We're dividing 12378017 by 273 
We're looking to find how many times 273 goes into 12378017.

Moving on to step 1:
273 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 273

Moving on to step 2:
273 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 273

On to step 3:
The number 273 fits into 123 0 times, leaving a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 123 leaves us with 123.
Append the next digit (7) from the dividend to 123 and continue with: 1237 / 273

Let's proceed to step 4:
When dividing 1237 by 273, we get 4 with a remainder of 145.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1092 from 1237, we get 145.
Bring next digit (8) of the dividend behind the 145 and repeat the process: 1458 / 273

Advancing to step 5:
1458 divided by 273 is 5 with a remainder of 93.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 1365 from 1458 leaves us with 93.
Append the next digit (0) from the dividend to 93 and continue with: 930 / 273

Advancing to step 6:
273 goes into 930 3 times with a remainder of 111.
The next digit of our result is 3. 
Result so far: 453.0
If we subtract 819 from 930, we get 111.
Take the next digit (1) from the dividend and append it to 111, then repeat: 1111 / 273

Moving on to step 7:
273 can be fit into 1111 4 times, resulting in a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 4534.0
If we subtract 1092 from 1111, we get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 273

Advancing to step 8:
If we divide 197 by 273, we get 0 and a remainder of 197.
Record the quotient 0 as the next digit in the result. 
Result so far: 45340.0
The remainder is 197 after subtracting 0 from 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 9:
273 goes into 1970 7 times with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 45340.7
The remainder is 59 after subtracting 1911 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 10:
When dividing 590 by 273, we get 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 45340.72
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
440 divided by 273 is 1 with a remainder of 167.
Write down 1 as next digit of the result. 
Result so far: 45340.721
If we subtract 273 from 440, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 12:
The number 273 fits into 1670 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 45340.7216
If we subtract 1638 from 1670, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
320 divided by 273 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 45340.72161
Subtract 273 from 320 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 14:
273 can be fit into 470 1 times, resulting in a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 45340.721611
Subtracting 273 from 470 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

In conclusion, the division gives 45340.721611 with a balance of 1.97e-05.
