503820 ÷ 13 
We want to divide 503820 by 13.

Moving on to step 1:
5 divided by 13 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 13

Going ahead to step 2:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 39 from 50, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 13

Going ahead to step 3:
13 goes into 113 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 104 away from 113, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 13

Advancing to step 4:
The number 13 fits into 98 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 387.0
Subtract 91 from 98 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 13

Advancing to step 5:
13 goes into 72 5 times with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 3875.0
If we take 65 away from 72, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 13

Advancing to step 6:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 38755.0
If we subtract 65 from 70, we 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.

Let's proceed to step 7:
If we divide 50 by 13, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 38755.3
If we take 39 away from 50, we end up 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.

Advancing to step 8:
The number 13 fits into 110 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 38755.38
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.

Moving on 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: 38755.384
Subtracting 52 from 60 leaves us 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.

Let's proceed to step 10:
13 goes into 80 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 38755.3846
If we subtract 78 from 80, we get 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 11:
13 can be fit into 20 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 38755.38461
Subtract 13 from 20 to 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.

On to step 12:
If we divide 70 by 13, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 38755.384615
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.

Step 13:
50 divided by 13 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 38755.3846153
If we take 39 away from 50, we end up 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.

Going ahead to step 14:
If we divide 110 by 13, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 38755.38461538
Deduct 104 from 110 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.

The final outcome is 38755.38461538, with a leftover of 6e-09.
