12937136 divided by 109 
The aim is to understand the frequency of 109 in 12937136.

Moving on to step 1:
If we divide 1 by 109, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 109

Advancing to step 2:
12 divided by 109 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 109

Advancing to step 3:
The number 109 fits into 129 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 109 from 129, we get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 109

On to step 4:
The number 109 fits into 203 1 times, leaving a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 109 from 203 and we're left with 94.
Append the next digit (7) from the dividend to 94 and continue with: 947 / 109

Step 5:
947 divided by 109 is 8 with a remainder of 75.
The next digit of our result is 8. 
Result so far: 118.0
If we take 872 away from 947, we end up with 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 109

Advancing to step 6:
If we divide 751 by 109, we get 6 and a remainder of 97.
The next digit of our result is 6. 
Result so far: 1186.0
Subtract 654 from 751 to get 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 109

Let's proceed to step 7:
973 divided by 109 is 8 with a remainder of 101.
The next digit of our result is 8. 
Result so far: 11868.0
If we subtract 872 from 973, we get 101.
Take the next digit (6) from the dividend and append it to 101, then repeat: 1016 / 109

On to step 8:
109 can be fit into 1016 9 times, resulting in a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 118689.0
Subtract 981 from 1016 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 109 fits into 350 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 118689.3
Subtracting 327 from 350 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
If we divide 230 by 109, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 118689.32
The remainder is 12 after subtracting 218 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
109 goes into 120 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 118689.321
Deduct 109 from 120 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
When dividing 110 by 109, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 118689.3211
Deduct 109 from 110 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 118689.3211 with a balance of 1e-05.
