We look at the division of 26664755 by 309 
The aim is to understand the frequency of 309 in 26664755.

Going ahead to step 1:
309 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 309

Let's proceed to step 2:
309 can be fit into 26 0 times, resulting in a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 309

On to step 3:
309 goes into 266 0 times with a remainder of 266.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 266, we end up with 266.
Grab the next digit (6) from the dividend, add it to 266, then carry on: 2666 / 309

Step 4:
When dividing 2666 by 309, we get 8 with a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 2472 away from 2666, we end up with 194.
Take the next digit (4) from the dividend and append it to 194, then repeat: 1944 / 309

Going ahead to step 5:
If we divide 1944 by 309, we get 6 and a remainder of 90.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 1854 away from 1944, we end up with 90.
Grab the next digit (7) from the dividend, add it to 90, then carry on: 907 / 309

Moving on to step 6:
When dividing 907 by 309, we get 2 with a remainder of 289.
Use 2 as the next digit of our solution. 
Result so far: 862.0
The remainder is 289 after subtracting 618 from 907.
Append the next digit (5) from the dividend to 289 and continue with: 2895 / 309

Advancing to step 7:
309 can be fit into 2895 9 times, resulting in a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 8629.0
Deduct 2781 from 2895 and we're left with 114.
Bring next digit (5) of the dividend behind the 114 and repeat the process: 1145 / 309

Step 8:
1145 divided by 309 is 3 with a remainder of 218.
Put 3 as the next digit of the answer. 
Result so far: 86293.0
Deduct 927 from 1145 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 9:
When dividing 2180 by 309, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 86293.7
Deduct 2163 from 2180 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
309 can be fit into 170 0 times, resulting in a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 86293.7
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
When dividing 1700 by 309, we get 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 86293.705
The remainder is 155 after subtracting 1545 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 12:
1550 divided by 309 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 86293.7055
If we take 1545 away from 1550, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 86293.7055, with a leftover of 5e-05.
