We look at the division of 18055369 by 139 
The aim is to understand the frequency of 139 in 18055369.

Let's proceed to step 1:
139 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 139

Step 2:
The number 139 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 139

Moving on to step 3:
139 can be fit into 180 1 times, resulting in a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 139 from 180 leaves us with 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 139

Let's proceed to step 4:
415 divided by 139 is 2 with a remainder of 137.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 278 from 415, we get 137.
Include the next digit (5) from the dividend after 137, then repeat: 1375 / 139

On to step 5:
When dividing 1375 by 139, we get 9 with a remainder of 124.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 1251 away from 1375, we end up with 124.
Bring next digit (3) of the dividend behind the 124 and repeat the process: 1243 / 139

Moving on to step 6:
The number 139 fits into 1243 8 times, leaving a remainder of 131.
Put 8 as the next digit of the answer. 
Result so far: 1298.0
Subtracting 1112 from 1243 leaves us with 131.
Include the next digit (6) from the dividend after 131, then repeat: 1316 / 139

Advancing to step 7:
139 goes into 1316 9 times with a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 12989.0
Subtract 1251 from 1316 to get 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 139

Step 8:
When dividing 659 by 139, we get 4 with a remainder of 103.
Put 4 as the next digit of the answer. 
Result so far: 129894.0
Deduct 556 from 659 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
If we divide 1030 by 139, we get 7 and a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 129894.7
The remainder is 57 after subtracting 973 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
570 divided by 139 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 129894.74
Subtract 556 from 570 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
139 goes into 140 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 129894.741
Deduct 139 from 140 and we're left 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.

Advancing to step 12:
When dividing 10 by 139, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 129894.741
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.

Moving on to step 13:
139 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 129894.741
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 129894.741, with a leftover of 0.0001.
