We divide 66647528 by 509
We want to divide 66647528 by 509.

Advancing to step 1:
If we divide 6 by 509, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 509

Advancing to step 2:
509 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 509

On to step 3:
When dividing 666 by 509, we get 1 with a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 509 from 666 to get 157.
Take the next digit (4) from the dividend and append it to 157, then repeat: 1574 / 509

Let's proceed to step 4:
1574 divided by 509 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1527 from 1574 to get 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 509

On to step 5:
509 goes into 477 0 times with a remainder of 477.
The next digit of our result is 0. 
Result so far: 130.0
If we subtract 0 from 477, we get 477.
Bring next digit (5) of the dividend behind the 477 and repeat the process: 4775 / 509

Let's proceed to step 6:
The number 509 fits into 4775 9 times, leaving a remainder of 194.
Record the quotient 9 as the next digit in the result. 
Result so far: 1309.0
The remainder is 194 after subtracting 4581 from 4775.
Append the next digit (2) from the dividend to 194 and continue with: 1942 / 509

Going ahead to step 7:
509 can be fit into 1942 3 times, resulting in a remainder of 415.
Write down 3 as next digit of the result. 
Result so far: 13093.0
If we subtract 1527 from 1942, we get 415.
Include the next digit (8) from the dividend after 415, then repeat: 4158 / 509

On to step 8:
509 goes into 4158 8 times with a remainder of 86.
The next digit of our result is 8. 
Result so far: 130938.0
Subtracting 4072 from 4158 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
The number 509 fits into 860 1 times, leaving a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 130938.1
Subtracting 509 from 860 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 10:
509 can be fit into 3510 6 times, resulting in a remainder of 456.
Write down 6 as next digit of the result. 
Result so far: 130938.16
Subtract 3054 from 3510 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 11:
When dividing 4560 by 509, we get 8 with a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 130938.168
Subtract 4072 from 4560 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 12:
The number 509 fits into 4880 9 times, leaving a remainder of 299.
Write down 9 as next digit of the result. 
Result so far: 130938.1689
Deduct 4581 from 4880 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 13:
2990 divided by 509 is 5 with a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 130938.16895
Subtracting 2545 from 2990 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 14:
When dividing 4450 by 509, we get 8 with a remainder of 378.
The next digit of our result is 8. 
Result so far: 130938.168958
Subtract 4072 from 4450 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 15:
When dividing 3780 by 509, we get 7 with a remainder of 217.
Record the quotient 7 as the next digit in the result. 
Result so far: 130938.1689587
Deduct 3563 from 3780 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 16:
2170 divided by 509 is 4 with a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 130938.16895874
If we subtract 2036 from 2170, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

In conclusion, the division gives 130938.16895874 with a balance of 1.34e-07.
