We divide 139100 by 13
The aim is to understand the frequency of 13 in 139100.

Let's proceed to step 1:
13 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 13

Moving on to step 2:
13 divided by 13 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 13 away from 13, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 13

Moving on to step 3:
13 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 13

Advancing to step 4:
The number 13 fits into 91 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 91 away from 91, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 13

Step 5:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1070.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 13

Moving on to step 6:
13 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10700.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 13 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10700.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
13 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10700.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10700.0, with a leftover of 0.0.
