Let's divide 84102782 by 109
The aim is to understand the frequency of 109 in 84102782.

Going ahead to step 1:
109 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 109

Advancing to step 2:
When dividing 84 by 109, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 109

Advancing to step 3:
If we divide 841 by 109, we get 7 and a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 763 from 841 leaves us with 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 109

Let's proceed to step 4:
109 can be fit into 780 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we subtract 763 from 780, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 109

Going ahead to step 5:
When dividing 172 by 109, we get 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 771.0
If we subtract 109 from 172, we get 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 109

Let's proceed to step 6:
109 can be fit into 637 5 times, resulting in a remainder of 92.
Use 5 as the next digit of our solution. 
Result so far: 7715.0
If we take 545 away from 637, we end up with 92.
Grab the next digit (8) from the dividend, add it to 92, then carry on: 928 / 109

Let's proceed to step 7:
109 goes into 928 8 times with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 77158.0
Subtracting 872 from 928 leaves us with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 109

Advancing to step 8:
109 can be fit into 562 5 times, resulting in a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 771585.0
The remainder is 17 after subtracting 545 from 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
The number 109 fits into 170 1 times, leaving a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 771585.1
If we take 109 away from 170, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
When dividing 610 by 109, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 771585.15
Deduct 545 from 610 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
The number 109 fits into 650 5 times, leaving a remainder of 105.
The next digit of our result is 5. 
Result so far: 771585.155
Subtracting 545 from 650 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 771585.155 with a remaining 0.0105.
