Let's divide 312912 by 54
The aim is to understand the frequency of 54 in 312912.

Going ahead to step 1:
54 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 54

Let's proceed to step 2:
The number 54 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 54

Step 3:
The number 54 fits into 312 5 times, leaving a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 270 from 312 to get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 54

Going ahead to step 4:
When dividing 429 by 54, we get 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 378 from 429 leaves us with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 54

Step 5:
54 goes into 511 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 579.0
Deduct 486 from 511 and we're left with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 54

Step 6:
54 can be fit into 252 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 5794.0
If we subtract 216 from 252, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
54 goes into 360 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 5794.6
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
54 can be fit into 360 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 5794.66
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 5794.66, with a leftover of 0.036.
