509109 divided by 72 
We want to divide 509109 by 72.

On to step 1:
72 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 72

On to step 2:
When dividing 50 by 72, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 72

Moving on to step 3:
When dividing 509 by 72, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 504 from 509 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 72

On to step 4:
When dividing 51 by 72, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we subtract 0 from 51, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 72

Advancing to step 5:
72 goes into 510 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 707.0
If we take 504 away from 510, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 72

Advancing to step 6:
69 divided by 72 is 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 7070.0
Subtracting 0 from 69 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
If we divide 690 by 72, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 7070.9
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
420 divided by 72 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7070.95
Subtract 360 from 420 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 72, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 7070.958
Subtract 576 from 600 to 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.

Step 10:
240 divided by 72 is 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 7070.9583
Subtracting 216 from 240 leaves us 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.

Moving on to step 11:
240 divided by 72 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 7070.95833
Deduct 216 from 240 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.

The final outcome is 7070.95833, with a leftover of 2.4e-05.
