We look at the division of 56068972 by 306 
The aim is to understand the frequency of 306 in 56068972.

On to step 1:
The number 306 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 306

Going ahead to step 2:
56 divided by 306 is 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 306

Let's proceed to step 3:
When dividing 560 by 306, we get 1 with a remainder of 254.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 254 after subtracting 306 from 560.
Append the next digit (6) from the dividend to 254 and continue with: 2546 / 306

Step 4:
The number 306 fits into 2546 8 times, leaving a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 98 after subtracting 2448 from 2546.
Fetch the next digit (8) from the dividend, attach it to 98 and continue: 988 / 306

Advancing to step 5:
If we divide 988 by 306, we get 3 and a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 183.0
If we subtract 918 from 988, we get 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 306

Going ahead to step 6:
306 can be fit into 709 2 times, resulting in a remainder of 97.
The next digit of our result is 2. 
Result so far: 1832.0
Subtract 612 from 709 to get 97.
Fetch the next digit (7) from the dividend, attach it to 97 and continue: 977 / 306

On to step 7:
306 can be fit into 977 3 times, resulting in a remainder of 59.
The next digit of our result is 3. 
Result so far: 18323.0
Deduct 918 from 977 and we're left with 59.
Include the next digit (2) from the dividend after 59, then repeat: 592 / 306

On to step 8:
306 can be fit into 592 1 times, resulting in a remainder of 286.
Use 1 as the next digit of our solution. 
Result so far: 183231.0
If we take 306 away from 592, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 9:
2860 divided by 306 is 9 with a remainder of 106.
The number 9 becomes the next digit in our result. 
Result so far: 183231.9
If we subtract 2754 from 2860, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
1060 divided by 306 is 3 with a remainder of 142.
The next digit of our result is 3. 
Result so far: 183231.93
Deduct 918 from 1060 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 11:
306 can be fit into 1420 4 times, resulting in a remainder of 196.
The next digit of our result is 4. 
Result so far: 183231.934
Deduct 1224 from 1420 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 12:
If we divide 1960 by 306, we get 6 and a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 183231.9346
If we take 1836 away from 1960, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 13:
1240 divided by 306 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 183231.93464
The remainder is 16 after subtracting 1224 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
306 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 183231.93464
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
If we divide 1600 by 306, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 183231.9346405
The remainder is 70 after subtracting 1530 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
When dividing 700 by 306, we get 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 183231.93464052
Subtract 612 from 700 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 183231.93464052 with a remainder of 8.8e-08.
