We divide 3859738 by 300
The aim is to understand the frequency of 300 in 3859738.

Going ahead to step 1:
300 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 300

Step 2:
38 divided by 300 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 300

Step 3:
385 divided by 300 is 1 with a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 300 away from 385, we end up with 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 300

Let's proceed to step 4:
300 can be fit into 859 2 times, resulting in a remainder of 259.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 600 from 859 leaves us with 259.
Fetch the next digit (7) from the dividend, attach it to 259 and continue: 2597 / 300

Going ahead to step 5:
300 can be fit into 2597 8 times, resulting in a remainder of 197.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Deduct 2400 from 2597 and we're left with 197.
Fetch the next digit (3) from the dividend, attach it to 197 and continue: 1973 / 300

Advancing to step 6:
The number 300 fits into 1973 6 times, leaving a remainder of 173.
Put 6 as the next digit of the answer. 
Result so far: 1286.0
The remainder is 173 after subtracting 1800 from 1973.
Fetch the next digit (8) from the dividend, attach it to 173 and continue: 1738 / 300

Going ahead to step 7:
If we divide 1738 by 300, we get 5 and a remainder of 238.
Record the quotient 5 as the next digit in the result. 
Result so far: 12865.0
Subtracting 1500 from 1738 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 8:
If we divide 2380 by 300, we get 7 and a remainder of 280.
The number 7 becomes the next digit in our result. 
Result so far: 12865.7
If we take 2100 away from 2380, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 9:
2800 divided by 300 is 9 with a remainder of 100.
Put 9 as the next digit of the answer. 
Result so far: 12865.79
Subtract 2700 from 2800 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 10:
300 goes into 1000 3 times with a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 12865.793
Subtract 900 from 1000 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.

Going ahead to step 11:
300 goes into 1000 3 times with a remainder of 100.
The next digit of our result is 3. 
Result so far: 12865.7933
Deduct 900 from 1000 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 12865.7933 with a balance of 0.001.
