We're dividing 489721 by 13 
We want to divide 489721 by 13.

Step 1:
If we divide 4 by 13, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 13

Step 2:
48 divided by 13 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 9 after subtracting 39 from 48.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 13

Step 3:
When dividing 99 by 13, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 8 after subtracting 91 from 99.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 13

Going ahead to step 4:
13 can be fit into 87 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 376.0
Subtract 78 from 87 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 13

Step 5:
The number 13 fits into 92 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 3767.0
Subtracting 91 from 92 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 13

Step 6:
If we divide 11 by 13, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 37670.0
The remainder is 11 after subtracting 0 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
The number 13 fits into 110 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 37670.8
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 13, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 37670.84
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.

Moving on to step 9:
When dividing 80 by 13, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 37670.846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
20 divided by 13 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 37670.8461
Subtracting 13 from 20 leaves us 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.

Advancing to step 11:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 37670.84615
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.

Advancing to step 12:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 37670.846153
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 13:
When dividing 110 by 13, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 37670.8461538
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 14:
13 goes into 60 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 37670.84615384
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.

After the division, we end up with 37670.84615384 and a remainder of 8e-09.
