We divide 134783 by 13
The aim is to understand the frequency of 13 in 134783.

Step 1:
If we divide 1 by 13, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 13

Step 2:
13 can be fit into 13 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 13 from 13 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 13

On to step 3:
13 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 13

Let's proceed to step 4:
13 can be fit into 47 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we subtract 39 from 47, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 13

Advancing to step 5:
The number 13 fits into 88 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 1036.0
The remainder is 10 after subtracting 78 from 88.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 13

Advancing to step 6:
When dividing 103 by 13, we get 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 10367.0
Deduct 91 from 103 and we're left 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.

Advancing to step 7:
When dividing 120 by 13, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 10367.9
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.

On to step 8:
When dividing 30 by 13, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10367.92
Deduct 26 from 30 and we're left 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 9:
40 divided by 13 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 10367.923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10367.923
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
When dividing 100 by 13, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 10367.92307
If we take 91 away from 100, we end up 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.

Going ahead to step 12:
If we divide 90 by 13, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10367.923076
If we subtract 78 from 90, we get 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 13:
When dividing 120 by 13, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 10367.9230769
If we take 117 away from 120, we end up 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 14:
If we divide 30 by 13, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10367.92307692
If we take 26 away from 30, 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.

The final outcome is 10367.92307692, with a leftover of 4e-09.
