91782090 ÷ 771 
Our goal is to divide 91782090 by 771.

Step 1:
If we divide 9 by 771, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 771

Step 2:
When dividing 91 by 771, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 771

Moving on to step 3:
If we divide 917 by 771, we get 1 and a remainder of 146.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 771 from 917 and we're left with 146.
Include the next digit (8) from the dividend after 146, then repeat: 1468 / 771

Moving on to step 4:
771 goes into 1468 1 times with a remainder of 697.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 771 from 1468 and we're left with 697.
Bring next digit (2) of the dividend behind the 697 and repeat the process: 6972 / 771

Going ahead to step 5:
771 can be fit into 6972 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Deduct 6939 from 6972 and we're left with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 771

Going ahead to step 6:
771 goes into 330 0 times with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 1190.0
If we take 0 away from 330, we end up with 330.
Fetch the next digit (9) from the dividend, attach it to 330 and continue: 3309 / 771

Step 7:
771 can be fit into 3309 4 times, resulting in a remainder of 225.
The number 4 becomes the next digit in our result. 
Result so far: 11904.0
The remainder is 225 after subtracting 3084 from 3309.
Append the next digit (0) from the dividend to 225 and continue with: 2250 / 771

On to step 8:
If we divide 2250 by 771, we get 2 and a remainder of 708.
Write down 2 as next digit of the result. 
Result so far: 119042.0
If we take 1542 away from 2250, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 9:
7080 divided by 771 is 9 with a remainder of 141.
The next digit of our result is 9. 
Result so far: 119042.9
If we take 6939 away from 7080, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 10:
1410 divided by 771 is 1 with a remainder of 639.
Record the quotient 1 as the next digit in the result. 
Result so far: 119042.91
Subtracting 771 from 1410 leaves us with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Moving on to step 11:
771 goes into 6390 8 times with a remainder of 222.
Write down 8 as next digit of the result. 
Result so far: 119042.918
If we subtract 6168 from 6390, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 12:
The number 771 fits into 2220 2 times, leaving a remainder of 678.
Use 2 as the next digit of our solution. 
Result so far: 119042.9182
If we subtract 1542 from 2220, we get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Step 13:
771 goes into 6780 8 times with a remainder of 612.
Put 8 as the next digit of the answer. 
Result so far: 119042.91828
If we take 6168 away from 6780, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 14:
6120 divided by 771 is 7 with a remainder of 723.
Write down 7 as next digit of the result. 
Result so far: 119042.918287
If we take 5397 away from 6120, we end up with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Moving on to step 15:
7230 divided by 771 is 9 with a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 119042.9182879
The remainder is 291 after subtracting 6939 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 16:
The number 771 fits into 2910 3 times, leaving a remainder of 597.
The next digit of our result is 3. 
Result so far: 119042.91828793
If we subtract 2313 from 2910, we get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

After the division, we end up with 119042.91828793 and a remainder of 5.97e-07.
