We're dividing 45818 by 809 
The aim is to understand the frequency of 809 in 45818.

Let's proceed to step 1:
809 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 809

Step 2:
The number 809 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 809

Step 3:
809 can be fit into 458 0 times, resulting in a remainder of 458.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 458 after subtracting 0 from 458.
Fetch the next digit (1) from the dividend, attach it to 458 and continue: 4581 / 809

Step 4:
When dividing 4581 by 809, we get 5 with a remainder of 536.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4045 away from 4581, we end up with 536.
Grab the next digit (8) from the dividend, add it to 536, then carry on: 5368 / 809

Moving on to step 5:
809 can be fit into 5368 6 times, resulting in a remainder of 514.
The next digit of our result is 6. 
Result so far: 56.0
The remainder is 514 after subtracting 4854 from 5368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 6:
809 can be fit into 5140 6 times, resulting in a remainder of 286.
The number 6 becomes the next digit in our result. 
Result so far: 56.6
Deduct 4854 from 5140 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 7:
If we divide 2860 by 809, we get 3 and a remainder of 433.
Use 3 as the next digit of our solution. 
Result so far: 56.63
The remainder is 433 after subtracting 2427 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 8:
809 can be fit into 4330 5 times, resulting in a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 56.635
Subtract 4045 from 4330 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 9:
If we divide 2850 by 809, we get 3 and a remainder of 423.
The number 3 becomes the next digit in our result. 
Result so far: 56.6353
If we subtract 2427 from 2850, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 10:
4230 divided by 809 is 5 with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 56.63535
If we subtract 4045 from 4230, 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.

Moving on to step 11:
809 goes into 1850 2 times with a remainder of 232.
The next digit of our result is 2. 
Result so far: 56.635352
Subtracting 1618 from 1850 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
If we divide 2320 by 809, we get 2 and a remainder of 702.
Record the quotient 2 as the next digit in the result. 
Result so far: 56.6353522
The remainder is 702 after subtracting 1618 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Our division results in 56.6353522 with a remaining 7.02e-06.
