812856 ÷ 13 
The aim is to understand the frequency of 13 in 812856.

Going ahead to step 1:
The number 13 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 13

Going ahead to step 2:
The number 13 fits into 81 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 78 from 81 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 13

Step 3:
13 can be fit into 32 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 26 from 32 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 13

On to step 4:
When dividing 68 by 13, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 625.0
Subtract 65 from 68 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 13

Let's proceed to step 5:
If we divide 35 by 13, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 6252.0
The remainder is 9 after subtracting 26 from 35.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 13

Advancing to step 6:
If we divide 96 by 13, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 62527.0
If we subtract 91 from 96, we 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.

Advancing to step 7:
13 goes into 50 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 62527.3
If we take 39 away from 50, we end up 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.

Advancing to step 8:
If we divide 110 by 13, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 62527.38
Subtracting 104 from 110 leaves us 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 9:
13 goes into 60 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 62527.384
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.

Advancing to step 10:
13 goes into 80 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 62527.3846
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.

Going ahead to step 11:
13 goes into 20 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 62527.38461
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.

Step 12:
When dividing 70 by 13, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 62527.384615
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 13:
If we divide 50 by 13, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 62527.3846153
If we take 39 away from 50, we end up 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.

Step 14:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 62527.38461538
Subtract 104 from 110 to 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.

In conclusion, the division gives 62527.38461538 with a balance of 6e-09.
