485721 ÷ 13 
We're looking to find how many times 13 goes into 485721.

Advancing to step 1:
The number 13 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 13

Going ahead to step 2:
13 can be fit into 48 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 39 from 48 leaves us with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 13

Let's proceed to step 3:
When dividing 95 by 13, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 91 from 95 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 13

On to step 4:
When dividing 47 by 13, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 373.0
If we subtract 39 from 47, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 13

Moving on to step 5:
If we divide 82 by 13, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3736.0
If we take 78 away from 82, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 13

Let's proceed to step 6:
If we divide 41 by 13, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 37363.0
Subtract 39 from 41 to 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.

Step 7:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 37363.1
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.

Going ahead to step 8:
13 goes into 70 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 37363.15
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.

Let's proceed to step 9:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 37363.153
Subtract 39 from 50 to get 11.
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 10:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 37363.1538
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.

Step 11:
If we divide 60 by 13, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 37363.15384
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.

Advancing to step 12:
If we divide 80 by 13, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 37363.153846
Subtracting 78 from 80 leaves us 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.

On to step 13:
20 divided by 13 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 37363.1538461
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.

On to step 14:
70 divided by 13 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 37363.15384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 37363.15384615 with a remaining 5e-09.
