19547845 ÷ 511 
The aim is to understand the frequency of 511 in 19547845.

Going ahead to step 1:
The number 511 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 511

Step 2:
511 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 511

Advancing to step 3:
The number 511 fits into 195 0 times, leaving a remainder of 195.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 195, we get 195.
Append the next digit (4) from the dividend to 195 and continue with: 1954 / 511

Advancing to step 4:
The number 511 fits into 1954 3 times, leaving a remainder of 421.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1533 away from 1954, we end up with 421.
Include the next digit (7) from the dividend after 421, then repeat: 4217 / 511

Advancing to step 5:
511 can be fit into 4217 8 times, resulting in a remainder of 129.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 4088 from 4217 and we're left with 129.
Include the next digit (8) from the dividend after 129, then repeat: 1298 / 511

Step 6:
1298 divided by 511 is 2 with a remainder of 276.
Write down 2 as next digit of the result. 
Result so far: 382.0
Subtracting 1022 from 1298 leaves us with 276.
Grab the next digit (4) from the dividend, add it to 276, then carry on: 2764 / 511

Moving on to step 7:
The number 511 fits into 2764 5 times, leaving a remainder of 209.
The number 5 becomes the next digit in our result. 
Result so far: 3825.0
If we take 2555 away from 2764, we end up with 209.
Append the next digit (5) from the dividend to 209 and continue with: 2095 / 511

Step 8:
If we divide 2095 by 511, we get 4 and a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 38254.0
If we take 2044 away from 2095, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
511 goes into 510 0 times with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 38254.0
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
511 goes into 5100 9 times with a remainder of 501.
Write down 9 as next digit of the result. 
Result so far: 38254.09
The remainder is 501 after subtracting 4599 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 11:
511 goes into 5010 9 times with a remainder of 411.
Write down 9 as next digit of the result. 
Result so far: 38254.099
If we subtract 4599 from 5010, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

The final result is 38254.099 with a remainder of 0.0411.
