We look at the division of 128439 by 38 
Let's see how many times 38 fits into 128439.

On to step 1:
The number 38 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 38

Let's proceed to step 2:
The number 38 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 38

Let's proceed to step 3:
When dividing 128 by 38, we get 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 114 from 128 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 38

Going ahead to step 4:
38 can be fit into 144 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 33.0
If we take 114 away from 144, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 38

On to step 5:
38 goes into 303 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 337.0
If we subtract 266 from 303, we get 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 38

Going ahead to step 6:
38 goes into 379 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 3379.0
The remainder is 37 after subtracting 342 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
When dividing 370 by 38, we get 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 3379.9
Deduct 342 from 370 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
280 divided by 38 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 3379.97
Subtracting 266 from 280 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.

On to step 9:
140 divided by 38 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 3379.973
The remainder is 26 after subtracting 114 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 3379.9736
If we subtract 228 from 260, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
38 can be fit into 320 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3379.97368
Deduct 304 from 320 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 38, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3379.973684
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 38 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 3379.9736842
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
When dividing 40 by 38, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 3379.97368421
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 3379.97368421 with a remainder of 2e-09.
