We look at the division of 19536399 by 779 
We want to divide 19536399 by 779.

Moving on to step 1:
The number 779 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 779

Moving on to step 2:
The number 779 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 779

On to step 3:
When dividing 195 by 779, we get 0 with a remainder of 195.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 195, we end up with 195.
Grab the next digit (3) from the dividend, add it to 195, then carry on: 1953 / 779

Step 4:
779 goes into 1953 2 times with a remainder of 395.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 395 after subtracting 1558 from 1953.
Include the next digit (6) from the dividend after 395, then repeat: 3956 / 779

Step 5:
If we divide 3956 by 779, we get 5 and a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 3895 from 3956 to get 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 779

On to step 6:
If we divide 613 by 779, we get 0 and a remainder of 613.
Put 0 as the next digit of the answer. 
Result so far: 250.0
If we take 0 away from 613, we end up with 613.
Grab the next digit (9) from the dividend, add it to 613, then carry on: 6139 / 779

On to step 7:
When dividing 6139 by 779, we get 7 with a remainder of 686.
Use 7 as the next digit of our solution. 
Result so far: 2507.0
If we take 5453 away from 6139, we end up with 686.
Grab the next digit (9) from the dividend, add it to 686, then carry on: 6869 / 779

Step 8:
The number 779 fits into 6869 8 times, leaving a remainder of 637.
The number 8 becomes the next digit in our result. 
Result so far: 25078.0
Subtract 6232 from 6869 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Moving on to step 9:
When dividing 6370 by 779, we get 8 with a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 25078.8
Subtract 6232 from 6370 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.

Going ahead to step 10:
The number 779 fits into 1380 1 times, leaving a remainder of 601.
The number 1 becomes the next digit in our result. 
Result so far: 25078.81
If we subtract 779 from 1380, we get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 11:
779 can be fit into 6010 7 times, resulting in a remainder of 557.
Record the quotient 7 as the next digit in the result. 
Result so far: 25078.817
The remainder is 557 after subtracting 5453 from 6010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Going ahead to step 12:
The number 779 fits into 5570 7 times, leaving a remainder of 117.
The next digit of our result is 7. 
Result so far: 25078.8177
If we take 5453 away from 5570, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final result is 25078.8177 with a remainder of 0.00117.
