Let's divide 665116 by 13
The aim is to understand the frequency of 13 in 665116.

Let's proceed to step 1:
6 divided by 13 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 13

On to step 2:
The number 13 fits into 66 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 65 away from 66, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 13

Let's proceed to step 3:
When dividing 15 by 13, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 13 from 15, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 13

Advancing to step 4:
13 goes into 21 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 511.0
The remainder is 8 after subtracting 13 from 21.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 13

Let's proceed to step 5:
The number 13 fits into 81 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 5116.0
Subtracting 78 from 81 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 13

Advancing to step 6:
36 divided by 13 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 51162.0
Subtract 26 from 36 to 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.

Advancing to step 7:
When dividing 100 by 13, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 51162.7
Deduct 91 from 100 and we're left 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 8:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 51162.76
Subtracting 78 from 90 leaves us 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 9:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 51162.769
Subtract 117 from 120 to get 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:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 51162.7692
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.

Step 11:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 51162.76923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
10 divided by 13 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 51162.76923
If we take 0 away from 10, we end up 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.

Moving on to step 13:
If we divide 100 by 13, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 51162.7692307
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
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: 51162.76923076
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 51162.76923076, and the remainder is 1.2e-08.
