390445 ÷ 38 
Our goal is to divide 390445 by 38.

Advancing to step 1:
38 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 38

On to step 2:
When dividing 39 by 38, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 38 from 39, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 38

Going ahead to step 3:
When dividing 10 by 38, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 38

Moving on to step 4:
The number 38 fits into 104 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we subtract 76 from 104, we get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 38

Advancing to step 5:
284 divided by 38 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 1027.0
Deduct 266 from 284 and we're left with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 38

Advancing to step 6:
When dividing 185 by 38, we get 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 10274.0
Subtracting 152 from 185 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
When dividing 330 by 38, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 10274.8
Deduct 304 from 330 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
38 goes into 260 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 10274.86
Subtracting 228 from 260 leaves us 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.

Moving on to step 9:
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: 10274.868
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.

Advancing to step 10:
38 can be fit into 160 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 10274.8684
Subtracting 152 from 160 leaves us 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 11:
The number 38 fits into 80 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10274.86842
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 12:
If we divide 40 by 38, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 10274.868421
If we subtract 38 from 40, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
20 divided by 38 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10274.868421
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
When dividing 200 by 38, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 10274.86842105
If we take 190 away from 200, we end up 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.

The final outcome is 10274.86842105, with a leftover of 1e-08.
