487621 divided by 13 
We want to figure out the number of times 487621 can be divided by 13.

Let's proceed to step 1:
13 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 13

Moving on to step 2:
When dividing 48 by 13, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 39 from 48, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 13

Moving on to step 3:
When dividing 97 by 13, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 91 from 97, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 13

Moving on to step 4:
When dividing 66 by 13, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 375.0
Subtract 65 from 66 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 13

Moving on to step 5:
When dividing 12 by 13, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 3750.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 13

Advancing to step 6:
13 goes into 121 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 37509.0
If we subtract 117 from 121, 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.

Advancing to step 7:
13 goes into 40 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 37509.3
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.

Let's proceed to step 8:
10 divided by 13 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 37509.3
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.

Moving on to step 9:
When dividing 100 by 13, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 37509.307
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.

Going ahead to step 10:
90 divided by 13 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 37509.3076
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.

Step 11:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 37509.30769
Subtracting 117 from 120 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.

On to step 12:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 37509.307692
Deduct 26 from 30 and we're left 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.

Going ahead to step 13:
13 can be fit into 40 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 37509.3076923
Subtract 39 from 40 to 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.

Step 14:
10 divided by 13 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 37509.3076923
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 37509.3076923 with a remainder of 1e-08.
