578077 divided by 81 
We want to divide 578077 by 81.

Advancing to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 81

Advancing to step 2:
81 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 81

Moving on to step 3:
The number 81 fits into 578 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 567 from 578 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 81

On to step 4:
110 divided by 81 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 81 from 110, we get 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 81

On to step 5:
If we divide 297 by 81, we get 3 and a remainder of 54.
The next digit of our result is 3. 
Result so far: 713.0
Subtracting 243 from 297 leaves us with 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 81

On to step 6:
If we divide 547 by 81, we get 6 and a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 7136.0
The remainder is 61 after subtracting 486 from 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
610 divided by 81 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 7136.7
Deduct 567 from 610 and we're left with 43.
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 8:
81 can be fit into 430 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7136.75
Deduct 405 from 430 and we're left with 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 9:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 7136.753
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 7136.753
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 81, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 7136.75308
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.

Let's proceed to step 12:
If we divide 520 by 81, we get 6 and a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 7136.753086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
81 can be fit into 340 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7136.7530864
Deduct 324 from 340 and we're left 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.

Step 14:
If we divide 160 by 81, we get 1 and a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 7136.75308641
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.

The final result is 7136.75308641 with a remainder of 7.9e-08.
