We're dividing 80345422 by 309 
The aim is to understand the frequency of 309 in 80345422.

Moving on to step 1:
309 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 309

Going ahead to step 2:
80 divided by 309 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 309

Moving on to step 3:
803 divided by 309 is 2 with a remainder of 185.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 185 after subtracting 618 from 803.
Include the next digit (4) from the dividend after 185, then repeat: 1854 / 309

Moving on to step 4:
When dividing 1854 by 309, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 1854 from 1854 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 309

Advancing to step 5:
The number 309 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 260.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 309

Advancing to step 6:
If we divide 54 by 309, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 2600.0
Subtract 0 from 54 to get 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 309

Step 7:
309 goes into 542 1 times with a remainder of 233.
Put 1 as the next digit of the answer. 
Result so far: 26001.0
Subtracting 309 from 542 leaves us with 233.
Bring next digit (2) of the dividend behind the 233 and repeat the process: 2332 / 309

On to step 8:
If we divide 2332 by 309, we get 7 and a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 260017.0
If we subtract 2163 from 2332, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 9:
If we divide 1690 by 309, we get 5 and a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 260017.5
If we subtract 1545 from 1690, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 10:
When dividing 1450 by 309, we get 4 with a remainder of 214.
Write down 4 as next digit of the result. 
Result so far: 260017.54
If we take 1236 away from 1450, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
The number 309 fits into 2140 6 times, leaving a remainder of 286.
Record the quotient 6 as the next digit in the result. 
Result so far: 260017.546
If we take 1854 away from 2140, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 12:
The number 309 fits into 2860 9 times, leaving a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 260017.5469
The remainder is 79 after subtracting 2781 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 13:
309 goes into 790 2 times with a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 260017.54692
The remainder is 172 after subtracting 618 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 14:
The number 309 fits into 1720 5 times, leaving a remainder of 175.
The next digit of our result is 5. 
Result so far: 260017.546925
If we subtract 1545 from 1720, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 15:
1750 divided by 309 is 5 with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 260017.5469255
If we subtract 1545 from 1750, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final result is 260017.5469255 with a remainder of 2.05e-06.
