We're dividing 15241 by 78 
We want to divide 15241 by 78.

On to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 78

On to step 2:
15 divided by 78 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 78

Step 3:
78 can be fit into 152 1 times, resulting in a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 78 away from 152, we end up with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 78

Advancing to step 4:
744 divided by 78 is 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 702 from 744 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 78

On to step 5:
The number 78 fits into 421 5 times, leaving a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 195.0
If we subtract 390 from 421, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 6:
78 goes into 310 3 times with a remainder of 76.
The next digit of our result is 3. 
Result so far: 195.3
If we subtract 234 from 310, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 195.39
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.

Moving on to step 8:
If we divide 580 by 78, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 195.397
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
When dividing 340 by 78, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 195.3974
If we take 312 away from 340, we end up 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 10:
280 divided by 78 is 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 195.39743
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.

Going ahead to step 11:
If we divide 460 by 78, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 195.397435
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.

Let's proceed to step 12:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The next digit of our result is 8. 
Result so far: 195.3974358
The remainder is 76 after subtracting 624 from 700.
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 13:
78 goes into 760 9 times with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 195.39743589
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.

After the division, we end up with 195.39743589 and a remainder of 5.8e-08.
