We're dividing 23661032 by 309 
The aim is to understand the frequency of 309 in 23661032.

On to step 1:
309 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 309

Going ahead to step 2:
The number 309 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 309

Moving on to step 3:
The number 309 fits into 236 0 times, leaving a remainder of 236.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 236, we get 236.
Fetch the next digit (6) from the dividend, attach it to 236 and continue: 2366 / 309

Let's proceed to step 4:
The number 309 fits into 2366 7 times, leaving a remainder of 203.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 2163 from 2366 and we're left with 203.
Take the next digit (1) from the dividend and append it to 203, then repeat: 2031 / 309

Advancing to step 5:
If we divide 2031 by 309, we get 6 and a remainder of 177.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 1854 from 2031 and we're left with 177.
Fetch the next digit (0) from the dividend, attach it to 177 and continue: 1770 / 309

Step 6:
The number 309 fits into 1770 5 times, leaving a remainder of 225.
The next digit of our result is 5. 
Result so far: 765.0
Deduct 1545 from 1770 and we're left with 225.
Append the next digit (3) from the dividend to 225 and continue with: 2253 / 309

Moving on to step 7:
309 can be fit into 2253 7 times, resulting in a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 7657.0
If we take 2163 away from 2253, we end up with 90.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 309

Advancing to step 8:
If we divide 902 by 309, we get 2 and a remainder of 284.
The next digit of our result is 2. 
Result so far: 76572.0
If we subtract 618 from 902, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 9:
When dividing 2840 by 309, we get 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 76572.9
Subtracting 2781 from 2840 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
590 divided by 309 is 1 with a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 76572.91
If we subtract 309 from 590, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 11:
309 goes into 2810 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 76572.919
If we subtract 2781 from 2810, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
When dividing 290 by 309, we get 0 with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 76572.919
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 13:
309 can be fit into 2900 9 times, resulting in a remainder of 119.
Write down 9 as next digit of the result. 
Result so far: 76572.91909
Deduct 2781 from 2900 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 14:
If we divide 1190 by 309, we get 3 and a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 76572.919093
The remainder is 263 after subtracting 927 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 15:
The number 309 fits into 2630 8 times, leaving a remainder of 158.
Record the quotient 8 as the next digit in the result. 
Result so far: 76572.9190938
Subtract 2472 from 2630 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 16:
When dividing 1580 by 309, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 76572.91909385
If we take 1545 away from 1580, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 76572.91909385, and the remainder is 3.5e-08.
