We look at the division of 81734934 by 109 
The aim is to understand the frequency of 109 in 81734934.

Advancing to step 1:
The number 109 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 109

On to step 2:
When dividing 81 by 109, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (7) from the dividend, add it to 81, then carry on: 817 / 109

Step 3:
109 can be fit into 817 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 763 away from 817, we end up with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 109

Moving on to step 4:
When dividing 543 by 109, we get 4 with a remainder of 107.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
The remainder is 107 after subtracting 436 from 543.
Grab the next digit (4) from the dividend, add it to 107, then carry on: 1074 / 109

Step 5:
109 can be fit into 1074 9 times, resulting in a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 749.0
Subtract 981 from 1074 to get 93.
Fetch the next digit (9) from the dividend, attach it to 93 and continue: 939 / 109

Moving on to step 6:
When dividing 939 by 109, we get 8 with a remainder of 67.
The next digit of our result is 8. 
Result so far: 7498.0
Deduct 872 from 939 and we're left with 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 109

Let's proceed to step 7:
673 divided by 109 is 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 74986.0
Subtract 654 from 673 to get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 109

Going ahead to step 8:
194 divided by 109 is 1 with a remainder of 85.
The next digit of our result is 1. 
Result so far: 749861.0
Deduct 109 from 194 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
109 goes into 850 7 times with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 749861.7
Subtracting 763 from 850 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 10:
109 can be fit into 870 7 times, resulting in a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 749861.77
Subtract 763 from 870 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 749861.77 and a remainder of 0.107.
