771840 ÷ 99 
We want to divide 771840 by 99.

Going ahead to step 1:
If we divide 7 by 99, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 99

On to step 2:
77 divided by 99 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 99

Going ahead to step 3:
771 divided by 99 is 7 with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 693 from 771, we get 78.
Append the next digit (8) from the dividend to 78 and continue with: 788 / 99

Advancing to step 4:
788 divided by 99 is 7 with a remainder of 95.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 693 from 788 leaves us with 95.
Take the next digit (4) from the dividend and append it to 95, then repeat: 954 / 99

Moving on to step 5:
The number 99 fits into 954 9 times, leaving a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 779.0
Deduct 891 from 954 and we're left with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 99

Moving on to step 6:
99 goes into 630 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 7796.0
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
99 goes into 360 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 7796.3
If we take 297 away from 360, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
99 goes into 630 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 7796.36
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
99 goes into 360 3 times with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 7796.363
Subtract 297 from 360 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 10:
99 goes into 630 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 7796.3636
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
99 goes into 360 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 7796.36363
Subtract 297 from 360 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
99 goes into 630 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 7796.363636
If we take 594 away from 630, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
If we divide 360 by 99, we get 3 and a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 7796.3636363
The remainder is 63 after subtracting 297 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
99 goes into 630 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 7796.36363636
If we subtract 594 from 630, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 7796.36363636 and a remainder of 3.6e-08.
