We look at the division of 77088758 by 81 
We're looking to find how many times 81 goes into 77088758.

On to step 1:
7 divided by 81 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 81

Advancing to step 2:
81 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 81

Advancing to step 3:
81 goes into 770 9 times with a remainder of 41.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 729 from 770 to get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 81

Let's proceed to step 4:
If we divide 418 by 81, we get 5 and a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtracting 405 from 418 leaves us with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 81

Moving on to step 5:
81 can be fit into 138 1 times, resulting in a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 951.0
Subtract 81 from 138 to get 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 81

Moving on to step 6:
577 divided by 81 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 9517.0
If we take 567 away from 577, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 81

Moving on to step 7:
81 goes into 105 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 95171.0
Subtract 81 from 105 to get 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 81

Step 8:
When dividing 248 by 81, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 951713.0
Subtract 243 from 248 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 81 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 951713.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
81 goes into 500 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 951713.06
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
When dividing 140 by 81, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 951713.061
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
81 goes into 590 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 951713.0617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
When dividing 230 by 81, we get 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 951713.06172
Subtracting 162 from 230 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
81 can be fit into 680 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 951713.061728
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
The number 81 fits into 320 3 times, leaving a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 951713.0617283
If we subtract 243 from 320, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 16:
The number 81 fits into 770 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 951713.06172839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 951713.06172839, with a leftover of 4.1e-08.
