Let's divide 388307 by 78
We want to divide 388307 by 78.

On to step 1:
78 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 78

Let's proceed to step 2:
78 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 78

Going ahead to step 3:
78 can be fit into 388 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 312 from 388 to get 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 78

Going ahead to step 4:
763 divided by 78 is 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 702 from 763, we get 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 78

Let's proceed to step 5:
78 can be fit into 610 7 times, resulting in a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 497.0
If we take 546 away from 610, we end up with 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 78

Let's proceed to step 6:
78 goes into 647 8 times with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 4978.0
Subtract 624 from 647 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
If we divide 230 by 78, we get 2 and a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 4978.2
Deduct 156 from 230 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
78 goes into 740 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 4978.29
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
If we divide 380 by 78, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4978.294
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 4978.2948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
The number 78 fits into 560 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 4978.29487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 4978.294871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
When dividing 620 by 78, we get 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 4978.2948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
740 divided by 78 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4978.29487179
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 4978.29487179 and a remainder of 3.8e-08.
