going ahead to step 2:
When dividing 65 by 780, we get 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 780

Step 3:
780 goes into 654 0 times with a remainder of 654.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 654, we get 654.
Take the next digit (8) from the dividend and append it to 654, then repeat: 6548 / 780

Moving on to step 4:
The number 780 fits into 6548 8 times, leaving a remainder of 308.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6240 from 6548, we get 308.
Append the next digit (6) from the dividend to 308 and continue with: 3086 / 780

On to step 5:
When dividing 3086 by 780, we get 3 with a remainder of 746.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtract 2340 from 3086 to get 746.
Append the next digit (6) from the dividend to 746 and continue with: 7466 / 780

Moving on to step 6:
If we divide 7466 by 780, we get 9 and a remainder of 446.
Write down 9 as next digit of the result. 
Result so far: 839.0
If we take 7020 away from 7466, we end up with 446.
Include the next digit (4) from the dividend after 446, then repeat: 4464 / 780

Let's proceed to step 7:
780 can be fit into 4464 5 times, resulting in a remainder of 564.
The next digit of our result is 5. 
Result so far: 8395.0
The remainder is 564 after subtracting 3900 from 4464.
Append the next digit (8) from the dividend to 564 and continue with: 5648 / 780

Step 8:
If we divide 5648 by 780, we get 7 and a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 83957.0
Subtracting 5460 from 5648 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 9:
When dividing 1880 by 780, we get 2 with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 83957.2
If we subtract 1560 from 1880, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
When dividing 3200 by 780, we get 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 83957.24
If we subtract 3120 from 3200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
If we divide 800 by 780, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 83957.241
Deduct 780 from 800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 780, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 83957.241
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
780 goes into 2000 2 times with a remainder of 440.
The number 2 becomes the next digit in our result. 
Result so far: 83957.24102
If we subtract 1560 from 2000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 14:
When dividing 4400 by 780, we get 5 with a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 83957.241025
If we subtract 3900 from 4400, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 15:
When dividing 5000 by 780, we get 6 with a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 83957.2410256
If we take 4680 away from 5000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 16:
The number 780 fits into 3200 4 times, leaving a remainder of 80.
The next digit of our result is 4. 
Result so far: 83957.24102564
The remainder is 80 after subtracting 3120 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 83957.24102564, with a leftover of 8e-08.
