66389094 divided by 779 
We want to figure out the number of times 66389094 can be divided by 779.

Going ahead to step 1:
6 divided by 779 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 779

Let's proceed to step 2:
When dividing 66 by 779, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 779

On to step 3:
779 can be fit into 663 0 times, resulting in a remainder of 663.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 663 to get 663.
Append the next digit (8) from the dividend to 663 and continue with: 6638 / 779

Let's proceed to step 4:
The number 779 fits into 6638 8 times, leaving a remainder of 406.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6232 from 6638 to get 406.
Append the next digit (9) from the dividend to 406 and continue with: 4069 / 779

On to step 5:
When dividing 4069 by 779, we get 5 with a remainder of 174.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 3895 from 4069 leaves us with 174.
Include the next digit (0) from the dividend after 174, then repeat: 1740 / 779

Moving on to step 6:
The number 779 fits into 1740 2 times, leaving a remainder of 182.
The next digit of our result is 2. 
Result so far: 852.0
Subtract 1558 from 1740 to get 182.
Grab the next digit (9) from the dividend, add it to 182, then carry on: 1829 / 779

Let's proceed to step 7:
779 goes into 1829 2 times with a remainder of 271.
The next digit of our result is 2. 
Result so far: 8522.0
The remainder is 271 after subtracting 1558 from 1829.
Fetch the next digit (4) from the dividend, attach it to 271 and continue: 2714 / 779

Moving on to step 8:
779 goes into 2714 3 times with a remainder of 377.
The next digit of our result is 3. 
Result so far: 85223.0
If we subtract 2337 from 2714, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 9:
The number 779 fits into 3770 4 times, leaving a remainder of 654.
Use 4 as the next digit of our solution. 
Result so far: 85223.4
Subtracting 3116 from 3770 leaves us with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Step 10:
If we divide 6540 by 779, we get 8 and a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 85223.48
Deduct 6232 from 6540 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 11:
779 can be fit into 3080 3 times, resulting in a remainder of 743.
Use 3 as the next digit of our solution. 
Result so far: 85223.483
If we take 2337 away from 3080, we end up with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Step 12:
779 can be fit into 7430 9 times, resulting in a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 85223.4839
If we take 7011 away from 7430, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 13:
The number 779 fits into 4190 5 times, leaving a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 85223.48395
The remainder is 295 after subtracting 3895 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 14:
The number 779 fits into 2950 3 times, leaving a remainder of 613.
Write down 3 as next digit of the result. 
Result so far: 85223.483953
Subtracting 2337 from 2950 leaves us 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.

Let's proceed to step 15:
The number 779 fits into 6130 7 times, leaving a remainder of 677.
Put 7 as the next digit of the answer. 
Result so far: 85223.4839537
Subtract 5453 from 6130 to get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

On to step 16:
When dividing 6770 by 779, we get 8 with a remainder of 538.
Record the quotient 8 as the next digit in the result. 
Result so far: 85223.48395378
If we subtract 6232 from 6770, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

After the division, we end up with 85223.48395378 and a remainder of 5.38e-07.
