We divide 21024803 by 779
We want to figure out the number of times 21024803 can be divided by 779.

On to step 1:
If we divide 2 by 779, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 779

Let's proceed to step 2:
If we divide 21 by 779, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 779

Advancing to step 3:
779 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Take the next digit (2) from the dividend and append it to 210, then repeat: 2102 / 779

Going ahead to step 4:
2102 divided by 779 is 2 with a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1558 from 2102 leaves us with 544.
Include the next digit (4) from the dividend after 544, then repeat: 5444 / 779

On to step 5:
779 goes into 5444 6 times with a remainder of 770.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 770 after subtracting 4674 from 5444.
Grab the next digit (8) from the dividend, add it to 770, then carry on: 7708 / 779

Step 6:
7708 divided by 779 is 9 with a remainder of 697.
Write down 9 as next digit of the result. 
Result so far: 269.0
Deduct 7011 from 7708 and we're left with 697.
Fetch the next digit (0) from the dividend, attach it to 697 and continue: 6970 / 779

On to step 7:
6970 divided by 779 is 8 with a remainder of 738.
Put 8 as the next digit of the answer. 
Result so far: 2698.0
If we subtract 6232 from 6970, we get 738.
Fetch the next digit (3) from the dividend, attach it to 738 and continue: 7383 / 779

On to step 8:
If we divide 7383 by 779, we get 9 and a remainder of 372.
The number 9 becomes the next digit in our result. 
Result so far: 26989.0
If we subtract 7011 from 7383, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 9:
779 can be fit into 3720 4 times, resulting in a remainder of 604.
The number 4 becomes the next digit in our result. 
Result so far: 26989.4
The remainder is 604 after subtracting 3116 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 10:
The number 779 fits into 6040 7 times, leaving a remainder of 587.
Write down 7 as next digit of the result. 
Result so far: 26989.47
Subtracting 5453 from 6040 leaves us with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

On to step 11:
779 can be fit into 5870 7 times, resulting in a remainder of 417.
Use 7 as the next digit of our solution. 
Result so far: 26989.477
If we subtract 5453 from 5870, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

The quotient of the division is 26989.477, and the remainder is 0.0417.
