Let's divide 285296 by 13
The aim is to understand the frequency of 13 in 285296.

On to step 1:
13 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 13

Step 2:
13 goes into 28 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 26 from 28 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 13

Advancing to step 3:
13 can be fit into 25 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 13 from 25 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 13

Moving on to step 4:
If we divide 122 by 13, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 219.0
The remainder is 5 after subtracting 117 from 122.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 13

Let's proceed to step 5:
The number 13 fits into 59 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 2194.0
Deduct 52 from 59 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 13

Let's proceed to step 6:
When dividing 76 by 13, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 21945.0
Deduct 65 from 76 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.

On to step 7:
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: 21945.8
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.

On to step 8:
If we divide 60 by 13, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 21945.84
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.

Step 9:
13 goes into 80 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 21945.846
If we take 78 away from 80, we end up 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.

Going ahead to step 10:
If we divide 20 by 13, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 21945.8461
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.

Step 11:
70 divided by 13 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21945.84615
Subtracting 65 from 70 leaves us 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 12:
13 goes into 50 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 21945.846153
Subtracting 39 from 50 leaves us 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.

Moving on to step 13:
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: 21945.8461538
Deduct 104 from 110 and we're left 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 14:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 21945.84615384
Subtract 52 from 60 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 21945.84615384 with a remaining 8e-09.
