We divide 303997 by 13
Let's see how many times 13 fits into 303997.

Step 1:
When dividing 3 by 13, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 13

Advancing to step 2:
13 can be fit into 30 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 26 from 30, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 13

Moving on to step 3:
When dividing 43 by 13, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 39 away from 43, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 13

Step 4:
13 can be fit into 49 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 233.0
Subtract 39 from 49 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 13

Let's proceed to step 5:
If we divide 109 by 13, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 2338.0
Subtract 104 from 109 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 13

On to step 6:
The number 13 fits into 57 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 23384.0
Subtract 52 from 57 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
13 goes into 50 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 23384.3
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 23384.38
Subtracting 104 from 110 leaves us 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.

Advancing to step 9:
When dividing 60 by 13, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 23384.384
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.

On to step 10:
If we divide 80 by 13, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 23384.3846
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.

Moving on to step 11:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 23384.38461
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.

Step 12:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 23384.384615
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.

Moving on to step 13:
13 goes into 50 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 23384.3846153
Subtracting 39 from 50 leaves us 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 14:
If we divide 110 by 13, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 23384.38461538
Subtracting 104 from 110 leaves us 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.

The quotient of the division is 23384.38461538, and the remainder is 6e-09.
