We look at the division of 51002240 by 109 
The aim is to understand the frequency of 109 in 51002240.

Advancing to step 1:
5 divided by 109 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 109

On to step 2:
109 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 109

Moving on to step 3:
When dividing 510 by 109, we get 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 436 from 510 leaves us with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 109

Moving on to step 4:
The number 109 fits into 740 6 times, leaving a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 654 away from 740, we end up with 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 109

On to step 5:
When dividing 862 by 109, we get 7 with a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 467.0
Subtract 763 from 862 to get 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 109

Let's proceed to step 6:
109 goes into 992 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 4679.0
Deduct 981 from 992 and we're left with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 109

Let's proceed to step 7:
If we divide 114 by 109, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 46791.0
Subtracting 109 from 114 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 109

On to step 8:
When dividing 50 by 109, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 467910.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 109, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 467910.4
The remainder is 64 after subtracting 436 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
109 can be fit into 640 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 467910.45
The remainder is 95 after subtracting 545 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 11:
If we divide 950 by 109, we get 8 and a remainder of 78.
The next digit of our result is 8. 
Result so far: 467910.458
Deduct 872 from 950 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 12:
780 divided by 109 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 467910.4587
The remainder is 17 after subtracting 763 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
109 can be fit into 170 1 times, resulting in a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 467910.45871
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.

Going ahead to step 14:
610 divided by 109 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 467910.458715
Subtract 545 from 610 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 15:
When dividing 650 by 109, we get 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 467910.4587155
If we subtract 545 from 650, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

In conclusion, the division gives 467910.4587155 with a balance of 1.05e-06.
