We look at the division of 944399 by 54 
The aim is to understand the frequency of 54 in 944399.

Going ahead to step 1:
If we divide 9 by 54, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 54

On to step 2:
54 can be fit into 94 1 times, resulting in a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 40 after subtracting 54 from 94.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 54

Step 3:
When dividing 404 by 54, we get 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 378 from 404 leaves us with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 54

Let's proceed to step 4:
If we divide 263 by 54, we get 4 and a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
Subtract 216 from 263 to get 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 54

Going ahead to step 5:
The number 54 fits into 479 8 times, leaving a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 1748.0
Subtract 432 from 479 to get 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 54

On to step 6:
When dividing 479 by 54, we get 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 17488.0
Deduct 432 from 479 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
470 divided by 54 is 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 17488.8
Subtract 432 from 470 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
380 divided by 54 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 17488.87
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 54, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17488.87
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 54, we get 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 17488.8703
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
54 can be fit into 380 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 17488.87037
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
When dividing 20 by 54, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 17488.87037
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
54 can be fit into 200 3 times, resulting in a remainder of 38.
The next digit of our result is 3. 
Result so far: 17488.8703703
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
When dividing 380 by 54, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 17488.87037037
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 17488.87037037 with a balance of 2e-09.
