55405909 divided by 307 
The aim is to understand the frequency of 307 in 55405909.

Advancing to step 1:
If we divide 5 by 307, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 307

Step 2:
307 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 307

Let's proceed to step 3:
When dividing 554 by 307, we get 1 with a remainder of 247.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 247 after subtracting 307 from 554.
Take the next digit (0) from the dividend and append it to 247, then repeat: 2470 / 307

Let's proceed to step 4:
2470 divided by 307 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 2456 from 2470, we get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 307

Advancing to step 5:
145 divided by 307 is 0 with a remainder of 145.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Deduct 0 from 145 and we're left with 145.
Include the next digit (9) from the dividend after 145, then repeat: 1459 / 307

Going ahead to step 6:
The number 307 fits into 1459 4 times, leaving a remainder of 231.
Record the quotient 4 as the next digit in the result. 
Result so far: 1804.0
Deduct 1228 from 1459 and we're left with 231.
Include the next digit (0) from the dividend after 231, then repeat: 2310 / 307

On to step 7:
If we divide 2310 by 307, we get 7 and a remainder of 161.
The next digit of our result is 7. 
Result so far: 18047.0
The remainder is 161 after subtracting 2149 from 2310.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 307

Let's proceed to step 8:
307 can be fit into 1619 5 times, resulting in a remainder of 84.
Write down 5 as next digit of the result. 
Result so far: 180475.0
Subtract 1535 from 1619 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
307 goes into 840 2 times with a remainder of 226.
Record the quotient 2 as the next digit in the result. 
Result so far: 180475.2
Subtract 614 from 840 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 10:
If we divide 2260 by 307, we get 7 and a remainder of 111.
The number 7 becomes the next digit in our result. 
Result so far: 180475.27
Subtract 2149 from 2260 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 11:
If we divide 1110 by 307, we get 3 and a remainder of 189.
Use 3 as the next digit of our solution. 
Result so far: 180475.273
Subtracting 921 from 1110 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 12:
The number 307 fits into 1890 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 180475.2736
If we take 1842 away from 1890, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
The number 307 fits into 480 1 times, leaving a remainder of 173.
Put 1 as the next digit of the answer. 
Result so far: 180475.27361
If we subtract 307 from 480, we get 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 14:
307 can be fit into 1730 5 times, resulting in a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 180475.273615
Subtract 1535 from 1730 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 15:
If we divide 1950 by 307, we get 6 and a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 180475.2736156
The remainder is 108 after subtracting 1842 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 16:
1080 divided by 307 is 3 with a remainder of 159.
Use 3 as the next digit of our solution. 
Result so far: 180475.27361563
Deduct 921 from 1080 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final outcome is 180475.27361563, with a leftover of 1.59e-07.
