571668 ÷ 81 
We're looking to find how many times 81 goes into 571668.

Step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 81

Moving on to step 2:
If we divide 57 by 81, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 81

Moving on to step 3:
The number 81 fits into 571 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 567 from 571 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 81

Advancing to step 4:
The number 81 fits into 46 0 times, leaving a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 70.0
The remainder is 46 after subtracting 0 from 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 81

Let's proceed to step 5:
466 divided by 81 is 5 with a remainder of 61.
The next digit of our result is 5. 
Result so far: 705.0
Subtracting 405 from 466 leaves us with 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 81

Moving on to step 6:
If we divide 618 by 81, we get 7 and a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 7057.0
The remainder is 51 after subtracting 567 from 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 81, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7057.6
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
When dividing 240 by 81, we get 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 7057.62
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
81 can be fit into 780 9 times, resulting in a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 7057.629
If we take 729 away from 780, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
81 can be fit into 510 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 7057.6296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
The number 81 fits into 240 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 7057.62962
Deduct 162 from 240 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 12:
If we divide 780 by 81, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 7057.629629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 13:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7057.6296296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
240 divided by 81 is 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 7057.62962962
Subtract 162 from 240 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 7057.62962962 with a balance of 7.8e-08.
