We're dividing 16863753 by 779 
We're looking to find how many times 779 goes into 16863753.

Advancing to step 1:
The number 779 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 779

Moving on to step 2:
779 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 779

Let's proceed to step 3:
779 goes into 168 0 times with a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 168, we get 168.
Fetch the next digit (6) from the dividend, attach it to 168 and continue: 1686 / 779

Advancing to step 4:
1686 divided by 779 is 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1558 from 1686 and we're left with 128.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 779

On to step 5:
779 goes into 1283 1 times with a remainder of 504.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 779 from 1283, we get 504.
Take the next digit (7) from the dividend and append it to 504, then repeat: 5047 / 779

Let's proceed to step 6:
If we divide 5047 by 779, we get 6 and a remainder of 373.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
If we take 4674 away from 5047, we end up with 373.
Bring next digit (5) of the dividend behind the 373 and repeat the process: 3735 / 779

Going ahead to step 7:
If we divide 3735 by 779, we get 4 and a remainder of 619.
The number 4 becomes the next digit in our result. 
Result so far: 2164.0
The remainder is 619 after subtracting 3116 from 3735.
Include the next digit (3) from the dividend after 619, then repeat: 6193 / 779

Step 8:
6193 divided by 779 is 7 with a remainder of 740.
The number 7 becomes the next digit in our result. 
Result so far: 21647.0
If we subtract 5453 from 6193, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 9:
The number 779 fits into 7400 9 times, leaving a remainder of 389.
Use 9 as the next digit of our solution. 
Result so far: 21647.9
If we take 7011 away from 7400, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 10:
779 goes into 3890 4 times with a remainder of 774.
Record the quotient 4 as the next digit in the result. 
Result so far: 21647.94
If we subtract 3116 from 3890, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Let's proceed to step 11:
The number 779 fits into 7740 9 times, leaving a remainder of 729.
The next digit of our result is 9. 
Result so far: 21647.949
Subtract 7011 from 7740 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Going ahead to step 12:
7290 divided by 779 is 9 with a remainder of 279.
Put 9 as the next digit of the answer. 
Result so far: 21647.9499
Subtract 7011 from 7290 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Our division results in 21647.9499 with a remaining 0.00279.
