1923390 ÷ 378 
We're looking to find how many times 378 goes into 1923390.

Let's proceed to step 1:
The number 378 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 378

Going ahead to step 2:
378 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 378

Moving on to step 3:
378 goes into 192 0 times with a remainder of 192.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 192 and we're left with 192.
Take the next digit (3) from the dividend and append it to 192, then repeat: 1923 / 378

Let's proceed to step 4:
378 goes into 1923 5 times with a remainder of 33.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 1890 from 1923 and we're left with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 378

Moving on to step 5:
333 divided by 378 is 0 with a remainder of 333.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 333 leaves us with 333.
Append the next digit (9) from the dividend to 333 and continue with: 3339 / 378

Moving on to step 6:
3339 divided by 378 is 8 with a remainder of 315.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
If we subtract 3024 from 3339, we get 315.
Take the next digit (0) from the dividend and append it to 315, then repeat: 3150 / 378

Step 7:
378 goes into 3150 8 times with a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 5088.0
If we subtract 3024 from 3150, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 8:
378 can be fit into 1260 3 times, resulting in a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 5088.3
Subtracting 1134 from 1260 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 9:
378 goes into 1260 3 times with a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 5088.33
The remainder is 126 after subtracting 1134 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Our division results in 5088.33 with a remaining 0.126.
