We're dividing 893637 by 13 
The aim is to understand the frequency of 13 in 893637.

Moving on 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
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 13

Step 2:
When dividing 89 by 13, we get 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 78 from 89 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 13

Step 3:
The number 13 fits into 113 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtract 104 from 113 to get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 13

Moving on to step 4:
When dividing 96 by 13, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
Subtract 91 from 96 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 13

Let's proceed to step 5:
53 divided by 13 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 6874.0
The remainder is 1 after subtracting 52 from 53.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 13

On to step 6:
When dividing 17 by 13, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 68741.0
If we take 13 away from 17, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 68741.3
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 68741.3
Subtracting 0 from 10 leaves us 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.

Going ahead to step 9:
When dividing 100 by 13, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 68741.307
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.

Let's proceed to step 10:
90 divided by 13 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 68741.3076
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.

Moving on to step 11:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 68741.30769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
If we divide 30 by 13, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 68741.307692
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 68741.3076923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 68741.3076923
If we subtract 0 from 10, we 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.

The quotient of the division is 68741.3076923, and the remainder is 1e-08.
