77518261 ÷ 771 
Let's see how many times 771 fits into 77518261.

Moving on to step 1:
The number 771 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 771

Step 2:
77 divided by 771 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 771

Advancing to step 3:
When dividing 775 by 771, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 771 away from 775, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 771

Moving on to step 4:
771 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 41, we end up with 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 771

On to step 5:
When dividing 418 by 771, we get 0 with a remainder of 418.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 418 leaves us with 418.
Include the next digit (2) from the dividend after 418, then repeat: 4182 / 771

Moving on to step 6:
When dividing 4182 by 771, we get 5 with a remainder of 327.
The number 5 becomes the next digit in our result. 
Result so far: 1005.0
Subtracting 3855 from 4182 leaves us with 327.
Append the next digit (6) from the dividend to 327 and continue with: 3276 / 771

Step 7:
771 goes into 3276 4 times with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 10054.0
If we take 3084 away from 3276, we end up with 192.
Bring next digit (1) of the dividend behind the 192 and repeat the process: 1921 / 771

Advancing to step 8:
771 can be fit into 1921 2 times, resulting in a remainder of 379.
The number 2 becomes the next digit in our result. 
Result so far: 100542.0
Deduct 1542 from 1921 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 9:
When dividing 3790 by 771, we get 4 with a remainder of 706.
Put 4 as the next digit of the answer. 
Result so far: 100542.4
Subtracting 3084 from 3790 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Advancing to step 10:
When dividing 7060 by 771, we get 9 with a remainder of 121.
The next digit of our result is 9. 
Result so far: 100542.49
The remainder is 121 after subtracting 6939 from 7060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 11:
When dividing 1210 by 771, we get 1 with a remainder of 439.
Write down 1 as next digit of the result. 
Result so far: 100542.491
Subtract 771 from 1210 to get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 12:
771 goes into 4390 5 times with a remainder of 535.
Use 5 as the next digit of our solution. 
Result so far: 100542.4915
If we subtract 3855 from 4390, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 13:
771 goes into 5350 6 times with a remainder of 724.
Write down 6 as next digit of the result. 
Result so far: 100542.49156
Subtract 4626 from 5350 to get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Going ahead to step 14:
The number 771 fits into 7240 9 times, leaving a remainder of 301.
Put 9 as the next digit of the answer. 
Result so far: 100542.491569
If we take 6939 away from 7240, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 15:
If we divide 3010 by 771, we get 3 and a remainder of 697.
Put 3 as the next digit of the answer. 
Result so far: 100542.4915693
If we take 2313 away from 3010, we end up with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Let's proceed to step 16:
6970 divided by 771 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 100542.49156939
Deduct 6939 from 6970 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 100542.49156939 with a balance of 3.1e-08.
