Let's divide 129742 by 38
Our goal is to divide 129742 by 38.

Step 1:
When dividing 1 by 38, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 38

Let's proceed to step 2:
38 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 38

Let's proceed to step 3:
The number 38 fits into 129 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 114 away from 129, we end up with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 38

Let's proceed to step 4:
If we divide 157 by 38, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 152 away from 157, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 38

Going ahead to step 5:
When dividing 54 by 38, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 341.0
The remainder is 16 after subtracting 38 from 54.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 38

On to step 6:
38 goes into 162 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 3414.0
The remainder is 10 after subtracting 152 from 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
100 divided by 38 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3414.2
If we subtract 76 from 100, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
38 can be fit into 240 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3414.26
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
When dividing 120 by 38, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3414.263
Subtracting 114 from 120 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.

On to step 10:
60 divided by 38 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 3414.2631
The remainder is 22 after subtracting 38 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
When dividing 220 by 38, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 3414.26315
If we take 190 away from 220, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
When dividing 300 by 38, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 3414.263157
Subtracting 266 from 300 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
The number 38 fits into 340 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 3414.2631578
If we take 304 away from 340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
38 goes into 360 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 3414.26315789
If we subtract 342 from 360, we 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.

The final result is 3414.26315789 with a remainder of 1.8e-08.
