We're dividing 65807270 by 139 
The aim is to understand the frequency of 139 in 65807270.

Going ahead to step 1:
139 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 139

Let's proceed to step 2:
65 divided by 139 is 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 139

Step 3:
If we divide 658 by 139, we get 4 and a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 556 from 658 leaves us with 102.
Append the next digit (0) from the dividend to 102 and continue with: 1020 / 139

On to step 4:
When dividing 1020 by 139, we get 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 973 away from 1020, we end up with 47.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 139

Step 5:
139 can be fit into 477 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 473.0
Subtract 417 from 477 to get 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 139

On to step 6:
If we divide 602 by 139, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4734.0
The remainder is 46 after subtracting 556 from 602.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 139

Moving on to step 7:
If we divide 467 by 139, we get 3 and a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 47343.0
If we take 417 away from 467, we end up with 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 139

On to step 8:
139 can be fit into 500 3 times, resulting in a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 473433.0
The remainder is 83 after subtracting 417 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 9:
If we divide 830 by 139, we get 5 and a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 473433.5
If we subtract 695 from 830, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 10:
The number 139 fits into 1350 9 times, leaving a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 473433.59
If we subtract 1251 from 1350, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 11:
When dividing 990 by 139, we get 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 473433.597
Subtracting 973 from 990 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
The number 139 fits into 170 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 473433.5971
Deduct 139 from 170 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
139 goes into 310 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 473433.59712
The remainder is 32 after subtracting 278 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
If we divide 320 by 139, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 473433.597122
Subtracting 278 from 320 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 473433.597122 with a remaining 4.2e-06.
