Let's divide 393915 by 38
We're looking to find how many times 38 goes into 393915.

On to step 1:
38 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 38

Let's proceed to step 2:
When dividing 39 by 38, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 38 from 39 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 38

Step 3:
If we divide 13 by 38, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 38

Advancing to step 4:
The number 38 fits into 139 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we take 114 away from 139, we end up with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 38

Advancing to step 5:
38 goes into 251 6 times with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 1036.0
If we subtract 228 from 251, we get 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 38

Advancing to step 6:
38 can be fit into 235 6 times, resulting in a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 10366.0
If we take 228 away from 235, we end up 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.

Let's proceed to step 7:
38 goes into 70 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 10366.1
The remainder is 32 after subtracting 38 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
38 can be fit into 320 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 10366.18
Subtract 304 from 320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
The number 38 fits into 160 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 10366.184
The remainder is 8 after subtracting 152 from 160.
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:
80 divided by 38 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10366.1842
Subtracting 76 from 80 leaves us with 4.
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 11:
When dividing 40 by 38, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 10366.18421
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.

On to step 12:
38 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 10366.18421
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
The number 38 fits into 200 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 10366.1842105
Deduct 190 from 200 and we're left with 10.
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:
If we divide 100 by 38, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 10366.18421052
Subtract 76 from 100 to 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.

Our division results in 10366.18421052 with a remaining 2.4e-08.
