521995 divided by 77 
We're looking to find how many times 77 goes into 521995.

Going ahead to step 1:
77 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 77

Step 2:
77 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 77

Moving on to step 3:
521 divided by 77 is 6 with a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 59 after subtracting 462 from 521.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 77

Let's proceed to step 4:
The number 77 fits into 599 7 times, leaving a remainder of 60.
The next digit of our result is 7. 
Result so far: 67.0
If we take 539 away from 599, we end up with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 77

Let's proceed to step 5:
If we divide 609 by 77, we get 7 and a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 677.0
Subtracting 539 from 609 leaves us with 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 77

Let's proceed to step 6:
77 goes into 705 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 6779.0
Subtract 693 from 705 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
When dividing 120 by 77, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 6779.1
If we take 77 away from 120, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
If we divide 430 by 77, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 6779.15
Subtracting 385 from 430 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:
When dividing 450 by 77, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 6779.155
If we subtract 385 from 450, we get 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 result is 6779.155 with a remainder of 0.0065.
