663434 divided by 13 
We want to figure out the number of times 663434 can be divided by 13.

Let's proceed to step 1:
13 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 13

Moving on to step 2:
66 divided by 13 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 1 after subtracting 65 from 66.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 13

Moving on to step 3:
When dividing 13 by 13, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtract 13 from 13 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 13

Moving on to step 4:
When dividing 4 by 13, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 510.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 13

Moving on to step 5:
43 divided by 13 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 5103.0
Deduct 39 from 43 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 13

Going ahead to step 6:
13 can be fit into 44 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 51033.0
The remainder is 5 after subtracting 39 from 44.
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 7:
50 divided by 13 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 51033.3
If we subtract 39 from 50, we 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.

Advancing to step 8:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 51033.38
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 51033.384
Subtract 52 from 60 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 13 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 51033.3846
Subtract 78 from 80 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.

On to step 11:
When dividing 20 by 13, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 51033.38461
Deduct 13 from 20 and we're left 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.

On to step 12:
13 goes into 70 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 51033.384615
If we subtract 65 from 70, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 51033.3846153
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.

Advancing to step 14:
When dividing 110 by 13, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 51033.38461538
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.

After the division, we end up with 51033.38461538 and a remainder of 6e-09.
