Let's divide 641390 by 13
Let's see how many times 13 fits into 641390.

Moving on to step 1:
If we divide 6 by 13, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 13

On to step 2:
13 goes into 64 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 52 from 64, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 13

Let's proceed to step 3:
13 can be fit into 121 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 4 after subtracting 117 from 121.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 13

Let's proceed to step 4:
43 divided by 13 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 493.0
Deduct 39 from 43 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 13

Advancing to step 5:
49 divided by 13 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 4933.0
The remainder is 10 after subtracting 39 from 49.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 13

Let's proceed to step 6:
13 goes into 100 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 49337.0
If we take 91 away from 100, we end up 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 7:
When dividing 90 by 13, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 49337.6
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.

Going ahead to step 8:
When dividing 120 by 13, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 49337.69
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 13 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 49337.692
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.

Advancing to step 10:
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: 49337.6923
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 11:
13 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 49337.6923
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
When dividing 100 by 13, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 49337.692307
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
When dividing 90 by 13, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 49337.6923076
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 14:
13 goes into 120 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 49337.69230769
If we take 117 away from 120, we end up 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.

In conclusion, the division gives 49337.69230769 with a balance of 3e-09.
