We divide 21842690 by 509
Let's see how many times 509 fits into 21842690.

On to step 1:
509 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 509

Let's proceed to step 2:
21 divided by 509 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 509

Let's proceed to step 3:
509 goes into 218 0 times with a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 218 after subtracting 0 from 218.
Include the next digit (4) from the dividend after 218, then repeat: 2184 / 509

On to step 4:
The number 509 fits into 2184 4 times, leaving a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 148 after subtracting 2036 from 2184.
Include the next digit (2) from the dividend after 148, then repeat: 1482 / 509

Let's proceed to step 5:
509 can be fit into 1482 2 times, resulting in a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 464 after subtracting 1018 from 1482.
Take the next digit (6) from the dividend and append it to 464, then repeat: 4646 / 509

Step 6:
When dividing 4646 by 509, we get 9 with a remainder of 65.
The next digit of our result is 9. 
Result so far: 429.0
The remainder is 65 after subtracting 4581 from 4646.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 509

Step 7:
If we divide 659 by 509, we get 1 and a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 4291.0
The remainder is 150 after subtracting 509 from 659.
Grab the next digit (0) from the dividend, add it to 150, then carry on: 1500 / 509

Advancing to step 8:
509 goes into 1500 2 times with a remainder of 482.
Put 2 as the next digit of the answer. 
Result so far: 42912.0
The remainder is 482 after subtracting 1018 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 9:
The number 509 fits into 4820 9 times, leaving a remainder of 239.
Write down 9 as next digit of the result. 
Result so far: 42912.9
The remainder is 239 after subtracting 4581 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 10:
509 can be fit into 2390 4 times, resulting in a remainder of 354.
The next digit of our result is 4. 
Result so far: 42912.94
The remainder is 354 after subtracting 2036 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 11:
3540 divided by 509 is 6 with a remainder of 486.
The number 6 becomes the next digit in our result. 
Result so far: 42912.946
The remainder is 486 after subtracting 3054 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 12:
The number 509 fits into 4860 9 times, leaving a remainder of 279.
Put 9 as the next digit of the answer. 
Result so far: 42912.9469
Subtracting 4581 from 4860 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 13:
2790 divided by 509 is 5 with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 42912.94695
Subtracting 2545 from 2790 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 14:
The number 509 fits into 2450 4 times, leaving a remainder of 414.
Use 4 as the next digit of our solution. 
Result so far: 42912.946954
If we take 2036 away from 2450, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 15:
4140 divided by 509 is 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 42912.9469548
Subtract 4072 from 4140 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 16:
680 divided by 509 is 1 with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 42912.94695481
If we subtract 509 from 680, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

The final result is 42912.94695481 with a remainder of 1.71e-07.
