20856481 divided by 509 
We're looking to find how many times 509 goes into 20856481.

Advancing to step 1:
509 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 509

Let's proceed to step 2:
509 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 509

Let's proceed to step 3:
When dividing 208 by 509, we get 0 with a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 208 leaves us with 208.
Take the next digit (5) from the dividend and append it to 208, then repeat: 2085 / 509

Moving on to step 4:
2085 divided by 509 is 4 with a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 49 after subtracting 2036 from 2085.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 509

On to step 5:
509 goes into 496 0 times with a remainder of 496.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 496, we end up with 496.
Grab the next digit (4) from the dividend, add it to 496, then carry on: 4964 / 509

Moving on to step 6:
4964 divided by 509 is 9 with a remainder of 383.
The next digit of our result is 9. 
Result so far: 409.0
If we subtract 4581 from 4964, we get 383.
Bring next digit (8) of the dividend behind the 383 and repeat the process: 3838 / 509

Moving on to step 7:
509 goes into 3838 7 times with a remainder of 275.
Put 7 as the next digit of the answer. 
Result so far: 4097.0
If we subtract 3563 from 3838, we get 275.
Grab the next digit (1) from the dividend, add it to 275, then carry on: 2751 / 509

Advancing to step 8:
509 goes into 2751 5 times with a remainder of 206.
Write down 5 as next digit of the result. 
Result so far: 40975.0
The remainder is 206 after subtracting 2545 from 2751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 9:
When dividing 2060 by 509, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 40975.4
Subtracting 2036 from 2060 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 509, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 40975.4
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
If we divide 2400 by 509, we get 4 and a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 40975.404
If we subtract 2036 from 2400, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 12:
If we divide 3640 by 509, we get 7 and a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 40975.4047
If we subtract 3563 from 3640, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 13:
509 can be fit into 770 1 times, resulting in a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 40975.40471
If we subtract 509 from 770, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 14:
The number 509 fits into 2610 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 40975.404715
The remainder is 65 after subtracting 2545 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 15:
650 divided by 509 is 1 with a remainder of 141.
The next digit of our result is 1. 
Result so far: 40975.4047151
The remainder is 141 after subtracting 509 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 16:
If we divide 1410 by 509, we get 2 and a remainder of 392.
Put 2 as the next digit of the answer. 
Result so far: 40975.40471512
Subtract 1018 from 1410 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 40975.40471512, with a leftover of 3.92e-07.
