155875 ÷ 54 
The aim is to understand the frequency of 54 in 155875.

Let's proceed to step 1:
54 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 54

Step 2:
When dividing 15 by 54, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 54

Advancing to step 3:
If we divide 155 by 54, we get 2 and a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 108 from 155 and we're left with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 54

Advancing to step 4:
If we divide 478 by 54, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 46 after subtracting 432 from 478.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 54

Step 5:
54 goes into 467 8 times with a remainder of 35.
The next digit of our result is 8. 
Result so far: 288.0
Subtract 432 from 467 to get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 54

On to step 6:
54 goes into 355 6 times with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 2886.0
Subtract 324 from 355 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
The number 54 fits into 310 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 2886.5
If we subtract 270 from 310, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 54, we get 7 and a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 2886.57
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 54 fits into 220 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2886.574
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 54 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2886.574
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
400 divided by 54 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 2886.57407
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
If we divide 220 by 54, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 2886.574074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 54, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2886.574074
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 2886.57407407
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 2886.57407407, with a leftover of 2.2e-08.
