We're dividing 77191839 by 817 
We're looking to find how many times 817 goes into 77191839.

Let's proceed to step 1:
7 divided by 817 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 817

Moving on to step 2:
817 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 817

Let's proceed to step 3:
817 goes into 771 0 times with a remainder of 771.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 771, we end up with 771.
Append the next digit (9) from the dividend to 771 and continue with: 7719 / 817

Let's proceed to step 4:
817 goes into 7719 9 times with a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 366 after subtracting 7353 from 7719.
Grab the next digit (1) from the dividend, add it to 366, then carry on: 3661 / 817

Let's proceed to step 5:
The number 817 fits into 3661 4 times, leaving a remainder of 393.
Use 4 as the next digit of our solution. 
Result so far: 94.0
The remainder is 393 after subtracting 3268 from 3661.
Take the next digit (8) from the dividend and append it to 393, then repeat: 3938 / 817

Step 6:
817 goes into 3938 4 times with a remainder of 670.
The number 4 becomes the next digit in our result. 
Result so far: 944.0
If we take 3268 away from 3938, we end up with 670.
Include the next digit (3) from the dividend after 670, then repeat: 6703 / 817

Going ahead to step 7:
The number 817 fits into 6703 8 times, leaving a remainder of 167.
The number 8 becomes the next digit in our result. 
Result so far: 9448.0
Subtracting 6536 from 6703 leaves us with 167.
Fetch the next digit (9) from the dividend, attach it to 167 and continue: 1679 / 817

On to step 8:
817 can be fit into 1679 2 times, resulting in a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 94482.0
Subtracting 1634 from 1679 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
817 goes into 450 0 times with a remainder of 450.
The next digit of our result is 0. 
Result so far: 94482.0
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
4500 divided by 817 is 5 with a remainder of 415.
Use 5 as the next digit of our solution. 
Result so far: 94482.05
Subtracting 4085 from 4500 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 11:
4150 divided by 817 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 94482.055
Deduct 4085 from 4150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 94482.055, with a leftover of 0.0065.
