We're dividing 543430 by 19 
We want to figure out the number of times 543430 can be divided by 19.

On to step 1:
The number 19 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 19

Let's proceed to step 2:
When dividing 54 by 19, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 16 after subtracting 38 from 54.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 19

Step 3:
19 can be fit into 163 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 152 from 163 to get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 19

Going ahead to step 4:
When dividing 114 by 19, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 286.0
Subtract 114 from 114 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 19

Step 5:
19 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 2860.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 19

On to step 6:
If we divide 30 by 19, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 28601.0
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.

On to step 7:
110 divided by 19 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 28601.5
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
19 goes into 150 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 28601.57
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.

Going ahead to step 9:
170 divided by 19 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 28601.578
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.

On to step 10:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 28601.5789
The remainder is 9 after subtracting 171 from 180.
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 11:
When dividing 90 by 19, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 28601.57894
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.

Step 12:
The number 19 fits into 140 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 28601.578947
Deduct 133 from 140 and we're left 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.

Moving on to step 13:
19 can be fit into 70 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 28601.5789473
Subtracting 57 from 70 leaves us 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.

On to step 14:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 28601.57894736
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 28601.57894736 and a remainder of 1.6e-08.
