64619370 ÷ 300 
The aim is to understand the frequency of 300 in 64619370.

Let's proceed to step 1:
When dividing 6 by 300, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 300

Let's proceed to step 2:
300 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 300

Going ahead to step 3:
646 divided by 300 is 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 46 after subtracting 600 from 646.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 300

On to step 4:
461 divided by 300 is 1 with a remainder of 161.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 300 from 461, we get 161.
Take the next digit (9) from the dividend and append it to 161, then repeat: 1619 / 300

Advancing to step 5:
If we divide 1619 by 300, we get 5 and a remainder of 119.
The next digit of our result is 5. 
Result so far: 215.0
The remainder is 119 after subtracting 1500 from 1619.
Grab the next digit (3) from the dividend, add it to 119, then carry on: 1193 / 300

On to step 6:
The number 300 fits into 1193 3 times, leaving a remainder of 293.
The number 3 becomes the next digit in our result. 
Result so far: 2153.0
If we subtract 900 from 1193, we get 293.
Grab the next digit (7) from the dividend, add it to 293, then carry on: 2937 / 300

Step 7:
If we divide 2937 by 300, we get 9 and a remainder of 237.
The number 9 becomes the next digit in our result. 
Result so far: 21539.0
Subtract 2700 from 2937 to get 237.
Bring next digit (0) of the dividend behind the 237 and repeat the process: 2370 / 300

On to step 8:
300 can be fit into 2370 7 times, resulting in a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 215397.0
Subtract 2100 from 2370 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 9:
300 goes into 2700 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 215397.9
The remainder is 0 after subtracting 2700 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
300 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 215397.9
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 300 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 215397.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 215397.9 with a remaining 0.0.
