We look at the division of 35266597 by 309 
The aim is to understand the frequency of 309 in 35266597.

Moving on to step 1:
If we divide 3 by 309, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 309

Advancing to step 2:
35 divided by 309 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 309

Going ahead to step 3:
When dividing 352 by 309, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 309 from 352 to get 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 309

Moving on to step 4:
The number 309 fits into 436 1 times, leaving a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 309 from 436, we get 127.
Bring next digit (6) of the dividend behind the 127 and repeat the process: 1276 / 309

Going ahead to step 5:
The number 309 fits into 1276 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we subtract 1236 from 1276, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 309

Moving on to step 6:
309 goes into 405 1 times with a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 1141.0
If we subtract 309 from 405, we get 96.
Include the next digit (9) from the dividend after 96, then repeat: 969 / 309

Step 7:
If we divide 969 by 309, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 11413.0
If we subtract 927 from 969, we get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 309

Moving on to step 8:
If we divide 427 by 309, we get 1 and a remainder of 118.
Record the quotient 1 as the next digit in the result. 
Result so far: 114131.0
Subtract 309 from 427 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 9:
If we divide 1180 by 309, we get 3 and a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 114131.3
The remainder is 253 after subtracting 927 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 10:
The number 309 fits into 2530 8 times, leaving a remainder of 58.
The next digit of our result is 8. 
Result so far: 114131.38
Deduct 2472 from 2530 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
When dividing 580 by 309, we get 1 with a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 114131.381
Deduct 309 from 580 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 12:
2710 divided by 309 is 8 with a remainder of 238.
Record the quotient 8 as the next digit in the result. 
Result so far: 114131.3818
Deduct 2472 from 2710 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 13:
The number 309 fits into 2380 7 times, leaving a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 114131.38187
If we subtract 2163 from 2380, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 14:
If we divide 2170 by 309, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 114131.381877
Deduct 2163 from 2170 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 114131.381877 with a remainder of 7e-07.
