Let's divide 438623 by 13
We want to figure out the number of times 438623 can be divided by 13.

Going ahead to step 1:
When dividing 4 by 13, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 13

Step 2:
When dividing 43 by 13, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we take 39 away from 43, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 13

Step 3:
13 can be fit into 48 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 39 from 48 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 13

Let's proceed to step 4:
13 can be fit into 96 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 337.0
Subtract 91 from 96 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 13

On to step 5:
52 divided by 13 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 3374.0
The remainder is 0 after subtracting 52 from 52.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 13

Moving on to step 6:
13 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 33740.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
13 goes into 30 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 33740.2
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 33740.23
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 33740.23
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 33740.2307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
When dividing 90 by 13, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 33740.23076
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
If we divide 120 by 13, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 33740.230769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 33740.2307692
If we take 26 away from 30, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
If we divide 40 by 13, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 33740.23076923
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 33740.23076923, and the remainder is 1e-09.
