56584211 ÷ 300 
The aim is to understand the frequency of 300 in 56584211.

On to step 1:
When dividing 5 by 300, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 300

Moving on to step 2:
The number 300 fits into 56 0 times, leaving a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 300

Step 3:
If we divide 565 by 300, we get 1 and a remainder of 265.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 300 from 565 to get 265.
Include the next digit (8) from the dividend after 265, then repeat: 2658 / 300

Going ahead to step 4:
300 goes into 2658 8 times with a remainder of 258.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 2400 from 2658, we get 258.
Fetch the next digit (4) from the dividend, attach it to 258 and continue: 2584 / 300

Moving on to step 5:
The number 300 fits into 2584 8 times, leaving a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Deduct 2400 from 2584 and we're left with 184.
Grab the next digit (2) from the dividend, add it to 184, then carry on: 1842 / 300

On to step 6:
300 can be fit into 1842 6 times, resulting in a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 1886.0
Subtract 1800 from 1842 to get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 300

Going ahead to step 7:
421 divided by 300 is 1 with a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 18861.0
If we subtract 300 from 421, we get 121.
Fetch the next digit (1) from the dividend, attach it to 121 and continue: 1211 / 300

Moving on to step 8:
1211 divided by 300 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 188614.0
Subtract 1200 from 1211 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
When dividing 110 by 300, we get 0 with a remainder of 110.
The next digit of our result is 0. 
Result so far: 188614.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
If we divide 1100 by 300, we get 3 and a remainder of 200.
The next digit of our result is 3. 
Result so far: 188614.03
Subtract 900 from 1100 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
300 goes into 2000 6 times with a remainder of 200.
The next digit of our result is 6. 
Result so far: 188614.036
Subtract 1800 from 2000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
2000 divided by 300 is 6 with a remainder of 200.
The next digit of our result is 6. 
Result so far: 188614.0366
Subtract 1800 from 2000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 188614.0366, with a leftover of 0.002.
