We're dividing 43958482 by 125 
The aim is to understand the frequency of 125 in 43958482.

Advancing to step 1:
When dividing 4 by 125, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 125

Step 2:
When dividing 43 by 125, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 125

On to step 3:
125 goes into 439 3 times with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 375 away from 439, we end up with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 125

Going ahead to step 4:
If we divide 645 by 125, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 20 after subtracting 625 from 645.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 125

Moving on to step 5:
125 can be fit into 208 1 times, resulting in a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 351.0
Deduct 125 from 208 and we're left with 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 125

Let's proceed to step 6:
125 can be fit into 834 6 times, resulting in a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 3516.0
Subtracting 750 from 834 leaves us with 84.
Take the next digit (8) from the dividend and append it to 84, then repeat: 848 / 125

Going ahead to step 7:
When dividing 848 by 125, we get 6 with a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 35166.0
Subtracting 750 from 848 leaves us with 98.
Fetch the next digit (2) from the dividend, attach it to 98 and continue: 982 / 125

Moving on to step 8:
125 goes into 982 7 times with a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 351667.0
Subtracting 875 from 982 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 9:
If we divide 1070 by 125, we get 8 and a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 351667.8
Subtract 1000 from 1070 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
When dividing 700 by 125, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 351667.85
Subtracting 625 from 700 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
If we divide 750 by 125, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 351667.856
Subtracting 750 from 750 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 125 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 351667.856
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
125 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 351667.856
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 351667.856 with a remaining 0.0.
