Let's divide 31397959 by 109
The aim is to understand the frequency of 109 in 31397959.

Advancing to step 1:
If we divide 3 by 109, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 109

Let's proceed to step 2:
When dividing 31 by 109, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 109

On to step 3:
109 goes into 313 2 times with a remainder of 95.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 95 after subtracting 218 from 313.
Take the next digit (9) from the dividend and append it to 95, then repeat: 959 / 109

Advancing to step 4:
The number 109 fits into 959 8 times, leaving a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 872 away from 959, we end up with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 109

Step 5:
If we divide 877 by 109, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 288.0
Subtracting 872 from 877 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 109

Advancing to step 6:
If we divide 59 by 109, we get 0 and a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 2880.0
The remainder is 59 after subtracting 0 from 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 109

Let's proceed to step 7:
109 can be fit into 595 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 28805.0
The remainder is 50 after subtracting 545 from 595.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 109

Let's proceed to step 8:
When dividing 509 by 109, we get 4 with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 288054.0
Subtract 436 from 509 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
109 goes into 730 6 times with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 288054.6
The remainder is 76 after subtracting 654 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
760 divided by 109 is 6 with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 288054.66
Deduct 654 from 760 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 288054.66 with a balance of 0.106.
