Let's divide 77581 by 81
Let's see how many times 81 fits into 77581.

Moving on to step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 81

Advancing to step 2:
77 divided by 81 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 81

On to step 3:
The number 81 fits into 775 9 times, leaving a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 46 after subtracting 729 from 775.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 81

Step 4:
81 can be fit into 468 5 times, resulting in a remainder of 63.
The next digit of our result is 5. 
Result so far: 95.0
Deduct 405 from 468 and we're left with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 81

Going ahead to step 5:
When dividing 631 by 81, we get 7 with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 957.0
If we subtract 567 from 631, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 6:
The number 81 fits into 640 7 times, leaving a remainder of 73.
The next digit of our result is 7. 
Result so far: 957.7
If we take 567 away from 640, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 957.79
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 957.79
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 81, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 957.7901
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
When dividing 190 by 81, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 957.79012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
81 can be fit into 280 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 957.790123
Subtract 243 from 280 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
When dividing 370 by 81, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 957.7901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
When dividing 460 by 81, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 957.79012345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 957.79012345 with a remainder of 5.5e-08.
