87232946 divided by 509 
Our goal is to divide 87232946 by 509.

Let's proceed to step 1:
509 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 509

On to step 2:
509 can be fit into 87 0 times, resulting in a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Bring next digit (2) of the dividend behind the 87 and repeat the process: 872 / 509

On to step 3:
509 goes into 872 1 times with a remainder of 363.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 509 from 872 to get 363.
Bring next digit (3) of the dividend behind the 363 and repeat the process: 3633 / 509

Step 4:
3633 divided by 509 is 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3563 away from 3633, we end up with 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 509

Step 5:
If we divide 702 by 509, we get 1 and a remainder of 193.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Deduct 509 from 702 and we're left with 193.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 509

Going ahead to step 6:
509 can be fit into 1939 3 times, resulting in a remainder of 412.
Record the quotient 3 as the next digit in the result. 
Result so far: 1713.0
Deduct 1527 from 1939 and we're left with 412.
Take the next digit (4) from the dividend and append it to 412, then repeat: 4124 / 509

On to step 7:
4124 divided by 509 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 17138.0
If we subtract 4072 from 4124, we get 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 509

Let's proceed to step 8:
The number 509 fits into 526 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 171381.0
The remainder is 17 after subtracting 509 from 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
509 can be fit into 170 0 times, resulting in a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 171381.0
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
The number 509 fits into 1700 3 times, leaving a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 171381.03
Deduct 1527 from 1700 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 11:
509 goes into 1730 3 times with a remainder of 203.
The next digit of our result is 3. 
Result so far: 171381.033
If we take 1527 away from 1730, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Our division results in 171381.033 with a remaining 0.0203.
