43440 divided by 19 
Our goal is to divide 43440 by 19.

Let's proceed to step 1:
If we divide 4 by 19, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 19

Moving on to step 2:
If we divide 43 by 19, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 5 after subtracting 38 from 43.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 19

Advancing to step 3:
The number 19 fits into 54 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 16 after subtracting 38 from 54.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 19

Let's proceed to step 4:
19 goes into 164 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 228.0
If we subtract 152 from 164, we get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 19

Moving on to step 5:
When dividing 120 by 19, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 2286.0
Subtract 114 from 120 to 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.

Step 6:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 2286.3
Deduct 57 from 60 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.

Let's proceed to step 7:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 2286.31
Deduct 19 from 30 and we're left with 11.
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:
When dividing 110 by 19, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2286.315
Deduct 95 from 110 and we're left 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.

Advancing to step 9:
150 divided by 19 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 2286.3157
If we take 133 away from 150, we end up 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 10:
19 can be fit into 170 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 2286.31578
If we take 152 away from 170, we end up 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.

Step 11:
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: 2286.315789
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.

Moving on to step 12:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 2286.3157894
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.

Going ahead to step 13:
If we divide 140 by 19, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 2286.31578947
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 result is 2286.31578947 with a remainder of 7e-09.
