394416 divided by 78 
Our goal is to divide 394416 by 78.

On to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 78

Step 2:
When dividing 39 by 78, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 78

Advancing to step 3:
If we divide 394 by 78, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 390 from 394 and we're left with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 78

Going ahead to step 4:
If we divide 44 by 78, we get 0 and a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 44, we end up with 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 78

Moving on to step 5:
78 goes into 441 5 times with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Subtracting 390 from 441 leaves us with 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 78

Step 6:
78 goes into 516 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 5056.0
Subtracting 468 from 516 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 5056.6
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 5056.61
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
78 goes into 420 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5056.615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 78, we get 3 and a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 5056.6153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
78 goes into 660 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 5056.61538
If we take 624 away from 660, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 5056.615384
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
If we divide 480 by 78, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 5056.6153846
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
If we divide 120 by 78, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 5056.61538461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 5056.61538461 with a remaining 4.2e-08.
