Let's divide 664045 by 13
We're looking to find how many times 13 goes into 664045.

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
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 13

Advancing to step 2:
13 goes into 66 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 65 from 66 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 13

Moving on to step 3:
13 can be fit into 14 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 51.0
The remainder is 1 after subtracting 13 from 14.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 13

Moving on to step 4:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 510.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 13

Going ahead to step 5:
13 can be fit into 104 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 5108.0
The remainder is 0 after subtracting 104 from 104.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 13

Step 6:
When dividing 5 by 13, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 51080.0
If we subtract 0 from 5, 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 7:
50 divided by 13 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 51080.3
If we take 39 away from 50, we end up with 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:
When dividing 110 by 13, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 51080.38
If we take 104 away from 110, we end up 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.

Advancing to step 9:
13 goes into 60 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 51080.384
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 13 fits into 80 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 51080.3846
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.

Let's proceed to step 11:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 51080.38461
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.

Moving on to step 12:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 51080.384615
Subtract 65 from 70 to 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.

Going ahead to step 13:
If we divide 50 by 13, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 51080.3846153
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
110 divided by 13 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 51080.38461538
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.

The final outcome is 51080.38461538, with a leftover of 6e-09.
