We divide 65315950 by 13
The aim is to understand the frequency of 13 in 65315950.

Step 1:
When dividing 6 by 13, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 13

Let's proceed to step 2:
13 can be fit into 65 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 65 from 65 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 13

Let's proceed to step 3:
13 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 13

Moving on to step 4:
When dividing 31 by 13, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 502.0
Subtracting 26 from 31 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 13

Moving on to step 5:
The number 13 fits into 55 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 5024.0
Deduct 52 from 55 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 13

Step 6:
13 goes into 39 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 50243.0
Deduct 39 from 39 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 13

On to step 7:
13 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 502430.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 13

Moving on to step 8:
50 divided by 13 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 5024303.0
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.

Moving on to step 9:
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: 5024303.8
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
13 can be fit into 60 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 5024303.84
Subtracting 52 from 60 leaves us 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 11:
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: 5024303.846
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 5024303.8461
If we take 13 away from 20, we end up 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.

Going ahead to step 13:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5024303.84615
If we take 65 away from 70, we end up with 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 14:
13 goes into 50 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 5024303.846153
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.

Going ahead to step 15:
If we divide 110 by 13, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 5024303.8461538
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 16:
60 divided by 13 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5024303.84615384
Deduct 52 from 60 and we're left 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.

The final result is 5024303.84615384 with a remainder of 8e-09.
