We look at the division of 380429 by 78 
Our goal is to divide 380429 by 78.

On to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 78

Let's proceed to step 2:
78 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 78

Moving on to step 3:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 68 after subtracting 312 from 380.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 78

Going ahead to step 4:
If we divide 684 by 78, we get 8 and a remainder of 60.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 624 from 684 to get 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 78

Moving on to step 5:
78 can be fit into 602 7 times, resulting in a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 487.0
The remainder is 56 after subtracting 546 from 602.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 78

Step 6:
If we divide 569 by 78, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 4877.0
Subtract 546 from 569 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
When dividing 230 by 78, we get 2 with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 4877.2
Subtracting 156 from 230 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
If we divide 740 by 78, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 4877.29
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
380 divided by 78 is 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 4877.294
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
78 goes into 680 8 times with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 4877.2948
If we take 624 away from 680, 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.

Moving on to step 11:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4877.29487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
If we divide 140 by 78, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 4877.294871
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.

Step 13:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 4877.2948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
78 goes into 740 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 4877.29487179
Deduct 702 from 740 and we're left 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.

The final result is 4877.29487179 with a remainder of 3.8e-08.
