12493993 divided by 109 
The aim is to understand the frequency of 109 in 12493993.

Moving on to step 1:
If we divide 1 by 109, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 109

Step 2:
The number 109 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 109

Advancing to step 3:
The number 109 fits into 124 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 109 from 124 to get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 109

On to step 4:
If we divide 159 by 109, we get 1 and a remainder of 50.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 109 from 159, we get 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 109

Step 5:
109 can be fit into 503 4 times, resulting in a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 67 after subtracting 436 from 503.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 109

Let's proceed to step 6:
The number 109 fits into 679 6 times, leaving a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 1146.0
If we subtract 654 from 679, we get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 109

Going ahead to step 7:
109 can be fit into 259 2 times, resulting in a remainder of 41.
The next digit of our result is 2. 
Result so far: 11462.0
If we take 218 away from 259, we end up with 41.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 109

Step 8:
When dividing 413 by 109, we get 3 with a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 114623.0
The remainder is 86 after subtracting 327 from 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
When dividing 860 by 109, we get 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 114623.7
If we subtract 763 from 860, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 10:
970 divided by 109 is 8 with a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 114623.78
Deduct 872 from 970 and we're left 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.

Step 11:
If we divide 980 by 109, we get 8 and a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 114623.788
If we subtract 872 from 980, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Our division results in 114623.788 with a remaining 0.0108.
