We divide 580735 by 81
We're looking to find how many times 81 goes into 580735.

Advancing to step 1:
5 divided by 81 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 81

On to step 2:
81 can be fit into 58 0 times, resulting in a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 81

Advancing to step 3:
580 divided by 81 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 567 from 580 and we're left with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 81

Step 4:
81 can be fit into 137 1 times, resulting in a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 81 from 137 and we're left with 56.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 81

Let's proceed to step 5:
81 goes into 563 6 times with a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 716.0
The remainder is 77 after subtracting 486 from 563.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 81

Advancing to step 6:
775 divided by 81 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 7169.0
If we subtract 729 from 775, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
If we divide 460 by 81, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 7169.5
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
81 goes into 550 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 7169.56
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
The number 81 fits into 640 7 times, leaving a remainder of 73.
The next digit of our result is 7. 
Result so far: 7169.567
Subtracting 567 from 640 leaves us 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 10:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7169.5679
If we subtract 729 from 730, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7169.5679
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
The number 81 fits into 100 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 7169.567901
Subtracting 81 from 100 leaves us 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.

Let's proceed to step 13:
The number 81 fits into 190 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 7169.5679012
Subtracting 162 from 190 leaves us 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.

Step 14:
280 divided by 81 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 7169.56790123
If we subtract 243 from 280, we 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.

The quotient of the division is 7169.56790123, and the remainder is 3.7e-08.
