We're dividing 70727739 by 509 
We want to divide 70727739 by 509.

Step 1:
7 divided by 509 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 509

Moving on to step 2:
509 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 509

On to step 3:
The number 509 fits into 707 1 times, leaving a remainder of 198.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 509 away from 707, we end up with 198.
Append the next digit (2) from the dividend to 198 and continue with: 1982 / 509

Step 4:
509 can be fit into 1982 3 times, resulting in a remainder of 455.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1527 from 1982, we get 455.
Take the next digit (7) from the dividend and append it to 455, then repeat: 4557 / 509

Going ahead to step 5:
When dividing 4557 by 509, we get 8 with a remainder of 485.
The next digit of our result is 8. 
Result so far: 138.0
If we take 4072 away from 4557, we end up with 485.
Bring next digit (7) of the dividend behind the 485 and repeat the process: 4857 / 509

Step 6:
The number 509 fits into 4857 9 times, leaving a remainder of 276.
The number 9 becomes the next digit in our result. 
Result so far: 1389.0
The remainder is 276 after subtracting 4581 from 4857.
Bring next digit (3) of the dividend behind the 276 and repeat the process: 2763 / 509

Moving on to step 7:
When dividing 2763 by 509, we get 5 with a remainder of 218.
Put 5 as the next digit of the answer. 
Result so far: 13895.0
The remainder is 218 after subtracting 2545 from 2763.
Bring next digit (9) of the dividend behind the 218 and repeat the process: 2189 / 509

Let's proceed to step 8:
509 can be fit into 2189 4 times, resulting in a remainder of 153.
The number 4 becomes the next digit in our result. 
Result so far: 138954.0
If we subtract 2036 from 2189, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
1530 divided by 509 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 138954.3
The remainder is 3 after subtracting 1527 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
509 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 138954.3
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 509 is 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 138954.3
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 138954.3 with a remaining 0.03.
