We're dividing 30212864 by 139 
The aim is to understand the frequency of 139 in 30212864.

On to step 1:
When dividing 3 by 139, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 139

Let's proceed to step 2:
When dividing 30 by 139, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 139

Let's proceed to step 3:
The number 139 fits into 302 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 278 from 302 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 139

Advancing to step 4:
139 goes into 241 1 times with a remainder of 102.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 139 from 241 and we're left with 102.
Bring next digit (2) of the dividend behind the 102 and repeat the process: 1022 / 139

Going ahead to step 5:
When dividing 1022 by 139, we get 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 217.0
The remainder is 49 after subtracting 973 from 1022.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 139

On to step 6:
If we divide 498 by 139, we get 3 and a remainder of 81.
The next digit of our result is 3. 
Result so far: 2173.0
Subtract 417 from 498 to get 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 139

Let's proceed to step 7:
If we divide 816 by 139, we get 5 and a remainder of 121.
Record the quotient 5 as the next digit in the result. 
Result so far: 21735.0
Deduct 695 from 816 and we're left with 121.
Bring next digit (4) of the dividend behind the 121 and repeat the process: 1214 / 139

Step 8:
1214 divided by 139 is 8 with a remainder of 102.
The next digit of our result is 8. 
Result so far: 217358.0
Subtracting 1112 from 1214 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 9:
1020 divided by 139 is 7 with a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 217358.7
Subtract 973 from 1020 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
If we divide 470 by 139, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 217358.73
The remainder is 53 after subtracting 417 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
If we divide 530 by 139, we get 3 and a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 217358.733
The remainder is 113 after subtracting 417 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

In conclusion, the division gives 217358.733 with a balance of 0.0113.
