Let's divide 82710999 by 309
The aim is to understand the frequency of 309 in 82710999.

Moving on to step 1:
If we divide 8 by 309, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 309

On to step 2:
When dividing 82 by 309, we get 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Append the next digit (7) from the dividend to 82 and continue with: 827 / 309

Advancing to step 3:
309 can be fit into 827 2 times, resulting in a remainder of 209.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 618 from 827 and we're left with 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 309

Let's proceed to step 4:
When dividing 2091 by 309, we get 6 with a remainder of 237.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 1854 from 2091 leaves us with 237.
Take the next digit (0) from the dividend and append it to 237, then repeat: 2370 / 309

Going ahead to step 5:
309 goes into 2370 7 times with a remainder of 207.
Use 7 as the next digit of our solution. 
Result so far: 267.0
Subtracting 2163 from 2370 leaves us with 207.
Include the next digit (9) from the dividend after 207, then repeat: 2079 / 309

Going ahead to step 6:
309 can be fit into 2079 6 times, resulting in a remainder of 225.
Record the quotient 6 as the next digit in the result. 
Result so far: 2676.0
The remainder is 225 after subtracting 1854 from 2079.
Bring next digit (9) of the dividend behind the 225 and repeat the process: 2259 / 309

Moving on to step 7:
2259 divided by 309 is 7 with a remainder of 96.
Write down 7 as next digit of the result. 
Result so far: 26767.0
Subtract 2163 from 2259 to get 96.
Grab the next digit (9) from the dividend, add it to 96, then carry on: 969 / 309

Moving on to step 8:
If we divide 969 by 309, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 267673.0
Deduct 927 from 969 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
When dividing 420 by 309, we get 1 with a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 267673.1
The remainder is 111 after subtracting 309 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 10:
When dividing 1110 by 309, we get 3 with a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 267673.13
If we subtract 927 from 1110, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 11:
1830 divided by 309 is 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 267673.135
Subtracting 1545 from 1830 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 12:
309 can be fit into 2850 9 times, resulting in a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 267673.1359
Deduct 2781 from 2850 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 13:
When dividing 690 by 309, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 267673.13592
The remainder is 72 after subtracting 618 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
720 divided by 309 is 2 with a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 267673.135922
If we subtract 618 from 720, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 267673.135922, with a leftover of 1.02e-05.
