Let's divide 408974 by 54
The aim is to understand the frequency of 54 in 408974.

Let's proceed to step 1:
The number 54 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 54

On to step 2:
The number 54 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 54

Going ahead to step 3:
If we divide 408 by 54, we get 7 and a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 378 from 408 leaves us with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 54

On to step 4:
309 divided by 54 is 5 with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
The remainder is 39 after subtracting 270 from 309.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 54

Step 5:
397 divided by 54 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 757.0
Subtracting 378 from 397 leaves us with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 54

Moving on to step 6:
The number 54 fits into 194 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 7573.0
Subtract 162 from 194 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
The number 54 fits into 320 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 7573.5
The remainder is 50 after subtracting 270 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
54 can be fit into 500 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 7573.59
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
54 can be fit into 140 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 7573.592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
320 divided by 54 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 7573.5925
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 54, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 7573.59259
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
If we divide 140 by 54, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 7573.592592
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
If we divide 320 by 54, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7573.5925925
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
When dividing 500 by 54, we get 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 7573.59259259
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 7573.59259259, with a leftover of 1.4e-08.
