We divide 171813 by 54
The aim is to understand the frequency of 54 in 171813.

On to step 1:
If we divide 1 by 54, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 54

Going ahead to step 2:
The number 54 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 54

Moving on to step 3:
The number 54 fits into 171 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 162 away from 171, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 54

Step 4:
When dividing 98 by 54, we get 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 44 after subtracting 54 from 98.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 54

Moving on to step 5:
54 goes into 441 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
Subtracting 432 from 441 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 54

Going ahead to step 6:
54 goes into 93 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 3181.0
Subtract 54 from 93 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
390 divided by 54 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 3181.7
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
54 can be fit into 120 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 3181.72
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
54 goes into 120 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 3181.722
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 3181.722 with a balance of 0.0012.
