Let's divide 12031202 by 139
The aim is to understand the frequency of 139 in 12031202.

Going ahead to step 1:
When dividing 1 by 139, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 139

Step 2:
12 divided by 139 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 139

Going ahead to step 3:
When dividing 120 by 139, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 120, we get 120.
Append the next digit (3) from the dividend to 120 and continue with: 1203 / 139

Advancing to step 4:
If we divide 1203 by 139, we get 8 and a remainder of 91.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 1112 away from 1203, we end up with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 139

Let's proceed to step 5:
When dividing 911 by 139, we get 6 with a remainder of 77.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we subtract 834 from 911, we get 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 139

On to step 6:
772 divided by 139 is 5 with a remainder of 77.
Use 5 as the next digit of our solution. 
Result so far: 865.0
If we subtract 695 from 772, we get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 139

Let's proceed to step 7:
139 can be fit into 770 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 8655.0
Subtracting 695 from 770 leaves us with 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 139

Going ahead to step 8:
If we divide 752 by 139, we get 5 and a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 86555.0
Subtracting 695 from 752 leaves us with 57.
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 9:
570 divided by 139 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 86555.4
The remainder is 14 after subtracting 556 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
The number 139 fits into 140 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 86555.41
Subtracting 139 from 140 leaves us 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.

On to step 11:
If we divide 10 by 139, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 86555.41
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
139 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 86555.41
If we take 0 away from 100, we end up with 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 86555.41, with a leftover of 0.001.
