Let's divide 51027873 by 306
The aim is to understand the frequency of 306 in 51027873.

Step 1:
306 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 306

Going ahead to step 2:
51 divided by 306 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 306

Let's proceed to step 3:
306 can be fit into 510 1 times, resulting in a remainder of 204.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 306 from 510 and we're left with 204.
Grab the next digit (2) from the dividend, add it to 204, then carry on: 2042 / 306

On to step 4:
If we divide 2042 by 306, we get 6 and a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 1836 from 2042, we get 206.
Take the next digit (7) from the dividend and append it to 206, then repeat: 2067 / 306

Let's proceed to step 5:
The number 306 fits into 2067 6 times, leaving a remainder of 231.
Use 6 as the next digit of our solution. 
Result so far: 166.0
Deduct 1836 from 2067 and we're left with 231.
Take the next digit (8) from the dividend and append it to 231, then repeat: 2318 / 306

Advancing to step 6:
The number 306 fits into 2318 7 times, leaving a remainder of 176.
Record the quotient 7 as the next digit in the result. 
Result so far: 1667.0
If we take 2142 away from 2318, we end up with 176.
Append the next digit (7) from the dividend to 176 and continue with: 1767 / 306

Moving on to step 7:
When dividing 1767 by 306, we get 5 with a remainder of 237.
Put 5 as the next digit of the answer. 
Result so far: 16675.0
Subtracting 1530 from 1767 leaves us with 237.
Fetch the next digit (3) from the dividend, attach it to 237 and continue: 2373 / 306

Advancing to step 8:
If we divide 2373 by 306, we get 7 and a remainder of 231.
The next digit of our result is 7. 
Result so far: 166757.0
Subtracting 2142 from 2373 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 9:
When dividing 2310 by 306, we get 7 with a remainder of 168.
Write down 7 as next digit of the result. 
Result so far: 166757.7
Subtract 2142 from 2310 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 10:
306 can be fit into 1680 5 times, resulting in a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 166757.75
Subtracting 1530 from 1680 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
The number 306 fits into 1500 4 times, leaving a remainder of 276.
Put 4 as the next digit of the answer. 
Result so far: 166757.754
Subtracting 1224 from 1500 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 12:
When dividing 2760 by 306, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 166757.7549
The remainder is 6 after subtracting 2754 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
306 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 166757.7549
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
306 can be fit into 600 1 times, resulting in a remainder of 294.
Use 1 as the next digit of our solution. 
Result so far: 166757.754901
Subtracting 306 from 600 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 15:
306 can be fit into 2940 9 times, resulting in a remainder of 186.
The next digit of our result is 9. 
Result so far: 166757.7549019
Subtract 2754 from 2940 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 16:
306 can be fit into 1860 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 166757.75490196
The remainder is 24 after subtracting 1836 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 166757.75490196 with a balance of 2.4e-08.
