581459 divided by 72 
Let's see how many times 72 fits into 581459.

Going ahead to step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 72

Moving on to step 2:
The number 72 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 72

On to step 3:
If we divide 581 by 72, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 5 after subtracting 576 from 581.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 72

On to step 4:
54 divided by 72 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 54, we get 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 72

Going ahead to step 5:
When dividing 545 by 72, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 807.0
The remainder is 41 after subtracting 504 from 545.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 72

Moving on to step 6:
72 goes into 419 5 times with a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 8075.0
The remainder is 59 after subtracting 360 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
If we divide 590 by 72, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8075.8
The remainder is 14 after subtracting 576 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
140 divided by 72 is 1 with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 8075.81
Subtract 72 from 140 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
72 goes into 680 9 times with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 8075.819
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
72 goes into 320 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 8075.8194
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
72 goes into 320 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 8075.81944
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 8075.81944 and a remainder of 3.2e-05.
