381057 ÷ 78 
Let's see how many times 78 fits into 381057.

Step 1:
The number 78 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 78

Step 2:
38 divided by 78 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 78

Let's proceed to step 3:
The number 78 fits into 381 4 times, leaving a remainder of 69.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 312 from 381, we get 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 78

Advancing to step 4:
When dividing 690 by 78, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 624 from 690, we get 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 78

Let's proceed to step 5:
When dividing 665 by 78, we get 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 488.0
If we subtract 624 from 665, we get 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 78

Advancing to step 6:
78 can be fit into 417 5 times, resulting in a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 4885.0
If we subtract 390 from 417, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
When dividing 270 by 78, we get 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 4885.3
If we take 234 away from 270, 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 8:
If we divide 360 by 78, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 4885.34
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
If we divide 480 by 78, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 4885.346
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 78 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 4885.3461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4885.34615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
300 divided by 78 is 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 4885.346153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
660 divided by 78 is 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 4885.3461538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 4885.34615384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 4885.34615384 with a remaining 4.8e-08.
