642515 divided by 13 
Let's see how many times 13 fits into 642515.

Let's proceed to step 1:
When dividing 6 by 13, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 13

Advancing to step 2:
13 goes into 64 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 52 from 64 to get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 13

Step 3:
If we divide 122 by 13, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 5 after subtracting 117 from 122.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 13

Let's proceed to step 4:
When dividing 55 by 13, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 494.0
Subtracting 52 from 55 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 13

On to step 5:
The number 13 fits into 31 2 times, leaving a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 4942.0
The remainder is 5 after subtracting 26 from 31.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 13

Moving on to step 6:
13 can be fit into 55 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 49424.0
If we subtract 52 from 55, 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 7:
When dividing 30 by 13, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 49424.2
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.

Moving on to step 8:
40 divided by 13 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 49424.23
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
13 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 49424.23
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.

Going ahead to step 10:
13 goes into 100 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 49424.2307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
The number 13 fits into 90 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 49424.23076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
When dividing 120 by 13, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 49424.230769
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.

Moving on to step 13:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 49424.2307692
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.

Let's proceed to step 14:
13 goes into 40 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 49424.23076923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 49424.23076923 with a remaining 1e-09.
