We're dividing 85279929 by 139 
The aim is to understand the frequency of 139 in 85279929.

Step 1:
8 divided by 139 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 139

Step 2:
If we divide 85 by 139, we get 0 and a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 139

Going ahead to step 3:
852 divided by 139 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 834 away from 852, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 139

Advancing to step 4:
139 can be fit into 187 1 times, resulting in a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
The remainder is 48 after subtracting 139 from 187.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 139

Moving on to step 5:
The number 139 fits into 489 3 times, leaving a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 613.0
If we subtract 417 from 489, we get 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 139

Going ahead to step 6:
When dividing 729 by 139, we get 5 with a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 6135.0
Subtract 695 from 729 to get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 139

Moving on to step 7:
139 goes into 342 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 61352.0
Subtracting 278 from 342 leaves us with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 139

Step 8:
139 goes into 649 4 times with a remainder of 93.
Use 4 as the next digit of our solution. 
Result so far: 613524.0
If we subtract 556 from 649, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
When dividing 930 by 139, we get 6 with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 613524.6
If we take 834 away from 930, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 10:
When dividing 960 by 139, we get 6 with a remainder of 126.
Write down 6 as next digit of the result. 
Result so far: 613524.66
Subtracting 834 from 960 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

After the division, we end up with 613524.66 and a remainder of 0.126.
