Let's divide 19923732 by 509
Let's see how many times 509 fits into 19923732.

Moving on to step 1:
The number 509 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 509

Advancing to step 2:
509 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 509

Step 3:
When dividing 199 by 509, we get 0 with a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Grab the next digit (2) from the dividend, add it to 199, then carry on: 1992 / 509

Moving on to step 4:
1992 divided by 509 is 3 with a remainder of 465.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1527 away from 1992, we end up with 465.
Bring next digit (3) of the dividend behind the 465 and repeat the process: 4653 / 509

Advancing to step 5:
509 can be fit into 4653 9 times, resulting in a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 4581 from 4653, we get 72.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 509

Going ahead to step 6:
The number 509 fits into 727 1 times, leaving a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
If we subtract 509 from 727, we get 218.
Take the next digit (3) from the dividend and append it to 218, then repeat: 2183 / 509

On to step 7:
509 can be fit into 2183 4 times, resulting in a remainder of 147.
Use 4 as the next digit of our solution. 
Result so far: 3914.0
Subtract 2036 from 2183 to get 147.
Append the next digit (2) from the dividend to 147 and continue with: 1472 / 509

Let's proceed to step 8:
If we divide 1472 by 509, we get 2 and a remainder of 454.
Put 2 as the next digit of the answer. 
Result so far: 39142.0
Subtract 1018 from 1472 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 9:
509 goes into 4540 8 times with a remainder of 468.
Put 8 as the next digit of the answer. 
Result so far: 39142.8
If we subtract 4072 from 4540, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 10:
If we divide 4680 by 509, we get 9 and a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 39142.89
If we subtract 4581 from 4680, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 11:
509 goes into 990 1 times with a remainder of 481.
The number 1 becomes the next digit in our result. 
Result so far: 39142.891
Subtracting 509 from 990 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 12:
If we divide 4810 by 509, we get 9 and a remainder of 229.
The number 9 becomes the next digit in our result. 
Result so far: 39142.8919
Deduct 4581 from 4810 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 13:
2290 divided by 509 is 4 with a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 39142.89194
Deduct 2036 from 2290 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 14:
509 goes into 2540 4 times with a remainder of 504.
Record the quotient 4 as the next digit in the result. 
Result so far: 39142.891944
If we take 2036 away from 2540, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final result is 39142.891944 with a remainder of 5.04e-05.
