We look at the division of 54857850 by 530 
The aim is to understand the frequency of 530 in 54857850.

Advancing to step 1:
530 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 530

Moving on to step 2:
The number 530 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 530

On to step 3:
530 goes into 548 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 530 from 548 to get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 530

On to step 4:
530 can be fit into 185 0 times, resulting in a remainder of 185.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 185 and we're left with 185.
Append the next digit (7) from the dividend to 185 and continue with: 1857 / 530

Going ahead to step 5:
If we divide 1857 by 530, we get 3 and a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 103.0
Subtracting 1590 from 1857 leaves us with 267.
Bring next digit (8) of the dividend behind the 267 and repeat the process: 2678 / 530

Going ahead to step 6:
If we divide 2678 by 530, we get 5 and a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
If we subtract 2650 from 2678, we get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 530

On to step 7:
530 goes into 285 0 times with a remainder of 285.
The number 0 becomes the next digit in our result. 
Result so far: 10350.0
If we take 0 away from 285, we end up with 285.
Bring next digit (0) of the dividend behind the 285 and repeat the process: 2850 / 530

Moving on to step 8:
530 can be fit into 2850 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 103505.0
The remainder is 200 after subtracting 2650 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 9:
When dividing 2000 by 530, we get 3 with a remainder of 410.
The number 3 becomes the next digit in our result. 
Result so far: 103505.3
Deduct 1590 from 2000 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
If we divide 4100 by 530, we get 7 and a remainder of 390.
Use 7 as the next digit of our solution. 
Result so far: 103505.37
If we take 3710 away from 4100, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 11:
When dividing 3900 by 530, we get 7 with a remainder of 190.
The next digit of our result is 7. 
Result so far: 103505.377
If we take 3710 away from 3900, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 103505.377 with a remainder of 0.019.
