We look at the division of 66019 by 77 
Let's see how many times 77 fits into 66019.

Step 1:
77 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 77

Step 2:
66 divided by 77 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 77

Step 3:
When dividing 660 by 77, we get 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 616 away from 660, we end up with 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 77

On to step 4:
441 divided by 77 is 5 with a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtract 385 from 441 to get 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 77

Let's proceed to step 5:
When dividing 569 by 77, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 857.0
If we take 539 away from 569, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 6:
300 divided by 77 is 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 857.3
The remainder is 69 after subtracting 231 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 7:
77 goes into 690 8 times with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 857.38
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
77 can be fit into 740 9 times, resulting in a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 857.389
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
When dividing 470 by 77, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 857.3896
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
77 can be fit into 80 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 857.38961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 857.38961
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
300 divided by 77 is 3 with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 857.3896103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 13:
77 goes into 690 8 times with a remainder of 74.
The next digit of our result is 8. 
Result so far: 857.38961038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 857.38961038 with a remainder of 7.4e-08.
