66718456 ÷ 771 
We want to divide 66718456 by 771.

Step 1:
If we divide 6 by 771, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 771

Advancing to step 2:
When dividing 66 by 771, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 771

Going ahead to step 3:
If we divide 667 by 771, we get 0 and a remainder of 667.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 667 leaves us with 667.
Fetch the next digit (1) from the dividend, attach it to 667 and continue: 6671 / 771

Going ahead to step 4:
771 goes into 6671 8 times with a remainder of 503.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6168 from 6671 and we're left with 503.
Include the next digit (8) from the dividend after 503, then repeat: 5038 / 771

Going ahead to step 5:
If we divide 5038 by 771, we get 6 and a remainder of 412.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 412 after subtracting 4626 from 5038.
Bring next digit (4) of the dividend behind the 412 and repeat the process: 4124 / 771

Going ahead to step 6:
If we divide 4124 by 771, we get 5 and a remainder of 269.
The next digit of our result is 5. 
Result so far: 865.0
Subtracting 3855 from 4124 leaves us with 269.
Append the next digit (5) from the dividend to 269 and continue with: 2695 / 771

On to step 7:
When dividing 2695 by 771, we get 3 with a remainder of 382.
Use 3 as the next digit of our solution. 
Result so far: 8653.0
The remainder is 382 after subtracting 2313 from 2695.
Append the next digit (6) from the dividend to 382 and continue with: 3826 / 771

Going ahead to step 8:
If we divide 3826 by 771, we get 4 and a remainder of 742.
Write down 4 as next digit of the result. 
Result so far: 86534.0
Subtract 3084 from 3826 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Step 9:
When dividing 7420 by 771, we get 9 with a remainder of 481.
Put 9 as the next digit of the answer. 
Result so far: 86534.9
If we subtract 6939 from 7420, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Moving on to step 10:
When dividing 4810 by 771, we get 6 with a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 86534.96
Subtracting 4626 from 4810 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
1840 divided by 771 is 2 with a remainder of 298.
Put 2 as the next digit of the answer. 
Result so far: 86534.962
Subtracting 1542 from 1840 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 12:
771 can be fit into 2980 3 times, resulting in a remainder of 667.
The number 3 becomes the next digit in our result. 
Result so far: 86534.9623
Subtracting 2313 from 2980 leaves us with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Advancing to step 13:
When dividing 6670 by 771, we get 8 with a remainder of 502.
The number 8 becomes the next digit in our result. 
Result so far: 86534.96238
Subtracting 6168 from 6670 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 14:
The number 771 fits into 5020 6 times, leaving a remainder of 394.
Use 6 as the next digit of our solution. 
Result so far: 86534.962386
Subtracting 4626 from 5020 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 15:
771 can be fit into 3940 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 86534.9623865
If we subtract 3855 from 3940, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 16:
850 divided by 771 is 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 86534.96238651
If we take 771 away from 850, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final outcome is 86534.96238651, with a leftover of 7.9e-08.
