We're dividing 53700419 by 306 
The aim is to understand the frequency of 306 in 53700419.

Going ahead to step 1:
The number 306 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 306

Moving on to step 2:
306 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 306

On to step 3:
If we divide 537 by 306, we get 1 and a remainder of 231.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 306 away from 537, we end up with 231.
Fetch the next digit (0) from the dividend, attach it to 231 and continue: 2310 / 306

Moving on to step 4:
2310 divided by 306 is 7 with a remainder of 168.
The next digit of our result is 7. 
Result so far: 17.0
If we take 2142 away from 2310, we end up with 168.
Take the next digit (0) from the dividend and append it to 168, then repeat: 1680 / 306

Going ahead to step 5:
The number 306 fits into 1680 5 times, leaving a remainder of 150.
The next digit of our result is 5. 
Result so far: 175.0
If we subtract 1530 from 1680, we get 150.
Fetch the next digit (4) from the dividend, attach it to 150 and continue: 1504 / 306

Advancing to step 6:
When dividing 1504 by 306, we get 4 with a remainder of 280.
The next digit of our result is 4. 
Result so far: 1754.0
If we subtract 1224 from 1504, we get 280.
Append the next digit (1) from the dividend to 280 and continue with: 2801 / 306

Let's proceed to step 7:
When dividing 2801 by 306, we get 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 17549.0
If we take 2754 away from 2801, we end up with 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 306

Step 8:
When dividing 479 by 306, we get 1 with a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 175491.0
Subtracting 306 from 479 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 9:
306 goes into 1730 5 times with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 175491.5
If we take 1530 away from 1730, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
2000 divided by 306 is 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 175491.56
The remainder is 164 after subtracting 1836 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
The number 306 fits into 1640 5 times, leaving a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 175491.565
The remainder is 110 after subtracting 1530 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
306 goes into 1100 3 times with a remainder of 182.
Use 3 as the next digit of our solution. 
Result so far: 175491.5653
The remainder is 182 after subtracting 918 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 13:
When dividing 1820 by 306, we get 5 with a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 175491.56535
If we subtract 1530 from 1820, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 14:
306 can be fit into 2900 9 times, resulting in a remainder of 146.
The number 9 becomes the next digit in our result. 
Result so far: 175491.565359
If we take 2754 away from 2900, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 15:
The number 306 fits into 1460 4 times, leaving a remainder of 236.
Use 4 as the next digit of our solution. 
Result so far: 175491.5653594
The remainder is 236 after subtracting 1224 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 16:
306 goes into 2360 7 times with a remainder of 218.
Put 7 as the next digit of the answer. 
Result so far: 175491.56535947
Subtracting 2142 from 2360 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

In conclusion, the division gives 175491.56535947 with a balance of 2.18e-07.
