777103 divided by 81 
We're looking to find how many times 81 goes into 777103.

Step 1:
7 divided by 81 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 81

Going ahead to step 2:
81 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 81

Advancing to step 3:
777 divided by 81 is 9 with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 729 from 777 to get 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 81

Step 4:
When dividing 481 by 81, we get 5 with a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 76 after subtracting 405 from 481.
Grab the next digit (0) from the dividend, add it to 76, then carry on: 760 / 81

On to step 5:
760 divided by 81 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 959.0
Deduct 729 from 760 and we're left with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 81

Step 6:
If we divide 313 by 81, we get 3 and a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 9593.0
The remainder is 70 after subtracting 243 from 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
If we divide 700 by 81, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 9593.8
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
If we divide 520 by 81, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 9593.86
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9593.864
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
If we divide 160 by 81, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 9593.8641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 11:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 9593.86419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 12:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 9593.864197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 9593.8641975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
81 goes into 250 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 9593.86419753
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 9593.86419753 with a remainder of 7e-09.
