We're dividing 366815 by 78 
We're looking to find how many times 78 goes into 366815.

Let's proceed to step 1:
78 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 78

Moving on to step 2:
If we divide 36 by 78, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 78

Going ahead to step 3:
If we divide 366 by 78, we get 4 and a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 312 from 366 to get 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 78

Step 4:
When dividing 548 by 78, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 47.0
Deduct 546 from 548 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 78

Advancing to step 5:
78 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 470.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 78

Moving on to step 6:
215 divided by 78 is 2 with a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 4702.0
The remainder is 59 after subtracting 156 from 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
78 goes into 590 7 times with a remainder of 44.
The next digit of our result is 7. 
Result so far: 4702.7
Subtracting 546 from 590 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.

Moving on to step 8:
78 can be fit into 440 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4702.75
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
500 divided by 78 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 4702.756
If we take 468 away from 500, we end up 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.

Moving on to step 10:
78 goes into 320 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4702.7564
Subtracting 312 from 320 leaves us 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.

Let's proceed to step 11:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4702.75641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
If we divide 20 by 78, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4702.75641
The remainder is 20 after subtracting 0 from 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 13:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 4702.7564102
If we take 156 away from 200, we end up 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.

Moving on to step 14:
The number 78 fits into 440 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 4702.75641025
Deduct 390 from 440 and we're left 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.

Our division results in 4702.75641025 with a remaining 5e-08.
