4480593 divided by 809 
The aim is to understand the frequency of 809 in 4480593.

Moving on to step 1:
809 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 809

On to step 2:
44 divided by 809 is 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 809

Going ahead to step 3:
If we divide 448 by 809, we get 0 and a remainder of 448.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 448, we end up with 448.
Fetch the next digit (0) from the dividend, attach it to 448 and continue: 4480 / 809

Let's proceed to step 4:
The number 809 fits into 4480 5 times, leaving a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 435 after subtracting 4045 from 4480.
Append the next digit (5) from the dividend to 435 and continue with: 4355 / 809

Step 5:
809 can be fit into 4355 5 times, resulting in a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we take 4045 away from 4355, we end up with 310.
Grab the next digit (9) from the dividend, add it to 310, then carry on: 3109 / 809

Step 6:
If we divide 3109 by 809, we get 3 and a remainder of 682.
Put 3 as the next digit of the answer. 
Result so far: 553.0
If we take 2427 away from 3109, we end up with 682.
Include the next digit (3) from the dividend after 682, then repeat: 6823 / 809

Advancing to step 7:
When dividing 6823 by 809, we get 8 with a remainder of 351.
Put 8 as the next digit of the answer. 
Result so far: 5538.0
Subtracting 6472 from 6823 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 8:
809 can be fit into 3510 4 times, resulting in a remainder of 274.
The next digit of our result is 4. 
Result so far: 5538.4
The remainder is 274 after subtracting 3236 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 9:
809 can be fit into 2740 3 times, resulting in a remainder of 313.
The next digit of our result is 3. 
Result so far: 5538.43
Subtract 2427 from 2740 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 10:
809 goes into 3130 3 times with a remainder of 703.
Write down 3 as next digit of the result. 
Result so far: 5538.433
Subtract 2427 from 3130 to get 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

The final result is 5538.433 with a remainder of 0.0703.
