We look at the division of 394658 by 78 
We want to divide 394658 by 78.

Advancing to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 78

Let's proceed to step 2:
78 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
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

Moving on to step 3:
When dividing 394 by 78, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 390 from 394 to get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 78

Going ahead to step 4:
46 divided by 78 is 0 with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 46 after subtracting 0 from 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 78

Moving on to step 5:
If we divide 465 by 78, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 505.0
The remainder is 75 after subtracting 390 from 465.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 78

Moving on to step 6:
78 can be fit into 758 9 times, resulting in a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 5059.0
If we take 702 away from 758, we end up with 56.
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 7:
78 goes into 560 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 5059.7
If we take 546 away from 560, we end up 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 8:
78 goes into 140 1 times with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 5059.71
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 5059.717
If we subtract 546 from 620, we 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.

Let's proceed to step 10:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 5059.7179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
78 goes into 380 4 times with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 5059.71794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 5059.717948
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 5059.7179487
Subtracting 546 from 560 leaves us 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.

On to step 14:
140 divided by 78 is 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 5059.71794871
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 5059.71794871 with a remainder of 6.2e-08.
