Let's divide 338487 by 78
We want to figure out the number of times 338487 can be divided by 78.

Going ahead to step 1:
3 divided by 78 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 78

Going ahead to step 2:
78 goes into 33 0 times with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 78

Going ahead to step 3:
78 can be fit into 338 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 312 away from 338, we end up with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 78

Going ahead to step 4:
264 divided by 78 is 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 30 after subtracting 234 from 264.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 78

On to step 5:
308 divided by 78 is 3 with a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 433.0
Deduct 234 from 308 and we're left with 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 78

On to step 6:
If we divide 747 by 78, we get 9 and a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 4339.0
If we take 702 away from 747, we end up 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.

Advancing to step 7:
450 divided by 78 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 4339.5
If we take 390 away from 450, 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 8:
When dividing 600 by 78, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 4339.57
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.

On to step 9:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 4339.576
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
If we divide 720 by 78, we get 9 and a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 4339.5769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 4339.57692
Subtracting 156 from 180 leaves us 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.

Let's proceed to step 12:
78 goes into 240 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 4339.576923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 4339.576923
Subtracting 0 from 60 leaves us 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.

Going ahead to step 14:
The number 78 fits into 600 7 times, leaving a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 4339.57692307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 4339.57692307 with a balance of 5.4e-08.
