Let's divide 78995891 by 577
Our goal is to divide 78995891 by 577.

Going ahead to step 1:
577 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 577

On to step 2:
577 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 577

Advancing to step 3:
The number 577 fits into 789 1 times, leaving a remainder of 212.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 212 after subtracting 577 from 789.
Fetch the next digit (9) from the dividend, attach it to 212 and continue: 2129 / 577

Going ahead to step 4:
577 goes into 2129 3 times with a remainder of 398.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1731 from 2129 and we're left with 398.
Take the next digit (5) from the dividend and append it to 398, then repeat: 3985 / 577

Let's proceed to step 5:
577 goes into 3985 6 times with a remainder of 523.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtract 3462 from 3985 to get 523.
Append the next digit (8) from the dividend to 523 and continue with: 5238 / 577

Step 6:
The number 577 fits into 5238 9 times, leaving a remainder of 45.
The next digit of our result is 9. 
Result so far: 1369.0
Subtract 5193 from 5238 to get 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 577

Going ahead to step 7:
The number 577 fits into 459 0 times, leaving a remainder of 459.
Use 0 as the next digit of our solution. 
Result so far: 13690.0
Subtract 0 from 459 to get 459.
Grab the next digit (1) from the dividend, add it to 459, then carry on: 4591 / 577

Let's proceed to step 8:
When dividing 4591 by 577, we get 7 with a remainder of 552.
Record the quotient 7 as the next digit in the result. 
Result so far: 136907.0
Deduct 4039 from 4591 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 9:
When dividing 5520 by 577, we get 9 with a remainder of 327.
Record the quotient 9 as the next digit in the result. 
Result so far: 136907.9
The remainder is 327 after subtracting 5193 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 10:
577 can be fit into 3270 5 times, resulting in a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 136907.95
Deduct 2885 from 3270 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 11:
577 can be fit into 3850 6 times, resulting in a remainder of 388.
Write down 6 as next digit of the result. 
Result so far: 136907.956
Deduct 3462 from 3850 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 12:
577 can be fit into 3880 6 times, resulting in a remainder of 418.
Use 6 as the next digit of our solution. 
Result so far: 136907.9566
Subtracting 3462 from 3880 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 136907.9566, with a leftover of 0.00418.
