We're dividing 53411274 by 809 
The aim is to understand the frequency of 809 in 53411274.

Let's proceed to step 1:
If we divide 5 by 809, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 809

Let's proceed to step 2:
If we divide 53 by 809, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 809

Let's proceed to step 3:
The number 809 fits into 534 0 times, leaving a remainder of 534.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 534 and we're left with 534.
Bring next digit (1) of the dividend behind the 534 and repeat the process: 5341 / 809

Going ahead to step 4:
The number 809 fits into 5341 6 times, leaving a remainder of 487.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4854 from 5341 and we're left with 487.
Fetch the next digit (1) from the dividend, attach it to 487 and continue: 4871 / 809

Step 5:
When dividing 4871 by 809, we get 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtract 4854 from 4871 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 809

Step 6:
When dividing 172 by 809, we get 0 with a remainder of 172.
Put 0 as the next digit of the answer. 
Result so far: 660.0
Subtract 0 from 172 to get 172.
Fetch the next digit (7) from the dividend, attach it to 172 and continue: 1727 / 809

Moving on to step 7:
If we divide 1727 by 809, we get 2 and a remainder of 109.
Use 2 as the next digit of our solution. 
Result so far: 6602.0
If we subtract 1618 from 1727, we get 109.
Append the next digit (4) from the dividend to 109 and continue with: 1094 / 809

Let's proceed to step 8:
809 can be fit into 1094 1 times, resulting in a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 66021.0
If we subtract 809 from 1094, we 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.

Advancing to step 9:
The number 809 fits into 2850 3 times, leaving a remainder of 423.
The next digit of our result is 3. 
Result so far: 66021.3
The remainder is 423 after subtracting 2427 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 10:
809 can be fit into 4230 5 times, resulting in a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 66021.35
Deduct 4045 from 4230 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 11:
If we divide 1850 by 809, we get 2 and a remainder of 232.
Put 2 as the next digit of the answer. 
Result so far: 66021.352
Deduct 1618 from 1850 and we're left 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.

Advancing to step 12:
When dividing 2320 by 809, we get 2 with a remainder of 702.
Use 2 as the next digit of our solution. 
Result so far: 66021.3522
Subtracting 1618 from 2320 leaves us with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

In conclusion, the division gives 66021.3522 with a balance of 0.00702.
