16579015 ÷ 778 
We want to divide 16579015 by 778.

Let's proceed to step 1:
1 divided by 778 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 778

Advancing to step 2:
The number 778 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 778

Going ahead to step 3:
165 divided by 778 is 0 with a remainder of 165.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 165 to get 165.
Grab the next digit (7) from the dividend, add it to 165, then carry on: 1657 / 778

Step 4:
When dividing 1657 by 778, we get 2 with a remainder of 101.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 101 after subtracting 1556 from 1657.
Bring next digit (9) of the dividend behind the 101 and repeat the process: 1019 / 778

Moving on to step 5:
778 goes into 1019 1 times with a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 778 away from 1019, we end up with 241.
Bring next digit (0) of the dividend behind the 241 and repeat the process: 2410 / 778

Going ahead to step 6:
2410 divided by 778 is 3 with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
Deduct 2334 from 2410 and we're left with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 778

Let's proceed to step 7:
If we divide 761 by 778, we get 0 and a remainder of 761.
Use 0 as the next digit of our solution. 
Result so far: 2130.0
If we subtract 0 from 761, we get 761.
Fetch the next digit (5) from the dividend, attach it to 761 and continue: 7615 / 778

On to step 8:
778 can be fit into 7615 9 times, resulting in a remainder of 613.
Use 9 as the next digit of our solution. 
Result so far: 21309.0
If we take 7002 away from 7615, we end up with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

On to step 9:
The number 778 fits into 6130 7 times, leaving a remainder of 684.
Write down 7 as next digit of the result. 
Result so far: 21309.7
Deduct 5446 from 6130 and we're left with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 10:
778 can be fit into 6840 8 times, resulting in a remainder of 616.
Put 8 as the next digit of the answer. 
Result so far: 21309.78
Subtracting 6224 from 6840 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 11:
When dividing 6160 by 778, we get 7 with a remainder of 714.
The number 7 becomes the next digit in our result. 
Result so far: 21309.787
If we subtract 5446 from 6160, we get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

On to step 12:
778 goes into 7140 9 times with a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 21309.7879
Subtract 7002 from 7140 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 13:
1380 divided by 778 is 1 with a remainder of 602.
Record the quotient 1 as the next digit in the result. 
Result so far: 21309.78791
The remainder is 602 after subtracting 778 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 14:
If we divide 6020 by 778, we get 7 and a remainder of 574.
The next digit of our result is 7. 
Result so far: 21309.787917
If we subtract 5446 from 6020, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 15:
When dividing 5740 by 778, we get 7 with a remainder of 294.
The next digit of our result is 7. 
Result so far: 21309.7879177
If we take 5446 away from 5740, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The final outcome is 21309.7879177, with a leftover of 2.94e-06.
