Let's divide 23509 by 19
We're looking to find how many times 19 goes into 23509.

Going ahead to step 1:
19 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 19

Advancing to step 2:
The number 19 fits into 23 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 19 from 23 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 19

Let's proceed to step 3:
When dividing 45 by 19, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 38 from 45 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 19

Let's proceed to step 4:
19 goes into 70 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
The remainder is 13 after subtracting 57 from 70.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 19

Going ahead to step 5:
If we divide 139 by 19, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1237.0
If we subtract 133 from 139, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
60 divided by 19 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 1237.3
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 19, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1237.31
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
19 can be fit into 110 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 1237.315
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
When dividing 150 by 19, we get 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 1237.3157
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
If we divide 170 by 19, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 1237.31578
Deduct 152 from 170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
If we divide 180 by 19, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 1237.315789
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
90 divided by 19 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 1237.3157894
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
19 goes into 140 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1237.31578947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 1237.31578947, and the remainder is 7e-09.
