We look at the division of 43489788 by 131 
The aim is to understand the frequency of 131 in 43489788.

Moving on to step 1:
If we divide 4 by 131, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 131

On to step 2:
131 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 131

Step 3:
When dividing 434 by 131, we get 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 41 after subtracting 393 from 434.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 131

Let's proceed to step 4:
418 divided by 131 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 33.0
The remainder is 25 after subtracting 393 from 418.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 131

Step 5:
131 can be fit into 259 1 times, resulting in a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 331.0
Subtracting 131 from 259 leaves us with 128.
Fetch the next digit (7) from the dividend, attach it to 128 and continue: 1287 / 131

Step 6:
When dividing 1287 by 131, we get 9 with a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 3319.0
If we take 1179 away from 1287, we end up with 108.
Include the next digit (8) from the dividend after 108, then repeat: 1088 / 131

Step 7:
If we divide 1088 by 131, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 33198.0
Subtracting 1048 from 1088 leaves us with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 131

On to step 8:
408 divided by 131 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 331983.0
Subtracting 393 from 408 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
131 goes into 150 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 331983.1
If we take 131 away from 150, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
131 goes into 190 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 331983.11
If we subtract 131 from 190, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

In conclusion, the division gives 331983.11 with a balance of 0.059.
