We're dividing 876293 by 13 
The aim is to understand the frequency of 13 in 876293.

Moving on to step 1:
The number 13 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 13

Step 2:
13 goes into 87 6 times with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 78 from 87 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 13

On to step 3:
13 goes into 96 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 67.0
Subtract 91 from 96 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 13

On to step 4:
The number 13 fits into 52 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 674.0
If we subtract 52 from 52, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 13

Going ahead to step 5:
13 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 6740.0
If we subtract 0 from 9, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 13

Moving on to step 6:
93 divided by 13 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 67407.0
Subtracting 91 from 93 leaves us 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.

Moving on to step 7:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 67407.1
Subtract 13 from 20 to get 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 8:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 67407.15
The remainder is 5 after subtracting 65 from 70.
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 9:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 67407.153
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 10:
13 goes into 110 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 67407.1538
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.

Let's proceed to step 11:
When dividing 60 by 13, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 67407.15384
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 12:
13 goes into 80 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 67407.153846
If we subtract 78 from 80, we 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.

On to step 13:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 67407.1538461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 67407.15384615
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.

After the division, we end up with 67407.15384615 and a remainder of 5e-09.
