We look at the division of 615664 by 13 
Our goal is to divide 615664 by 13.

On to 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
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 13

Moving on to step 2:
The number 13 fits into 61 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 52 from 61 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 13

Going ahead to step 3:
13 can be fit into 95 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 91 away from 95, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 13

Step 4:
When dividing 46 by 13, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 473.0
Subtracting 39 from 46 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 13

On to step 5:
13 can be fit into 76 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 4735.0
Subtract 65 from 76 to get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 13

On to step 6:
13 can be fit into 114 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 47358.0
If we subtract 104 from 114, 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.

On to step 7:
100 divided by 13 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 47358.7
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 8:
When dividing 90 by 13, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 47358.76
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.

Let's proceed to step 9:
120 divided by 13 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 47358.769
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.

Let's proceed to step 10:
13 can be fit into 30 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 47358.7692
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.

Moving on to step 11:
If we divide 40 by 13, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 47358.76923
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.

On to step 12:
13 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 47358.76923
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.

Let's proceed to step 13:
13 goes into 100 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 47358.7692307
Subtracting 91 from 100 leaves us 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.

On to step 14:
When dividing 90 by 13, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 47358.76923076
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.

The quotient of the division is 47358.76923076, and the remainder is 1.2e-08.
