438227 ÷ 54 
The aim is to understand the frequency of 54 in 438227.

Step 1:
The number 54 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 54

Going ahead to step 2:
If we divide 43 by 54, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 54

Step 3:
54 goes into 438 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 432 from 438 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 54

Step 4:
54 goes into 62 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 54 from 62 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 54

On to step 5:
82 divided by 54 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 811.0
The remainder is 28 after subtracting 54 from 82.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 54

Moving on to step 6:
54 can be fit into 287 5 times, resulting in a remainder of 17.
The next digit of our result is 5. 
Result so far: 8115.0
Deduct 270 from 287 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
When dividing 170 by 54, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 8115.3
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 54, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 8115.31
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
If we divide 260 by 54, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 8115.314
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
If we divide 440 by 54, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 8115.3148
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 54 fits into 80 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 8115.31481
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
54 can be fit into 260 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 8115.314814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
If we divide 440 by 54, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8115.3148148
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
If we divide 80 by 54, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 8115.31481481
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 8115.31481481 with a remaining 2.6e-08.
