We divide 581736 by 81
We want to divide 581736 by 81.

Advancing to step 1:
When dividing 5 by 81, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 81

On to step 2:
The number 81 fits into 58 0 times, leaving a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 81

On to step 3:
When dividing 581 by 81, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 567 away from 581, we end up with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 81

On to step 4:
If we divide 147 by 81, we get 1 and a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 81 from 147 and we're left with 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 81

Going ahead to step 5:
663 divided by 81 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 718.0
If we take 648 away from 663, we end up with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 81

Step 6:
81 goes into 156 1 times with a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 7181.0
The remainder is 75 after subtracting 81 from 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 7:
81 goes into 750 9 times with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7181.9
If we take 729 away from 750, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
The number 81 fits into 210 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 7181.92
Subtract 162 from 210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
81 can be fit into 480 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 7181.925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
81 goes into 750 9 times with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7181.9259
If we take 729 away from 750, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
If we divide 210 by 81, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 7181.92592
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
480 divided by 81 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7181.925925
If we subtract 405 from 480, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
When dividing 750 by 81, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 7181.9259259
The remainder is 21 after subtracting 729 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
81 can be fit into 210 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 7181.92592592
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 7181.92592592 with a remainder of 4.8e-08.
