55666739 ÷ 305 
The aim is to understand the frequency of 305 in 55666739.

Moving on to step 1:
The number 305 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 305

Moving on to step 2:
305 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 305

Moving on to step 3:
When dividing 556 by 305, we get 1 with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 305 from 556 to get 251.
Bring next digit (6) of the dividend behind the 251 and repeat the process: 2516 / 305

Going ahead to step 4:
2516 divided by 305 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 2440 away from 2516, we end up with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 305

Moving on to step 5:
The number 305 fits into 766 2 times, leaving a remainder of 156.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
If we take 610 away from 766, we end up with 156.
Append the next digit (7) from the dividend to 156 and continue with: 1567 / 305

Moving on to step 6:
305 can be fit into 1567 5 times, resulting in a remainder of 42.
The next digit of our result is 5. 
Result so far: 1825.0
If we subtract 1525 from 1567, we get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 305

Advancing to step 7:
The number 305 fits into 423 1 times, leaving a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 18251.0
Subtracting 305 from 423 leaves us with 118.
Append the next digit (9) from the dividend to 118 and continue with: 1189 / 305

Moving on to step 8:
305 can be fit into 1189 3 times, resulting in a remainder of 274.
Use 3 as the next digit of our solution. 
Result so far: 182513.0
Subtract 915 from 1189 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 9:
The number 305 fits into 2740 8 times, leaving a remainder of 300.
Put 8 as the next digit of the answer. 
Result so far: 182513.8
If we subtract 2440 from 2740, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
305 can be fit into 3000 9 times, resulting in a remainder of 255.
Put 9 as the next digit of the answer. 
Result so far: 182513.89
Deduct 2745 from 3000 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 11:
305 can be fit into 2550 8 times, resulting in a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 182513.898
Deduct 2440 from 2550 and we're left 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.

Step 12:
1100 divided by 305 is 3 with a remainder of 185.
Write down 3 as next digit of the result. 
Result so far: 182513.8983
If we subtract 915 from 1100, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 13:
When dividing 1850 by 305, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 182513.89836
If we subtract 1830 from 1850, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
305 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 182513.89836
Subtracting 0 from 200 leaves us 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.

On to step 15:
The number 305 fits into 2000 6 times, leaving a remainder of 170.
The next digit of our result is 6. 
Result so far: 182513.8983606
Subtract 1830 from 2000 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 16:
305 can be fit into 1700 5 times, resulting in a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 182513.89836065
Deduct 1525 from 1700 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The quotient of the division is 182513.89836065, and the remainder is 1.75e-07.
