278904 divided by 13 
Our goal is to divide 278904 by 13.

Going ahead to step 1:
If we divide 2 by 13, 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.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 13

Moving on to step 2:
27 divided by 13 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 26 from 27 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 13

Advancing to step 3:
When dividing 18 by 13, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 13 from 18 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 13

Advancing to step 4:
The number 13 fits into 59 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 214.0
If we subtract 52 from 59, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 13

Let's proceed to step 5:
When dividing 70 by 13, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2145.0
Subtract 65 from 70 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 13

Moving on to step 6:
When dividing 54 by 13, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 21454.0
If we take 52 away from 54, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 13, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 21454.1
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
13 goes into 70 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21454.15
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 21454.153
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
When dividing 110 by 13, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 21454.1538
If we take 104 away from 110, we end up 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.

Going ahead to step 11:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 21454.15384
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 13, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 21454.153846
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 21454.1538461
If we take 13 away from 20, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
If we divide 70 by 13, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 21454.15384615
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 21454.15384615 with a remainder of 5e-09.
