63556591 divided by 780 
Our goal is to divide 63556591 by 780.

Let's proceed to step 1:
The number 780 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 780

Step 2:
The number 780 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 780

Let's proceed to step 3:
When dividing 635 by 780, we get 0 with a remainder of 635.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 635 after subtracting 0 from 635.
Append the next digit (5) from the dividend to 635 and continue with: 6355 / 780

Let's proceed to step 4:
6355 divided by 780 is 8 with a remainder of 115.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 115 after subtracting 6240 from 6355.
Take the next digit (6) from the dividend and append it to 115, then repeat: 1156 / 780

Going ahead to step 5:
780 can be fit into 1156 1 times, resulting in a remainder of 376.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 376 after subtracting 780 from 1156.
Take the next digit (5) from the dividend and append it to 376, then repeat: 3765 / 780

On to step 6:
If we divide 3765 by 780, we get 4 and a remainder of 645.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
The remainder is 645 after subtracting 3120 from 3765.
Bring next digit (9) of the dividend behind the 645 and repeat the process: 6459 / 780

Going ahead to step 7:
780 goes into 6459 8 times with a remainder of 219.
Write down 8 as next digit of the result. 
Result so far: 8148.0
Deduct 6240 from 6459 and we're left with 219.
Take the next digit (1) from the dividend and append it to 219, then repeat: 2191 / 780

On to step 8:
780 can be fit into 2191 2 times, resulting in a remainder of 631.
Use 2 as the next digit of our solution. 
Result so far: 81482.0
If we subtract 1560 from 2191, we get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Let's proceed to step 9:
When dividing 6310 by 780, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 81482.8
The remainder is 70 after subtracting 6240 from 6310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
The number 780 fits into 700 0 times, leaving a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 81482.8
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 11:
When dividing 7000 by 780, we get 8 with a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 81482.808
Deduct 6240 from 7000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 12:
780 can be fit into 7600 9 times, resulting in a remainder of 580.
Put 9 as the next digit of the answer. 
Result so far: 81482.8089
Subtracting 7020 from 7600 leaves us 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.

Going ahead to step 13:
If we divide 5800 by 780, we get 7 and a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 81482.80897
The remainder is 340 after subtracting 5460 from 5800.
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 14:
If we divide 3400 by 780, we get 4 and a remainder of 280.
The next digit of our result is 4. 
Result so far: 81482.808974
Deduct 3120 from 3400 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
780 can be fit into 2800 3 times, resulting in a remainder of 460.
The next digit of our result is 3. 
Result so far: 81482.8089743
Deduct 2340 from 2800 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 16:
780 can be fit into 4600 5 times, resulting in a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 81482.80897435
The remainder is 700 after subtracting 3900 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 81482.80897435, with a leftover of 7e-07.
