We're dividing 551895 by 13 
The aim is to understand the frequency of 13 in 551895.

Advancing to step 1:
When dividing 5 by 13, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 13

Advancing to step 2:
13 can be fit into 55 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 52 from 55 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 13

Let's proceed to step 3:
The number 13 fits into 31 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we take 26 away from 31, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 13

Advancing to step 4:
13 can be fit into 58 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 424.0
Subtract 52 from 58 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 13

Step 5:
13 can be fit into 69 5 times, resulting in a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 4245.0
Subtract 65 from 69 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 13

Moving on to step 6:
If we divide 45 by 13, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 42453.0
If we subtract 39 from 45, we 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.

Let's proceed to step 7:
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: 42453.4
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.

Moving on to step 8:
13 goes into 80 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 42453.46
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 42453.461
Subtracting 13 from 20 leaves us 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 10:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 42453.4615
Deduct 65 from 70 and we're left 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.

Let's proceed to step 11:
13 goes into 50 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 42453.46153
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.

Let's proceed to step 12:
When dividing 110 by 13, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 42453.461538
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.

Step 13:
If we divide 60 by 13, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 42453.4615384
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.

On to step 14:
If we divide 80 by 13, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 42453.46153846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 42453.46153846, and the remainder is 2e-09.
