We divide 23457643 by 509
We want to divide 23457643 by 509.

Advancing to step 1:
The number 509 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 509

Let's proceed to step 2:
The number 509 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 509

On to step 3:
The number 509 fits into 234 0 times, leaving a remainder of 234.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 234 after subtracting 0 from 234.
Bring next digit (5) of the dividend behind the 234 and repeat the process: 2345 / 509

Moving on to step 4:
The number 509 fits into 2345 4 times, leaving a remainder of 309.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2036 from 2345 and we're left with 309.
Take the next digit (7) from the dividend and append it to 309, then repeat: 3097 / 509

On to step 5:
The number 509 fits into 3097 6 times, leaving a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 3054 from 3097, we get 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 509

Advancing to step 6:
436 divided by 509 is 0 with a remainder of 436.
The next digit of our result is 0. 
Result so far: 460.0
Subtracting 0 from 436 leaves us with 436.
Include the next digit (4) from the dividend after 436, then repeat: 4364 / 509

Moving on to step 7:
The number 509 fits into 4364 8 times, leaving a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 4608.0
Subtracting 4072 from 4364 leaves us with 292.
Fetch the next digit (3) from the dividend, attach it to 292 and continue: 2923 / 509

Going ahead to step 8:
2923 divided by 509 is 5 with a remainder of 378.
Record the quotient 5 as the next digit in the result. 
Result so far: 46085.0
Deduct 2545 from 2923 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 9:
If we divide 3780 by 509, we get 7 and a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 46085.7
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.

Moving on to step 10:
The number 509 fits into 2170 4 times, leaving a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 46085.74
If we take 2036 away from 2170, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 11:
The number 509 fits into 1340 2 times, leaving a remainder of 322.
Record the quotient 2 as the next digit in the result. 
Result so far: 46085.742
If we take 1018 away from 1340, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 12:
509 goes into 3220 6 times with a remainder of 166.
The number 6 becomes the next digit in our result. 
Result so far: 46085.7426
Subtracting 3054 from 3220 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 13:
1660 divided by 509 is 3 with a remainder of 133.
Record the quotient 3 as the next digit in the result. 
Result so far: 46085.74263
If we take 1527 away from 1660, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 14:
1330 divided by 509 is 2 with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 46085.742632
Deduct 1018 from 1330 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 15:
509 can be fit into 3120 6 times, resulting in a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 46085.7426326
If we subtract 3054 from 3120, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 16:
509 can be fit into 660 1 times, resulting in a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 46085.74263261
The remainder is 151 after subtracting 509 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

After the division, we end up with 46085.74263261 and a remainder of 1.51e-07.
