8203088 ÷ 109 
The aim is to understand the frequency of 109 in 8203088.

Let's proceed 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
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 109

Advancing to step 2:
The number 109 fits into 82 0 times, leaving a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Include the next digit (0) from the dividend after 82, then repeat: 820 / 109

Let's proceed to step 3:
109 can be fit into 820 7 times, resulting in a remainder of 57.
The next digit of our result is 7. 
Result so far: 7.0
If we take 763 away from 820, we end up with 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 109

Let's proceed to step 4:
573 divided by 109 is 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we subtract 545 from 573, we get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 109

Step 5:
109 can be fit into 280 2 times, resulting in a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 752.0
Subtract 218 from 280 to get 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 109

On to step 6:
The number 109 fits into 628 5 times, leaving a remainder of 83.
The next digit of our result is 5. 
Result so far: 7525.0
If we subtract 545 from 628, we get 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 109

On to step 7:
When dividing 838 by 109, we get 7 with a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 75257.0
Deduct 763 from 838 and we're left 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.

Moving on to step 8:
If we divide 750 by 109, we get 6 and a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 75257.6
If we take 654 away from 750, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 9:
960 divided by 109 is 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 75257.68
Deduct 872 from 960 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
When dividing 880 by 109, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 75257.688
If we take 872 away from 880, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 75257.688 and a remainder of 0.0008.
