Let's divide 9639787 by 779
We're looking to find how many times 779 goes into 9639787.

Advancing to step 1:
When dividing 9 by 779, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 779

Moving on to step 2:
779 goes into 96 0 times with a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 96, we get 96.
Fetch the next digit (3) from the dividend, attach it to 96 and continue: 963 / 779

Let's proceed to step 3:
When dividing 963 by 779, we get 1 with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 779 from 963 leaves us with 184.
Fetch the next digit (9) from the dividend, attach it to 184 and continue: 1849 / 779

Step 4:
1849 divided by 779 is 2 with a remainder of 291.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 291 after subtracting 1558 from 1849.
Take the next digit (7) from the dividend and append it to 291, then repeat: 2917 / 779

On to step 5:
If we divide 2917 by 779, we get 3 and a remainder of 580.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 2337 from 2917 leaves us with 580.
Bring next digit (8) of the dividend behind the 580 and repeat the process: 5808 / 779

Advancing to step 6:
If we divide 5808 by 779, we get 7 and a remainder of 355.
The number 7 becomes the next digit in our result. 
Result so far: 1237.0
Subtracting 5453 from 5808 leaves us with 355.
Bring next digit (7) of the dividend behind the 355 and repeat the process: 3557 / 779

Advancing to step 7:
779 can be fit into 3557 4 times, resulting in a remainder of 441.
The number 4 becomes the next digit in our result. 
Result so far: 12374.0
Subtract 3116 from 3557 to get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

On to step 8:
779 goes into 4410 5 times with a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 12374.5
Deduct 3895 from 4410 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 9:
When dividing 5150 by 779, we get 6 with a remainder of 476.
Put 6 as the next digit of the answer. 
Result so far: 12374.56
Subtract 4674 from 5150 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 10:
4760 divided by 779 is 6 with a remainder of 86.
The number 6 becomes the next digit in our result. 
Result so far: 12374.566
Subtracting 4674 from 4760 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 12374.566 with a remainder of 0.0086.
