We look at the division of 390400 by 38 
Our goal is to divide 390400 by 38.

Let's proceed to step 1:
38 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 38

Moving on to step 2:
38 can be fit into 39 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 38 from 39 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 38

Step 3:
38 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 10, we end up with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 38

Step 4:
104 divided by 38 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 76 from 104, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 38

Let's proceed to step 5:
38 can be fit into 280 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 1027.0
If we take 266 away from 280, we end up with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 38

Advancing to step 6:
38 can be fit into 140 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 10273.0
If we subtract 114 from 140, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
When dividing 260 by 38, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 10273.6
Deduct 228 from 260 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10273.68
If we take 304 away from 320, we end up 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.

Advancing to step 9:
38 goes into 160 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10273.684
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.

Going ahead to step 10:
The number 38 fits into 80 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 10273.6842
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.

Let's proceed to step 11:
38 can be fit into 40 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 10273.68421
Subtracting 38 from 40 leaves us 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.

Going ahead to step 12:
38 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10273.68421
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
If we divide 200 by 38, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 10273.6842105
The remainder is 10 after subtracting 190 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
38 can be fit into 100 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 10273.68421052
Deduct 76 from 100 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 10273.68421052 and a remainder of 2.4e-08.
