We divide 389950 by 78
Our goal is to divide 389950 by 78.

Let's proceed to step 1:
78 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 78

Going ahead to step 2:
38 divided by 78 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 78

Let's proceed to step 3:
When dividing 389 by 78, we get 4 with a remainder of 77.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 312 away from 389, we end up with 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 78

Step 4:
If we divide 779 by 78, we get 9 and a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtract 702 from 779 to get 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 78

Let's proceed to step 5:
The number 78 fits into 775 9 times, leaving a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 499.0
Subtracting 702 from 775 leaves us with 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 78

Moving on to step 6:
When dividing 730 by 78, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 4999.0
Subtracting 702 from 730 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 4999.3
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
78 can be fit into 460 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4999.35
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
When dividing 700 by 78, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 4999.358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 4999.3589
Subtracting 702 from 760 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
78 goes into 580 7 times with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4999.35897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 4999.358974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
When dividing 280 by 78, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 4999.3589743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
78 goes into 460 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 4999.35897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 4999.35897435 and a remainder of 7e-08.
