35712748 ÷ 109 
The aim is to understand the frequency of 109 in 35712748.

Step 1:
If we divide 3 by 109, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 109

Let's proceed to step 2:
If we divide 35 by 109, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 109

Going ahead to step 3:
When dividing 357 by 109, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 327 from 357 to get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 109

Moving on to step 4:
When dividing 301 by 109, we get 2 with a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
The remainder is 83 after subtracting 218 from 301.
Bring next digit (2) of the dividend behind the 83 and repeat the process: 832 / 109

Let's proceed to step 5:
109 goes into 832 7 times with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 327.0
If we subtract 763 from 832, we get 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 109

On to step 6:
When dividing 697 by 109, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 3276.0
Deduct 654 from 697 and we're left with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 109

Advancing to step 7:
109 can be fit into 434 3 times, resulting in a remainder of 107.
The number 3 becomes the next digit in our result. 
Result so far: 32763.0
The remainder is 107 after subtracting 327 from 434.
Include the next digit (8) from the dividend after 107, then repeat: 1078 / 109

Let's proceed to step 8:
109 goes into 1078 9 times with a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 327639.0
The remainder is 97 after subtracting 981 from 1078.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
109 can be fit into 970 8 times, resulting in a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 327639.8
Subtracting 872 from 970 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 10:
109 goes into 980 8 times with a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 327639.88
Deduct 872 from 980 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The quotient of the division is 327639.88, and the remainder is 0.108.
