We're dividing 26423038 by 13 
The aim is to understand the frequency of 13 in 26423038.

On to step 1:
2 divided by 13 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 13

Let's proceed to step 2:
If we divide 26 by 13, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 26 from 26 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 13

Step 3:
If we divide 4 by 13, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 13

Moving on to step 4:
If we divide 42 by 13, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
If we take 39 away from 42, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 13

Step 5:
13 can be fit into 33 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2032.0
Subtract 26 from 33 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 13

Going ahead to step 6:
If we divide 70 by 13, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 20325.0
Subtracting 65 from 70 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 13

Going ahead to step 7:
If we divide 53 by 13, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 203254.0
Deduct 52 from 53 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 13

On to step 8:
13 can be fit into 18 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 2032541.0
If we subtract 13 from 18, 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.

Step 9:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 2032541.3
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
13 goes into 110 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 2032541.38
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2032541.384
If we subtract 52 from 60, we 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.

Let's proceed to step 12:
When dividing 80 by 13, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2032541.3846
Deduct 78 from 80 and we're left 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.

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: 2032541.38461
Deduct 13 from 20 and we're left 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 14:
When dividing 70 by 13, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2032541.384615
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.

On to step 15:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 2032541.3846153
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.

Step 16:
110 divided by 13 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2032541.38461538
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.

After the division, we end up with 2032541.38461538 and a remainder of 6e-09.
