247197 ÷ 78 
Our goal is to divide 247197 by 78.

Let's proceed to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 78

On to step 2:
78 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 78

Advancing to step 3:
The number 78 fits into 247 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 13 after subtracting 234 from 247.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 78

On to step 4:
When dividing 131 by 78, we get 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 78 away from 131, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 78

Let's proceed to step 5:
78 can be fit into 539 6 times, resulting in a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
If we subtract 468 from 539, we get 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 78

Step 6:
717 divided by 78 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 3169.0
The remainder is 15 after subtracting 702 from 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
150 divided by 78 is 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 3169.1
If we take 78 away from 150, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
If we divide 720 by 78, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 3169.19
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 3169.192
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 78, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3169.1923
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
78 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 3169.1923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
When dividing 600 by 78, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 3169.192307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
When dividing 540 by 78, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 3169.1923076
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 3169.19230769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 3169.19230769, with a leftover of 1.8e-08.
