69886071 divided by 509 
Our goal is to divide 69886071 by 509.

Step 1:
When dividing 6 by 509, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 509

Advancing to step 2:
69 divided by 509 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 509

Going ahead to step 3:
The number 509 fits into 698 1 times, leaving a remainder of 189.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 189 after subtracting 509 from 698.
Bring next digit (8) of the dividend behind the 189 and repeat the process: 1898 / 509

Let's proceed to step 4:
When dividing 1898 by 509, we get 3 with a remainder of 371.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 371 after subtracting 1527 from 1898.
Take the next digit (6) from the dividend and append it to 371, then repeat: 3716 / 509

Let's proceed to step 5:
The number 509 fits into 3716 7 times, leaving a remainder of 153.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 3563 from 3716 and we're left with 153.
Bring next digit (0) of the dividend behind the 153 and repeat the process: 1530 / 509

Moving on to step 6:
509 can be fit into 1530 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1373.0
Deduct 1527 from 1530 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 509

Advancing to step 7:
When dividing 37 by 509, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 13730.0
If we subtract 0 from 37, we get 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 509

Let's proceed to step 8:
371 divided by 509 is 0 with a remainder of 371.
Write down 0 as next digit of the result. 
Result so far: 137300.0
Subtracting 0 from 371 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 9:
The number 509 fits into 3710 7 times, leaving a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 137300.7
Subtracting 3563 from 3710 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 10:
When dividing 1470 by 509, we get 2 with a remainder of 452.
Record the quotient 2 as the next digit in the result. 
Result so far: 137300.72
If we subtract 1018 from 1470, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 11:
The number 509 fits into 4520 8 times, leaving a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 137300.728
Subtract 4072 from 4520 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 12:
509 goes into 4480 8 times with a remainder of 408.
Put 8 as the next digit of the answer. 
Result so far: 137300.7288
If we take 4072 away from 4480, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final result is 137300.7288 with a remainder of 0.00408.
