639353 divided by 13 
We want to figure out the number of times 639353 can be divided by 13.

Going ahead to step 1:
6 divided by 13 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 13

Step 2:
If we divide 63 by 13, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 52 from 63, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 13

On to step 3:
If we divide 119 by 13, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 117 away from 119, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 13

Step 4:
13 can be fit into 23 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 491.0
If we subtract 13 from 23, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 13

On to step 5:
105 divided by 13 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 4918.0
Deduct 104 from 105 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 13

Moving on to step 6:
13 can be fit into 13 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 49181.0
Subtracting 13 from 13 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
13 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 49181.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
13 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49181.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 49181.0, and the remainder is 0.0.
