We divide 86597049 by 109
The aim is to understand the frequency of 109 in 86597049.

Moving on to step 1:
When dividing 8 by 109, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 109

Let's proceed to step 2:
109 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 109

Moving on to step 3:
109 goes into 865 7 times with a remainder of 102.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 763 from 865 and we're left with 102.
Bring next digit (9) of the dividend behind the 102 and repeat the process: 1029 / 109

Going ahead to step 4:
109 can be fit into 1029 9 times, resulting in a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 981 from 1029 to get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 109

Let's proceed to step 5:
If we divide 487 by 109, we get 4 and a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 794.0
Subtract 436 from 487 to get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 109

Advancing to step 6:
When dividing 510 by 109, we get 4 with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 7944.0
Subtract 436 from 510 to get 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 109

Let's proceed to step 7:
When dividing 744 by 109, we get 6 with a remainder of 90.
Put 6 as the next digit of the answer. 
Result so far: 79446.0
The remainder is 90 after subtracting 654 from 744.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 109

Let's proceed to step 8:
If we divide 909 by 109, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 794468.0
Subtract 872 from 909 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
370 divided by 109 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 794468.3
Deduct 327 from 370 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
430 divided by 109 is 3 with a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 794468.33
Deduct 327 from 430 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

After the division, we end up with 794468.33 and a remainder of 0.103.
