380455 ÷ 78 
Let's see how many times 78 fits into 380455.

Going ahead to step 1:
The number 78 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 78

Let's proceed to step 2:
If we divide 38 by 78, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 78

Let's proceed to step 3:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 68 after subtracting 312 from 380.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 78

Step 4:
78 can be fit into 684 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 624 from 684 leaves us with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 78

Advancing to step 5:
78 goes into 605 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Subtract 546 from 605 to get 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 78

Advancing to step 6:
If we divide 595 by 78, we get 7 and a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 4877.0
If we take 546 away from 595, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
If we divide 490 by 78, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 4877.6
The remainder is 22 after subtracting 468 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 4877.62
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 4877.628
Subtract 624 from 640 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.

Let's proceed to step 10:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 4877.6282
If we take 156 away from 160, we end up 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.

Moving on to step 11:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4877.6282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 4877.628205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
If we divide 100 by 78, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 4877.6282051
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 4877.62820512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 4877.62820512 with a remaining 6.4e-08.
