Let's divide 99351 by 54
The aim is to understand the frequency of 54 in 99351.

Let's proceed to step 1:
The number 54 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 54

Moving on to step 2:
When dividing 99 by 54, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 54 from 99, we get 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 54

Going ahead to step 3:
54 can be fit into 453 8 times, resulting in a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 432 from 453 and we're left with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 54

Moving on to step 4:
When dividing 215 by 54, we get 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Subtract 162 from 215 to get 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 54

On to step 5:
If we divide 531 by 54, we get 9 and a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 1839.0
Subtract 486 from 531 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 6:
When dividing 450 by 54, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 1839.8
Subtracting 432 from 450 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
54 can be fit into 180 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 1839.83
Subtracting 162 from 180 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
180 divided by 54 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 1839.833
Deduct 162 from 180 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 1839.833 with a remaining 0.0018.
