239805 ÷ 19 
Our goal is to divide 239805 by 19.

On to step 1:
19 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 19

Step 2:
The number 19 fits into 23 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 19 away from 23, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 19

On to step 3:
49 divided by 19 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 38 from 49, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 19

Step 4:
If we divide 118 by 19, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 114 from 118 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 19

Step 5:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1262.0
The remainder is 2 after subtracting 38 from 40.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 19

Moving on to step 6:
25 divided by 19 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 12621.0
Subtracting 19 from 25 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 12621.3
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 12621.31
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
19 goes into 110 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12621.315
Subtracting 95 from 110 leaves us 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 10:
150 divided by 19 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 12621.3157
Deduct 133 from 150 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
170 divided by 19 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 12621.31578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
180 divided by 19 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 12621.315789
Subtracting 171 from 180 leaves us with 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 13:
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: 12621.3157894
Subtract 76 from 90 to 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 14:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 12621.31578947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 12621.31578947, with a leftover of 7e-09.
