Let's divide 387018 by 78
We want to figure out the number of times 387018 can be divided by 78.

On to step 1:
3 divided by 78 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 78

Moving on to step 2:
The number 78 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 78

On to step 3:
78 can be fit into 387 4 times, resulting in a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 312 from 387 to get 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 78

Step 4:
78 can be fit into 750 9 times, resulting in a remainder of 48.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 702 from 750 and we're left with 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 78

On to step 5:
If we divide 481 by 78, we get 6 and a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 496.0
Subtracting 468 from 481 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 78

Step 6:
If we divide 138 by 78, we get 1 and a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 4961.0
If we subtract 78 from 138, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 4961.7
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
When dividing 540 by 78, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 4961.76
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 4961.769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 4961.7692
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 4961.76923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4961.76923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
600 divided by 78 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 4961.7692307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
540 divided by 78 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 4961.76923076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 4961.76923076 with a remaining 7.2e-08.
