Let's divide 387392 by 78
We want to figure out the number of times 387392 can be divided by 78.

Let's proceed to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 78

Moving on to step 2:
The number 78 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 78

Step 3:
If we divide 387 by 78, we get 4 and a remainder of 75.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 312 from 387 and we're left with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 78

Moving on to step 4:
If we divide 753 by 78, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 702 away from 753, we end up with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 78

Step 5:
The number 78 fits into 519 6 times, leaving a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 496.0
Deduct 468 from 519 and we're left with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 78

Let's proceed to step 6:
78 can be fit into 512 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 4966.0
Subtracting 468 from 512 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 78, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4966.5
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4966.56
Subtracting 468 from 500 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.

Step 9:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4966.564
Deduct 312 from 320 and we're left 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.

On to step 10:
The number 78 fits into 80 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 4966.5641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
If we divide 20 by 78, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4966.5641
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 4966.564102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
The number 78 fits into 440 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 4966.5641025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
If we divide 500 by 78, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 4966.56410256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 4966.56410256 with a remainder of 3.2e-08.
