We divide 300431 by 19
We want to divide 300431 by 19.

Moving on to step 1:
3 divided by 19 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 19

Step 2:
30 divided by 19 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 19 away from 30, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 19

Let's proceed to step 3:
110 divided by 19 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 15 after subtracting 95 from 110.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 19

Step 4:
154 divided by 19 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we take 152 away from 154, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 19

Advancing to step 5:
23 divided by 19 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1581.0
Subtracting 19 from 23 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 19

Moving on to step 6:
41 divided by 19 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 15812.0
Deduct 38 from 41 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
19 goes into 30 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 15812.1
Subtract 19 from 30 to 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.

Moving on to step 8:
110 divided by 19 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15812.15
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.

Going ahead to step 9:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 15812.157
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:
19 can be fit into 170 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 15812.1578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
180 divided by 19 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 15812.15789
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.

Advancing to step 12:
19 goes into 90 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 15812.157894
Subtracting 76 from 90 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 15812.1578947
If we take 133 away from 140, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
When dividing 70 by 19, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 15812.15789473
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 15812.15789473 with a balance of 1.3e-08.
