The aim is to understand the frequency of 909 in 37677040.

On to step 1:
3 divided by 909 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 909

Moving on to step 2:
909 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 909

Step 3:
909 can be fit into 376 0 times, resulting in a remainder of 376.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 376 to get 376.
Append the next digit (7) from the dividend to 376 and continue with: 3767 / 909

Advancing to step 4:
3767 divided by 909 is 4 with a remainder of 131.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3636 from 3767, we get 131.
Grab the next digit (7) from the dividend, add it to 131, then carry on: 1317 / 909

Step 5:
When dividing 1317 by 909, we get 1 with a remainder of 408.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 909 from 1317 and we're left with 408.
Bring next digit (0) of the dividend behind the 408 and repeat the process: 4080 / 909

On to step 6:
909 can be fit into 4080 4 times, resulting in a remainder of 444.
The next digit of our result is 4. 
Result so far: 414.0
If we subtract 3636 from 4080, we get 444.
Fetch the next digit (4) from the dividend, attach it to 444 and continue: 4444 / 909

Moving on to step 7:
When dividing 4444 by 909, we get 4 with a remainder of 808.
The next digit of our result is 4. 
Result so far: 4144.0
Subtract 3636 from 4444 to get 808.
Take the next digit (0) from the dividend and append it to 808, then repeat: 8080 / 909

Let's proceed to step 8:
The number 909 fits into 8080 8 times, leaving a remainder of 808.
Write down 8 as next digit of the result. 
Result so far: 41448.0
If we take 7272 away from 8080, we end up with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Let's proceed to step 9:
8080 divided by 909 is 8 with a remainder of 808.
Write down 8 as next digit of the result. 
Result so far: 41448.8
Subtracting 7272 from 8080 leaves us with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Let's proceed to step 10:
909 can be fit into 8080 8 times, resulting in a remainder of 808.
Use 8 as the next digit of our solution. 
Result so far: 41448.88
Subtracting 7272 from 8080 leaves us with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Our division results in 41448.88 with a remaining 0.808.
