378344 divided by 77 
We want to divide 378344 by 77.

Moving on to step 1:
The number 77 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
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 77

Let's proceed to step 2:
77 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 77

On to step 3:
378 divided by 77 is 4 with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 308 away from 378, we end up with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 77

Advancing to step 4:
77 can be fit into 703 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 693 from 703 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 77

Step 5:
The number 77 fits into 104 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 491.0
If we subtract 77 from 104, we get 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 77

Step 6:
274 divided by 77 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 4913.0
Deduct 231 from 274 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
77 can be fit into 430 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 4913.5
Subtracting 385 from 430 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
The number 77 fits into 450 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 4913.55
Subtract 385 from 450 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 4913.55 and a remainder of 0.065.
