86511360 divided by 109 
The aim is to understand the frequency of 109 in 86511360.

Step 1:
8 divided by 109 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 109

On to step 2:
The number 109 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 109

Advancing to step 3:
109 can be fit into 865 7 times, resulting in a remainder of 102.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 763 from 865 to get 102.
Append the next digit (1) from the dividend to 102 and continue with: 1021 / 109

On to step 4:
109 can be fit into 1021 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we take 981 away from 1021, we end up with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 109

Going ahead to step 5:
If we divide 401 by 109, we get 3 and a remainder of 74.
The next digit of our result is 3. 
Result so far: 793.0
Subtracting 327 from 401 leaves us with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 109

Let's proceed to step 6:
If we divide 743 by 109, we get 6 and a remainder of 89.
The next digit of our result is 6. 
Result so far: 7936.0
Subtracting 654 from 743 leaves us with 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 109

Going ahead to step 7:
When dividing 896 by 109, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 79368.0
If we subtract 872 from 896, we get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 109

Going ahead to step 8:
109 goes into 240 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 793682.0
The remainder is 22 after subtracting 218 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
109 goes into 220 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 793682.2
Deduct 218 from 220 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
The number 109 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 793682.2
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
109 goes into 200 1 times with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 793682.201
Subtracting 109 from 200 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 12:
When dividing 910 by 109, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 793682.2018
The remainder is 38 after subtracting 872 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
109 can be fit into 380 3 times, resulting in a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 793682.20183
If we take 327 away from 380, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 14:
If we divide 530 by 109, we get 4 and a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 793682.201834
Subtracting 436 from 530 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 15:
When dividing 940 by 109, we get 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 793682.2018348
If we take 872 away from 940, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 16:
If we divide 680 by 109, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 793682.20183486
Subtracting 654 from 680 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 793682.20183486 with a remaining 2.6e-08.
