We're dividing 30597292 by 306 
The aim is to understand the frequency of 306 in 30597292.

Advancing to step 1:
306 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 306

Going ahead to step 2:
306 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 306

Step 3:
The number 306 fits into 305 0 times, leaving a remainder of 305.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 305, we end up with 305.
Grab the next digit (9) from the dividend, add it to 305, then carry on: 3059 / 306

Let's proceed to step 4:
306 goes into 3059 9 times with a remainder of 305.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 305 after subtracting 2754 from 3059.
Take the next digit (7) from the dividend and append it to 305, then repeat: 3057 / 306

On to step 5:
306 goes into 3057 9 times with a remainder of 303.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 2754 from 3057 and we're left with 303.
Take the next digit (2) from the dividend and append it to 303, then repeat: 3032 / 306

Let's proceed to step 6:
When dividing 3032 by 306, we get 9 with a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 999.0
If we subtract 2754 from 3032, we get 278.
Include the next digit (9) from the dividend after 278, then repeat: 2789 / 306

Going ahead to step 7:
306 goes into 2789 9 times with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 9999.0
If we subtract 2754 from 2789, we get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 306

Moving on to step 8:
352 divided by 306 is 1 with a remainder of 46.
The next digit of our result is 1. 
Result so far: 99991.0
If we subtract 306 from 352, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
If we divide 460 by 306, we get 1 and a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 99991.1
Deduct 306 from 460 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 10:
1540 divided by 306 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 99991.15
The remainder is 10 after subtracting 1530 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
If we divide 100 by 306, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 99991.15
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
306 can be fit into 1000 3 times, resulting in a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 99991.1503
If we take 918 away from 1000, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 13:
820 divided by 306 is 2 with a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 99991.15032
If we subtract 612 from 820, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
If we divide 2080 by 306, we get 6 and a remainder of 244.
Put 6 as the next digit of the answer. 
Result so far: 99991.150326
Subtracting 1836 from 2080 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 15:
If we divide 2440 by 306, we get 7 and a remainder of 298.
Record the quotient 7 as the next digit in the result. 
Result so far: 99991.1503267
Subtract 2142 from 2440 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 16:
If we divide 2980 by 306, we get 9 and a remainder of 226.
Write down 9 as next digit of the result. 
Result so far: 99991.15032679
If we take 2754 away from 2980, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

After the division, we end up with 99991.15032679 and a remainder of 2.26e-07.
