641796 ÷ 13 
Let's see how many times 13 fits into 641796.

Step 1:
6 divided by 13 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 13

Let's proceed to step 2:
The number 13 fits into 64 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 52 away from 64, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 13

On to step 3:
121 divided by 13 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 4 after subtracting 117 from 121.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 13

On to step 4:
The number 13 fits into 47 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
If we subtract 39 from 47, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 13

Let's proceed to step 5:
The number 13 fits into 89 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 4936.0
The remainder is 11 after subtracting 78 from 89.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 13

Going ahead to step 6:
13 can be fit into 116 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 49368.0
The remainder is 12 after subtracting 104 from 116.
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 7:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 49368.9
Deduct 117 from 120 and we're left 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 8:
The number 13 fits into 30 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 49368.92
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 49368.923
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.

Advancing to step 10:
13 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 49368.923
Subtracting 0 from 10 leaves us 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 11:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 49368.92307
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.

Step 12:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 49368.923076
If we take 78 away from 90, we end up with 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 13:
120 divided by 13 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 49368.9230769
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.

Going ahead to step 14:
The number 13 fits into 30 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 49368.92307692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 49368.92307692, with a leftover of 4e-09.
