We look at the division of 66809569 by 779 
Let's see how many times 779 fits into 66809569.

Moving on to step 1:
If we divide 6 by 779, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 779

Step 2:
The number 779 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 779

Advancing to step 3:
If we divide 668 by 779, we get 0 and a remainder of 668.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 668, we get 668.
Append the next digit (0) from the dividend to 668 and continue with: 6680 / 779

Advancing to step 4:
The number 779 fits into 6680 8 times, leaving a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 448 after subtracting 6232 from 6680.
Bring next digit (9) of the dividend behind the 448 and repeat the process: 4489 / 779

Going ahead to step 5:
4489 divided by 779 is 5 with a remainder of 594.
Use 5 as the next digit of our solution. 
Result so far: 85.0
The remainder is 594 after subtracting 3895 from 4489.
Include the next digit (5) from the dividend after 594, then repeat: 5945 / 779

Going ahead to step 6:
5945 divided by 779 is 7 with a remainder of 492.
Put 7 as the next digit of the answer. 
Result so far: 857.0
Subtracting 5453 from 5945 leaves us with 492.
Grab the next digit (6) from the dividend, add it to 492, then carry on: 4926 / 779

Advancing to step 7:
779 goes into 4926 6 times with a remainder of 252.
The next digit of our result is 6. 
Result so far: 8576.0
Deduct 4674 from 4926 and we're left with 252.
Take the next digit (9) from the dividend and append it to 252, then repeat: 2529 / 779

Going ahead to step 8:
779 can be fit into 2529 3 times, resulting in a remainder of 192.
The next digit of our result is 3. 
Result so far: 85763.0
If we take 2337 away from 2529, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 9:
When dividing 1920 by 779, we get 2 with a remainder of 362.
Record the quotient 2 as the next digit in the result. 
Result so far: 85763.2
Subtracting 1558 from 1920 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 10:
779 goes into 3620 4 times with a remainder of 504.
Write down 4 as next digit of the result. 
Result so far: 85763.24
Subtract 3116 from 3620 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 11:
5040 divided by 779 is 6 with a remainder of 366.
Use 6 as the next digit of our solution. 
Result so far: 85763.246
If we take 4674 away from 5040, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 12:
3660 divided by 779 is 4 with a remainder of 544.
Write down 4 as next digit of the result. 
Result so far: 85763.2464
Subtract 3116 from 3660 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 13:
The number 779 fits into 5440 6 times, leaving a remainder of 766.
The number 6 becomes the next digit in our result. 
Result so far: 85763.24646
If we subtract 4674 from 5440, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Let's proceed to step 14:
When dividing 7660 by 779, we get 9 with a remainder of 649.
Write down 9 as next digit of the result. 
Result so far: 85763.246469
Deduct 7011 from 7660 and we're left with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Going ahead to step 15:
If we divide 6490 by 779, we get 8 and a remainder of 258.
The next digit of our result is 8. 
Result so far: 85763.2464698
If we subtract 6232 from 6490, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 16:
2580 divided by 779 is 3 with a remainder of 243.
Use 3 as the next digit of our solution. 
Result so far: 85763.24646983
Deduct 2337 from 2580 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

In conclusion, the division gives 85763.24646983 with a balance of 2.43e-07.
